Field notes

I work at the seam between intent and infrastructure.

Senior Software Architect with 13+ years of experience designing distributed systems, AI native platforms, and developer tooling at scale. Active open source contributor to Prisma, NestJS, Qdrant, LanceDB, Tauri, and 20+ other projects spanning Rust, TypeScript, and Python ecosystems. Currently leading engineering at ClickGUARD, shaping REWA's cross platform rent and rewards architecture, and architecting AI driven products for early stage startups. I specialize in event driven architectures, mobile to backend platforms, vector search infrastructure, and resilient systems that handle millions of daily transactions. I ship code that matters in production, not in demos.
