HADI K.

I build and operate production Python systems — not prototypes. My work is backend services, automation, and API integrations that run 24/7 on Linux cloud infrastructure: FastAPI services, async Telegram bots, scheduled data pipelines, and third-party API integrations with retries, idempotency, structured logging, and health monitoring. I currently run 14 production bots and a live crypto signal platform with a public performance dashboard. A recent project shipped with 106 passing automated tests. I also work daily with AI-generated code (Claude, Gemini, Codex-style models) — reviewing it for hallucinated APIs, plausible-but-wrong logic, and edge-case failures before it reaches production. What I'm good at: making systems that don't silently break. The dangerous failures usually aren't crashes — they're cases where software keeps running while its internal state drifts from reality. I build for reconciliation, auditability, and deterministic behavior. Stack: Python, FastAPI, asyncio, REST APIs, WebSockets, Telegram Bot API, Playwright, SQL/SQLite/PostgreSQL/Supabase, Linux, GCP, DigitalOcean, Supervisor/systemd, Git. Available 15–25 hrs/week, UTC+3, comfortable async with US/EU overlap.
