Database Development Jobs

This project merges two core objectives—talent acquisition and revenue generation—into one seamless web experience. On the recruitment side, I need a database-driven module that lets me post open positions, track applicants through each hiring stage, and collect resumes in a structured, searchable format. Candidates should be able to create a profile, upload documents, and monitor their application status; I want corresponding admin views that let me filter, tag, and comment on each record. The same site will also house a sales area, so the overall architecture must be flexible enough to incorporate catalog and checkout features without rebuilding the foundations later. Clean separation of concerns, reusable components, and an extensible schema are therefore essential. Core d...

I need to homologate some fields of the account creation of the Accounting module of Ultimatepos to the PUC chart of accounts for Colombia, and that this data is stored correctly in the database which allows me to create accounts organized according to the chart of accounts for Colombia, and allows me to map all transactions correctly

I need an IBM Infosphere MDM specialist who can take ownership of our data-integration layer and help me raise accuracy and consistency across the platform. The engagement is fully remote but you must sit somewhere in Europe so we can work within a comfortable time-zone overlap; fluent English is essential for day-to-day collaboration. My priority is Data Integration. Multiple operational databases, several cloud services and a growing set of partner-facing APIs all need to flow cleanly into the MDM hub. I already have core MDM services online, yet duplicate records and mismatched attributes keep creeping in. Your job is to analyse the current ingestion routes, design (or redesign) the mappings, and configure the Infosphere components—Integration Hub, DataStage, QualityStage, or a...

I need a sizeable, up-to-date database of medium-sized U.S. companies that spans every sector—healthcare, retail, technology, and any other field you can reach. For every record I only require two data points: a direct phone number and a working email address and company name and person name. Accuracy matters more than sheer volume, so I’ll be checking for bounced emails, disconnected lines, and duplicates before releasing final approval. Please deliver the file in Excel. Include one row per company contact, clearly labeled columns, and make sure the data has been gathered ethically and is compliant with U.S. privacy laws. I will consider the job complete once: • at least 95 % of emails pass validation tools such as ZeroBounce or NeverBounce, • phone numbers are c...

I need a clean, reliable bridge that moves data from Tally into my PostgreSQL database through Tally Definition Language. The goal is seamless, automated integration—no manual exports, no Excel hops—so that every voucher, ledger, and stock movement recorded in Tally lands in dedicated tables inside Postgres in near-real time. Here’s what matters to me: • TDL code that hooks into the relevant Tally events and packages the data for transfer. • A lightweight service or script on the Postgres side that receives the payload and inserts or updates the right tables. • Clear mapping documentation so I can see which Tally fields end up in which database columns. • Basic error handling and a simple log so I know when something fails. I already have the...

Expert level only. Provide your approach and timeline in proposal. Start immediately.

I need a fresh database—built entirely from scratch—of accounting decision-makers who work inside finance-sector companies with more than 200 employees. The specific titles I care about are Accounts Payable, Accounts Receivable, Controller, Bookkeeper, Senior Accountant, and CFO. Each record must include a working LinkedIn profile URL plus the contact’s ZohoMail corporate email address. Deliverables • An Excel or CSV file containing: First Name, Last Name, Job Title, Company, Company Size, Industry, LinkedIn URL, ZohoMail Address, and a brief verification note • Emails validated so the bounce rate stays below 5 % I’ll spot-check accuracy by sampling both the LinkedIn links and the emails, so only submit details you are confident will pass. Once t...

I need to bring several Visual FoxPro databases up to modern standards while also building a fresh one from scratch. On the legacy side, the structure needs a careful redesign so tables, indexes, and relations make sense for today’s workflows. As part of that redesign, stale and duplicate records have to be cleansed, and performance tuned so queries return instantly rather than in minutes. Once the data is sound, I want clear, professional-looking reports and analytics dashboards that management can run with a single click. The new database should follow the same architecture and optimisation principles so it integrates cleanly with our existing codebase. Everything must stay native to Visual FoxPro; however, if a lightweight helper tool (e.g., SQL Server Express or Power BI for t...

I need a well-structured, up-to-date Italian B2C database that will let me run highly targeted marketing campaigns. My immediate focus is on contacts who fall, so please keep non-relevant entries to a minimum. The file should contain at least these fields for every record: • Email address • Phone number (mobile or landline) • Full mailing address (street, city, ZIP/post code) If you also track extras such as age range, purchasing behaviour, or other demographic tags, let me know—those bonus details could tip the scale in your favour. Send a brief overview of: 1. Total number of unique records you can provide. 2. Verification date or method you use to keep the data current. 3. Expected hard-bounce or invalid rate. A clean CSV or Excel workbook is ideal. ...

Our landscape construction firm juggles dozens of jobs at any given time, and I need a cloud-based system that tracks each project from the first bid through final hand-off. The core will sit on Firebase so the team can enjoy real-time updates wherever they are on site or in the office. What I need you to build • A relational structure in Firestore that clearly separates bidding, construction, and close-out data yet lets us call up every contract, invoice, plan, or photo in seconds. Documents themselves should live in Firebase Storage, linked back to their parent records. • Robust, role-based user access: estimators see bids, project managers see active jobs, finance sees invoices, and admins see everything. • Instant synchronization so two people never overwrite each...

