I build full-stack and distributed systems with a strong focus on scalable backend architecture, local AI, and **developer tooling. I enjoy turning complex problems into clean, tested, and well-documented products.
- 🔭 Currently working on: local AI, edge/serverless architectures, and CLI tools for developers
- 🌱 Deepening my skills in: Rust for systems, on-device LLMs, private model serving
- 💬 Ask me about: Next.js/TypeScript, Supabase/Postgres, Flutter, Rust, embedded/TinyOS
