I build fast backends, crypto trading bots and AI products end to end: the Go, Rust or Python core, the real-time data behind it, and the dashboard your users see. Proof from real Upwork clients: • Solana sniper and copy-trading bots in Rust, with PumpSwap, Raydium and Meteora DBC support, ~1.3s buys and live dashboards (a repeat client hired me 5 times) • MCP layer that connected an AI agent platform to a production system (this client hired me twice) • Multi-server Go backend with an Android agent (a repeat client hired me 3 times) • Linux desktop version of a content-protection browser, delivered with a 5-star review • ConvertPDFGo, my own SaaS: 42 PDF tools, AI chat with documents, a public REST API and a Go SDK What I build: 📈 Crypto trading bots: sniper and copy-trading bots, wallet tracking, DEX integrations, exchange APIs, WebSockets, backtesting 🤖 AI features: AI agents with tool calling, MCP servers, AI chat over your documents, OpenAI / Claude / Gemini integrations ⚡ Backend: Go, Rust and Python APIs, PostgreSQL, Redis, Docker, low-latency real-time systems 🖥 Frontend & SaaS: Next.js and React dashboards, auth, payments and deployment How I work: ✓ Clear scope agreed in writing before I start ✓ A small first milestone so you see results before committing more ✓ Clean, documented code and a proper handoff Tell me what you're building and I'll reply with a practical plan and timeline.
