About
I'm building Atta Labs, an applied-AI ecosystem where multiple applications share a Bun, TypeScript, and Turborepo agent infrastructure. I own the architecture end to end, including multi-LLM routing, LangGraph orchestration, YAML-defined agent flows, MCP hosting, BYOK encryption, and evaluation frameworks.
At Game7, I architected a multi-tenant Web3 gaming platform and designed multi-agent content generation workflows that balanced model capability, speed, cost, and output quality. I also created an OpenAPI-to-component-props pipeline, AI-assisted development practices with human review gates, and real-time multiplayer features.
Previously, I led frontend architecture at Elixir Games and built its cross-platform Web3 game launcher for Windows, Linux, and macOS. My work also spans React and GraphQL platforms at Conferize, SaaS interfaces at Sherpany, full-stack client delivery, travel technology at Amadeus, and KNX embedded firmware at Zennio.
I direct agents rather than defer to them, and I don't ship code I don't fully understand. I care about deterministic checks, explicit contracts, provenance, and keeping codebases honest while AI writes more of the implementation.
