I run a small events-and-operations team and I’m looking for a reliable virtual assistant who can take full ownership of our data entry backlog. The work is strictly database management: migrating contact lists from spreadsheets, cleaning and de-duplicating existing records, tagging entries with the correct event or client codes, and keeping our online CRM up to date so the rest of the team can plan each event without scrambling for accurate numbers. You’ll log in to our web-based database and, using the import tools and validation rules already in place, enter or update approximately 300–400 records a week. Consistent formatting, zero duplicates, and correctly linked relational fields are essential; I’ll spot-check your first batch to confirm everyth...

...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 the front-end analytics layer) makes sense, I’m open to your recommendation, provided the core remains in VFP. Deliverables • Updated schema for the current VFP database, fully documented • Cleaned and optimised data set with repeatable scripts • A brand-new VFP database built on the revised architecture • A suite of parameter-driven reports and ana...

...policy. Here is where I need you: • Architectural kick-off – I want rock-solid design patterns and best practices from day one, with security woven through every layer and a flexible auth system that can evolve as requirements shift. • Front-end / back-end integration – Help me keep the wiring clean so new modules or UI components can be dropped in without a full rewrite. • Ongoing pair-programming / troubleshooting – When my junior developer hits a snag, I’d like you to step in on an hourly basis, untangle the issue, explain the fix and leave behind actionable notes so we learn as we go. The consults will be remote and ad-hoc, so clear communication and the patience to dive into “in-the-weeds” problems are essential. If y...

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 ...

Two live, one-hour screen-sharing sessions will kick-start our work with Clay AI. Session #1 needs to dive straight into performing Google Map searches inside Clay and then pushing those enriched results back into our current database. I also want clear guidance on defining triggers and actions, setting up reliable notifications, and keeping the data model tidy through proper database normalization. If extra time is needed after the first two calls, I am happy to book follow-up sessions so I leave feeling fully confident building entire Clay workflows from scratch, tweaking simple custom AI models, and exporting everything cleanly. Any screen-sharing platform—Zoom, Google Meet, Skype, or whichever tool you prefer—is fine as long as we can see each other’...

...of the websites have tokens that have to be initiated that keep changing. All of the sites are getting scraped except for one has a problem. You will fix that. This scraper is also inputting the incorrect price into our database and you will need to fix that as well. Heres how the system works: Prices are scraped from several theme park websites. Then they are ran thru a calculation algorithm to determine what our price should be. All the sites are inputting the correct prices except for universal. You will fix that (Currently its putting the scraped price in our database and not the calculated price like it should). All the calculations are there already, for some reason its not being utilized for that particular theme park. That is fix 1. Fix 2 is to automatically ref...

I need a solid, campaign-ready outreach list of manufacturers operating in Mainland China, with a primary emphasis on the Textiles sector but also covering Electronics, Automotive Parts, Heavy Machinery, Logistics, Shipping, and Bunkering.

What I need now is an experienced full-stack Web3 developer who can tie up the loose ends, harden the code and get us to a production launch. Key gaps to close • Merchant dashboard polish – merchants must be able to generate API keys, configure webhooks, and choose between HD/xpub or static wallet addresses. • Checkout edge cases – customers see a payment address and live status updates; the status must stay accurate even on slow or re-orged blocks. • Reliable notifications ...

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.