I’m building a master outreach database and need a reliable researcher to source and verify email contacts of manufacturers based in mainland China. The priority sectors are Electronics, Textiles and Automotive parts, but I also want to cover heavy machinery, logistics, shipping and bunkering companies so I can target a broader supply chain. Every address must pass an email-verification service (Hunter, NeverBounce, ZeroBounce—use whatever you prefer as long as the result shows “deliverable”), ensuring the list is ready for immediate campaigns with no hard bounces. Please focus on three job functions only: Sales Representatives, Export Managers and General Managers. I’m not interested in generic “info@” or “sales@” inboxes; named, rol...

I’m putting together a comprehensive student-lead database for the 2026 intake across universities in India and need a specialist who can capture solid, verified contacts through online forms. The focus is strictly on student leads—faculty or administrative data may become relevant in the future, but for now it’s outside the scope. Here’s what I need from you: • Build, host, and optimise online data-capture forms that feel trustworthy and mobile-friendly. • Drive traffic to those forms using channels you recommend (unpaid or paid is fine as long as it stays compliant with university policies and Indian data-protection rules). • Deliver a clean spreadsheet containing each student’s name, email address, and active phone number. No other data...

I’m building an internal security tool and need a solid PostgreSQL foundation that starts as a single, multi-tenant database yet can be cleanly split into separate databases—and separate servers—later on. The first release will concentrate on storing architectural components (a very well defined structure) alongside threat-intelligence data (mapped to the components metadata), so the schema must keep cross-tenant isolation strict while still allowing swift relational join matching across those two domains. What I need from you • A full relational schema (ERD and DDL) optimised for multi-tenant operation—think shared-table with isolated tenant-id or schema-per-tenant, whichever you can justify—and documented so the eventual extraction path is clear. &...

Remember this should work offline environment I have a batch of English-language PDFs that were scanned as images. Each file contains a mix of cleanly typed passages and more challenging handwritten notes in the margins. I need every legible word pulled out with the highest accuracy you can achieve and stored directly in a MySQL database, not as flat files. Accuracy matters more than speed; feel free to combine engines such as Tesseract, Google Vision, or AWS Textract—whatever blend gives you the best recognition rate on both printed and cursive text. Pre-processing for skew, noise, and contrast is expected so the handwriting is captured as reliably as the typed sections. The database is already provisioned; I will share connection details and a simple schema suggestion (doc_id, p...

I run a warehouse where every item sits on a clearly numbered rack and many products leave the floor as packed bales. I need a complete stock-control solution that can live either in a standalone application or an advanced, well-structured Excel workbook—whichever you feel delivers the cleanest workflow and fastest user adoption. Core functions I must see working: • Real-time rack-wise stock list that tells me exactly what is physically on hand. • A packed-bale register that stores destination and handling instructions alongside each bale number. • Daily report that flags any quality or SKU that sold out in the last 24 hours. • Automated analytics highlighting top sellers, slow movers and the exact “age” of every item in days. • Barcode ...

The goal is to design a future-proof relational backbone for a multi-channel retail platform, built natively on PostgreSQL. I already run an operational system, and its live transactional records will have to be migrated into the new structure without downtime. Everything else—users, inventory, orders—will start fresh. Core design expectations The operational schema should be fully normalised to 3NF and optimised from day one for high concurrency. Think table partitioning (range and list), well-chosen GIN and B-Tree indexes, plus JSONB columns where semi-structured flexibility makes sense. Triggers, constraints and stored procedures must enforce business logic consistently, so the application tier can stay lightweight. Analytics layer Alongside the OLTP schema I need a se...

I need a turnkey solution that watches a dedicated folder on our local server, reads every stock-dispatch PDF dropped there, and pulls out the roll-level details we receive from multiple vendors—Micron, Size, Roll Number, Gross Weight, Net Weight, Invoice Number, Vendor Name and Dispatch Date. Once captured, that data must flow straight into a master inventory database, stay synchronised, and drive all downstream reports. Key functions I expect: • Continuous PDF scraping from the local path I specify, with no manual trigger required. • Central master inventory that grows with each import; I’m open to whichever SQL back-end you feel best suits the job as long as it is industry-standard and easy for us to maintain. • Live stock dashboards that let me view ba...

If you are expert in building Oracle AI agents and if you have the fusion experience then only bid this project. payment will be released only if the project satisfied or else no payment. it needs to be remote work you just need to guide me i will do in my system. I have a Fusion Application instance and want to layer Oracle AI Agent Studio on top of it so that key customer-facing actions happen automatically. The flow is straightforward: • The agent picks up promise dates and status changes from Fusion. • It updates the relevant “Notes” field in real time. • If a promise is missed, the agent triggers an email to the customer (and a copy to our team). Few of theAPI keys are already available; I simply need you to wire them into Oracle AI Agent Studio, c...

i want to create MS Access database sheet requirement database not to big or hard Database Requirement Explanation I belong to the Indian Army. My unit has a strength of approximately 445 personnel. Every year, individuals remain embodied (on service) and disembodied (service break) for varying periods, usually ranging from 1 to 4 months at a time. I want to create a database (preferably in MS Access) where each individual has a separate profile, and all service periods are calculated automatically. ⸻ Individual Profile Requirements Each individual profile should contain: • Army Number • Rank • Name • Date of Enrollment Example: Army No: 1245 Rank: Sepoy Name: Pankaj Date of Enrollment: 01 Dec 2015 ⸻ Embodiment / Disembodiment Logic For each individual, there can be m...

