01 ⁄ ABOUT

The short version.

Frontend Developer with 5+ years of experience building high-performance React/TypeScript interfaces in multi-team consulting environments. I have worked on decoupled architectures — migrating platforms from monolith to independent services, building reusable components consumed across multiple flows, and integrating frontends with API middleware layers without direct access to core services. I manage local state in isolation, without leaking business logic into the presentation layer. I care about performance, accessibility, and the kind of code quality that scales well in large teams.
