Backend engineering with Go is the specialty. Around that is 7 years of fullstack and mobile work.

I design and build scalable APIs, microservices, and distributed backend systems. A lot of that is gRPC and REST, including fintech and payment infrastructure such as wallets and ledgers. On the web I use React and Next.js. On mobile, Flutter and Swift with SwiftUI. I like owning a system from architecture and API design through implementation, and I use Clean Architecture, Hexagonal Architecture, DDD, and SOLID to structure that work. The products have been in healthtech, AI, social platforms, SaaS, and e-commerce.
