I build production-grade Python systems for clients who need things that actually run — trading bots that survive volatile markets, AI integrations that don’t hallucinate critical fields, and automation that holds up when traffic isn’t synthetic. --- What I do • Trading bots & infrastructure * Crypto: Solana sniper bots, multi-exchange arbitrage, Binance/Bybit futures, BNB Chain monitors * Traditional: IBKR live trading, OANDA execution, day trading automation, news-driven entries * Prediction markets: Kalshi & Polymarket bots * TradingView → broker bridges (webhooks + Python middleware, Docker) • AI-powered tools * GPT-4o / Claude integrations into existing workflows * Multi-tenant SaaS with LLM features (KPI dashboards, automated responses, agent systems) * Discord + Voiceflow integrations, voice/text agent loops * Custom Telegram bots: monitoring, alerts, command UIs, payment flows • TradingView (Pine Script v6) * SMC/ICT indicators (BOS, CHoCH, order blocks, FVG, liquidity) * Strategies, backtesting, alert systems — no repainting tricks • Web & full-stack * Django / DRF multi-tenant SaaS * React (Vite) frontends * PostgreSQL, Redis, Docker, async architectures --- Stack I use daily Python 3.12 · asyncio · aiogram · python-telegram-bot · Django/DRF · FastAPI · Web3.py · Helius · Jupiter · Binance API · IBKR · OANDA · OpenAI / Anthropic SDK · Pine Script v6 · Docker · PostgreSQL · React --- How I work 1. I scope before I quote. If your idea has a fatal flaw — rate limits, MEV exposure, unreliable LLM behavior — you’ll hear it upfront, not on delivery day. 2. Async-first engineering. No blocking calls, no “sleep loop” bots pretending to be scalable systems. 3. Production-ready delivery. Logging, error handling, and a runbook — not just a .py file. 4. Honest fit assessment. If I’m not the right person for the job, I’ll tell you early. --- Based in Warsaw, Poland. Comfortable across EU & US time zones. Fluent in English. Fast turnaround on small projects (1–3 days). Structured discovery for larger systems. --- Send me your idea, repo, or the system that keeps crashing — I’ll respond within 24 hours with whether it’s a fix, refactor, or rebuild, plus a realistic timeline.
