PostgreSQL Jobs

I’m spinning up a Java 21/ Spring Boot backend and need a capable pair of hands to get the core REST layer in place while walking me through the logic so I can learn as we go. The immediate priority is clean, well-structured REST API creation. I need endpoints for standard CRUD (GET, POST, DELETE) that persist to postgres, and I’d like them written the “Spring way” with proper service, repository and DTO layers. Beyond the basics, the service must also handle batch workloads and expose certain operations through AWS Lambda. File uploads will live in S3, so the API should integrate with the AWS SDK, and everything should be protected with authentication/authorization (Spring Security or similar). • REST endpoints: GET, POST, DELETE plus batch routes and ...

I have a mature VS Code extension but it still needs a final push before we can release it publicly in roughly four weeks. The core codebase is solid; what’s missing are several new user-facing features, chiefly UI improvements along with an upgraded admin console and browser console. I’d also like to revisit the overall software architecture to make sure it scales cleanly once the user base grows. You’ll be dropping into a stack built with TypeScript, React, , PostgreSQL, Redis, and Docker, so hands-on proficiency with those tools is critical. In addition to coding, I’m counting on you to help outline and document an architecture that’s easy for other engineers to pick up later. Because time is short, I need someone who can start immediately and show eviden...

I’m spinning up a new backend and want a hands-on developer who can jump straight into building production-ready, secure APIs. The stack is Node.js with Express, PostgreSQL on the data layer, and Microsoft Graph for several integration points. You should already be comfortable handling OAuth flows and token management because authentication is wired through Azure AD. My priority is robustness: clean, well-documented endpoints, solid error handling, and security baked in from the start. If you have experience tightening Node.js applications against attack vectors, you’ll feel at home here. Please tell me about projects where you built or hardened APIs on a similar stack. I’m particularly interested in how you approached authentication with Microsoft Graph or secured Post...

I need a confident Node.js developer who can jump straight into the server code with me. We will lean heavily on Cursor/claude/antigravity as our day-to-day AI assistant, so prior experience prompting and steering that tool is essential. Our shared focus is to wire the backend to Microsoft Graph, expose clean REST endpoints, and make sure every call is authenticated, logged, and persisted. Concretely, the backend must support: • User authentication • Database management • API integrations PostgreSQL is the Database. Your job will be to flesh it out, write the data-access layer, and keep performance in mind from the outset. On the Microsoft Graph side, we’ll be handling email, calendar, so familiarity with the Graph SDK for Node or crafting raw OAuth calls will ...

I’m putting together a web-based map portal that will sit on Mapbox and show the live condition of eight separate water-utility datasets. Each point on the map needs a clear visual status (for example “operational”, “under maintenance”, “offline”) that I can change in real time. From a phone or tablet I also want to be able to add entirely new points on the fly, fill in a small form, upload a photo if needed, and see the record appear for everyone else instantly. Access will be gated by a very simple login—one user role only—just enough to keep the data private without the complexity of multiple permission tiers. Once signed in, the user should land straight on the map, filter layers on or off, search, click a feature, and edit its att...

About the job About the Project I'm building a high-scale headless browser automation and experimentation framework that will: • Run thousands of browser sessions in parallel for testing, data collection, and content experiments. • Start life on a single VPS, and later move onto a dedicated on prem server • Integrate with an existing Java/Appium codebase, but the new core will be containerized, observable, and easy to scale. This is not a traditional CRUD app. It's closer to building the backbone for a mini cloud: containers, queues, orchestration, metrics, and clean deployment. I'm looking for a hands-on backend/infra engineer who is comfortable owning the base platform end-to-end. Who I'm Looking For Must-Have Skills • Strong experience on Linux se...

My company already has a working client-facing application with a backend that handles device control, real-time communication, and user accounts. The problem is scalability: as we release more hardware, the current architecture strains under heavy device management and the real-time layer shows cracks. Where the system falls short • Device management can’t comfortably grow with our roadmap. I need to raise overall device capacity and integrate richer performance-monitoring metrics without compromising responsiveness. • Real-time communication works, but reliability drops when traffic spikes; improving that stability is critical. What I’d like from you • Review the existing codebase and architecture (Node.js, MQTT, PostgreSQL—full repo access provided)...

I’m building a multi-tenant Healthcare Management System delivered as a SaaS product and need a solid Django back-end to power it. The core modules already outlined are patient management, billing & payments, and appointment scheduling, all exposed through a well-documented REST API so web and mobile front-ends can consume them easily. Beyond the basics, the system must connect smoothly with external Electronic Health Record systems (FHIR or HL7 endpoints), standard payment gateways, and insurance-provider APIs, passing data securely and logging every transaction for audit purposes. Role-based access is critical: doctors, administrators and patients will each see only what they should, so fine-grained permissions, robust authentication (JWT or OAuth2) and an activity trail are e...

I’m running a Laravel-based property platform that already embeds about 50 000 images with CLIP / SigLIP and stores them in PostgreSQL through pgvector. Both prompt→image and image→image search are live, yet the similarity scores are loose—typing “swimming pool” still pulls in shots of the open sea. I need someone who has actually deployed vector search in production to step in and tighten the results. Where I think we can get immediate wins • Re-examining our pgvector indexing strategy (IVFFlat vs HNSW parameters, segment counts, probe settings) and rebuilding indexes where needed. • Profiling and rewriting the current SQL so distance ordering is mathematically correct and not masked by Laravel’s query builder quirks. • Verifyi...

I need an experienced developer to step into my existing Node.js application (deployed on AWS with a PostgreSQL database) and push it to the next level. My primary goal is to enhance the current codebase—not start from scratch—so you’ll be working with what’s already there, polishing it, and extending its capabilities. Where I most need your help is in refining some existing changes that were left half-done and then developing a new service that plugs cleanly into the architecture. The code already runs, but it can definitely run better; I’m keen on anything you can do to streamline database calls, tighten up AWS resource usage, or otherwise boost performance while you’re in the code. Deliverables I expect: • Updated Node.js modules and AWS resour...

I am setting up a small-scale information system and need hands-on help with the database side of things. The technical focus is clearly on database management—designing simple tables, defining relationships, writing basic SQL queries, and showing me how to keep everything tidy and backed up. Because I’m still at the beginner stage, I’m looking for someone who can walk me through each step patiently, explain core concepts such as normalization, indexing, and basic security practices, and leave me with clear, reusable examples (scripts, ER diagrams, short notes). Soft skills matter as much as the technical ones. I value clear communication, the ability to break down problems into manageable pieces, and a collaborative attitude that encourages questions. If you can pair co...

So currently we have a discord bot in GO and the three things I need help fixing are: 1. The queueing system Essentially the issue is rate limits so right now we have a working queue system (users enter, queue gets full, voice channels created, thread created and then players can start their game) But the issue is these are heavy on rate limits so we would like to have mini bots who are able to do this and move the functionality to them/have them retry so players are never stuck in a state. And on the backend it’s hooked up to a Postgres database where users who are registered their games get logged/scored and when games are created/finished or staff score the game they update. 2. Image generation/AI Reading There are a couple of commands that we would like to display with a phot...
