Database Programming Jobs

Production Solana copy-trading bot for Solana Hyperion Solana Hyperion is a Windows 10/11 desktop workstation. Version 0.14.0 is already packaged. Python 3.12, PyQt6, local SQLite. It watches public wallets, stores PAPER orders, and draws one-minute candles when a mint has a public pool. PAPER fills are simulated and are never signed or broadcast. LIVE trading is disabled and must stay disabled until a separate, explicit authorization in this contract. Wallet copy is already in the strategy list and is turned off. The current reason is: “Signatures are unclassified, so a copy cannot choose buy or sell.” The missing piece is a decoded swap. This contract makes copy trading production-ready. Do not replace the kernel, the local database, or the fail-closed default. What to shi...

I maintain several live databases that generate a steady stream of purely numerical records—transaction totals, sensor readings, and performance metrics. The raw pulls already sit in secure tables; what I need now is a sharp pair of eyes (and ideally a few smart scripts) to make sure every figure is trustworthy before it feeds our reporting pipeline. Your focus will be end-to-end validation rather than manual typing. You’ll connect to the databases remotely, run consistency checks, flag outliers, trace discrepancies back to source tables, and document any corrections you make. If you prefer working in SQL, Python (pandas), or even a robust Excel environment linked through ODBC, that is perfect; the key is delivering a clean, fully audited dataset that reconciles against the or...

I have a batch of unstructured PDF documents and want every piece of text inside them pulled out and inserted into an SQL database. I do not need the original layout, fonts, or styling—just clean, plain-text content mapped to sensible fields (e.g., file name, page number, extracted text). Your task is to create a repeatable workflow or script that: • Reads each PDF, handles multipage files, and copes gracefully with occasional scan-quality variations. • Outputs the raw text into an SQL-ready structure and populates a database I can query immediately after the job is done (MySQL or PostgreSQL are both fine—I’ll match whatever you choose). • Includes clear setup instructions so I can run the process again on new PDFs without extra help. Accuracy o...

I’m looking for a hands-on Quality Engineer who can sit with our team in Tampa and jump straight into day-to-day support on a large finance platform. Your focus will be functional testing and quick troubleshooting, so you’ll spend most of your time writing and refining SQL queries, scripting in Python, validating business rules, and helping analysts reproduce and fix issues as they arise. On a typical day you’ll: • Design and execute functional test cases against new and existing features. • Craft clean, efficient SQL queries to pull data, verify results, and investigate defects. • Use Python to automate repetitive checks or to parse and compare large data sets. • Log clear, concise defects and re-test fixes in coordination with developers and b...

My application suddenly stopped reaching its underlying database and any direct connection attempt times out or throws generic “unable to access database” errors. Credentials have not changed and the server process appears to be running, so I suspect something deeper—possibly configuration, permission conflicts, or corruption—but I need fresh eyes to pinpoint and resolve it quickly. You will start by investigating the connection path end-to-end, identify the exact obstacle, then apply the safest fix to restore full read/write access without data loss. Please document the steps you take and any changes you make so I can keep the system stable going forward. To jump in, let me know which diagnostic checks you would run first and any information you need from me (log...
