Senior fullstack engineer, 11+ years (mostly Node / TypeScript; 3 years Go), 4+ years as Tech Lead / CTO across remote-distributed teams. Shipped the first alpha of Sophia Forge solo in ~2 months — a local-first desktop game production app (Electron + NestJS + React) with 5,000+ tests across unit, e2e, and Playwright layers, 30 plugins, a bidirectional Unreal Engine 5 C++ integration, and an MCP-based AI surface. I work AI-native: I direct AI coding agents (Claude Code) on production code, gated by tests, typed contracts, and an LLM-as-judge step. Prior production work includes the UK Parliament real-time captioning platform and multi-provider speech-to-text systems (Twilio, Rev.ai, Deepgram, AssemblyAI). Open to: senior fullstack contract / fractional engagements (immediate availability) or full-time roles where remote-from-Brazil works.
