Full Stack Developer
Senior Software Architecture
Full-stack architect with 8+ years building scalable, high-performance web applications. I design and deliver complete systems across web3, cloud platforms, and full-stack products. The stack is deep: Rust, TypeScript, Solidity on the language side. React, Node, Elysia, Supabase, PostgreSQL, Redis on the infrastructure. Docker, Kubernetes, AWS, GCP for deployment. I choose minimal. I verify with tests. I ship what holds.
I lead engineering teams, establish architecture standards, and translate complex product requirements into clean, maintainable code. I thrive in fast-moving startup environments where ownership, velocity, and clean architecture matter equally.
Artist by training. Engineer by practice. Both inform the work.
