About
I’m a senior software developer with a strong background in backend engineering and full-stack systems, including off-chain infrastructure written in TypeScript. I’m particularly interested in building reliable, well-structured systems that support blockchain and crypto products. My strengths include clean system design, functional programming patterns, and taking ownership of features from design through production.