I need a reliable solution that can pull data from LinkedIn and insert it straight into a database I specify. The core requirement is the automated transfer—once the tool finishes scraping, every captured field should already be sitting in the database ready for queries and reporting, no manual copy-paste. You’ll advise me on the best approach to authenticate, respect rate limits, and minimise the risk of blocks while still collecting the typical profile-level details (name, headline, company, location, experience, education, skills and anything else you can legally obtain). I will confirm the final field list before you begin. Key objectives • Build or configure a scraper / API wrapper that logs in, navigates to each target profile and captures the agreed-upon fields ...

I have a fully-functional ERP written in core PHP with a MySQL backend. The next milestone is an Inventory Management module dedicated exclusively to stock tracking. No supplier or order features are needed at this stage. What I need built • Database changes to record products, stock movements (in, out, adjustments) and current on-hand quantities. • Clean, responsive PHP screens that blend with the existing UI for item setup, stock transactions and a real-time stock level dashboard. • Basic search, filter and export to CSV so staff can pull quick counts. • Low-stock thresholds with email alerts (SMTP already configured in the system). • Clear install/merge instructions and brief user documentation. Acceptance The module must install without breaking e...

I need a fresh, fully-verified database of construction businesses operating anywhere in the United Kingdom. Each record must contain these four fields: business name, direct email address, contact phone number and the company’s trade specialism. Priority sectors are Plumbing, Electrical, Carpentry, Housing & commercial developers and Civil engineering, but I’m happy to accept additional reputable trades if you have them—“any” useful construction lead is welcome as long as the data meet the same quality bar. Please deliver the list in a clean Excel or Google Sheet. I’ll spot-check for duplicates, hard bounces and obvious inaccuracies, so only recent, GDPR-compliant contacts should make the cut. Let me know the volume you can supply, how you verify ...

I currently manage a website built for display management. It runs on a Linux server with an SQL database. Over time, the system has slowed down and is struggling to handle the increasing volume of data efficiently. The goal is to redesign the website using modern technologies and update the overall architecture to improve performance and scalability. All page designs have already been completed in Figma. The platform synchronizes its main database with local databases on connected desktop workstations, and the new version must remain fully compatible with the existing desktop software to ensure seamless synchronization. There are three user roles: Super Admin, Admin, and User, each with specific permissions to manage or view different levels of content. In addition, the UI needs to be...

I want to launch a fully-featured, cloud-hosted lottery platform built on a hardened Node.js backend with a reliable database layer. New players will sign up with a classic email-and-password flow, then complete KYC before they can fund their wallet or join a draw. The exact KYC data points can be finalised together, but the process must be seamless and compliant. Core flow • A user tops up an internal wallet via PayPal (gaming category enabled), buys entries, and watches their balance update in real time. • On draw day a server-side, provably-fair randomiser selects winners; every draw, ticket purchase, and payout is written to an immutable audit log. • From my side I need an admin dashboard that shows live player stats, transaction history, and lets me trigger or sc...

Two product modes in one codebase A) Hospitality (Restaurant / Bar) Windows POS touchscreen: tables & floorplan, open tickets, split/merge/move, void/refund, discounts, VAT/tax rules Android handheld ordering (PWA or native): fast ordering per table, live sync with POS + KDS, offline queue + retry KDS (Kitchen Display System): new → preparing → ready, station routing (kit...

I need a clean, accurate database of 15,000 accounts-payable contacts at privately-owned companies across the United States. For every record I must have the person’s full name, job title, company name, corporate email, and direct phone. These addresses must pass an email-verification sweep (NeverBounce, ZeroBounce or comparable software) so the final file is ready for outreach with a very low bounce rate. My ideal file arrives as a single CSV or Excel workbook that includes the verification status for each email plus a summary report from the tool you used. Bounce-free delivery is essential; anything over 2 % will require replacement. Please source only true A/P decision makers—no generic “info@” or “sales@” inboxes—and avoid public-sector organ...

I need a techno-functional specialist who knows SAP HANA inside-out to set up an automated pipeline that pulls data from three live modules—Financial (FI), Production Planning (PP) and Plant Maintenance (PM)—and ships it to a remote server on a fixed schedule. Here is what I am after: • Build or configure the job inside HANA Server (HANA DB with query language access, or any proven method you recommend... No additional connector licenses will be bought) so that it extracts the required tables and views, converts the output to clean JSON and pushes it to the destination path via SFTP or a comparable secure protocol. • The transfer must run on a schedule that I can adjust easily (hourly, daily thrice weekly, etc.) without redeploying code. Preferably leave the cr...
