I build backend systems in Go and Java for crypto and fintech.
What I deliver:
- Trading bots (CEX/DEX integration, order execution, signal engines)
- Exchange API integrations (Binance, Polymarket, Bybit WebSocket feeds)
- Microservices architecture (gRPC, Kafka, event-driven)
- REST/WebSocket APIs
- Database design (PostgreSQL, Redis, MongoDB)
- Docker/Kubernetes deployment
I have a live trading bot running on Polymarket right now — 73% win rate, 200+ trades, real money. Not a backtest, not a demo.
5+ years commercial experience. Clean code, tests, documentation
