Senior React & TypeScript Engineer β I build fast, scalable, well-tested frontends for B2B SaaS products.
6+ years turning complex requirements into clean, maintainable UIs. I care about performance, architecture, and writing code that teams can actually build on.
| Layer | Technologies |

| Core | React, TypeScript, Next.js |

- ποΈ Architecture β set up scalable frontend systems from scratch, not just add features to existing ones
- β‘ Performance β load time, bundle size, rendering β I find the bottlenecks and fix them with numbers to prove it
- π§ͺ Testing β built test suites from 0% to 85% coverage; TDD advocate
- π©βπΌ Leadership β led frontend teams, ran code reviews, mentored junior devs
- π§ CI/CD β GitHub Actions pipelines that actually make deployment boring (in the best way)
