Description

I build and ship production web applications end-to-end, with a frontend focus. 4+ years working across SaaS, fintech, and agency projects.

Recent work includes leading a Next.js App Router migration that cut load times by 60%, and architecting a standardized data layer that reduced frontend-backend friction significantly.

I work with TypeScript, React, Next.js, NestJS, and PostgreSQL daily. Fluent with AI-assisted development (Claude Code, Cursor) which lets me move faster without cutting corners.
