What I'm looking for

I am seeking a long-term commitment with a strong team where I can deliver lasting product value and drive continuous improvement.

I’m a senior frontend engineer / full-stack developer with 11+ years of commercial experience, most recently leading frontend architecture for multi-tenant SaaS. I bring a product-first mindset: solid delivery, efficient cross-team work, high execution quality, and long-term maintainability.

I lead complex frontend initiatives end to end, owning both technical direction and delivery. I focus on performance, accessibility (WCAG), and developer experience across the entire stack, with type-safe codebases and clear boundaries between layers, backed by unit, component, and end-to-end testing coverage.

I partner closely with backend teams on API contracts, client API generation, authentication, validation, data models, and edge cases—and I’m comfortable stepping into backend work when needed. From design primitives and design systems to pragmatic proof-of-concepts for emerging tech, I communicate clearly with technical and non-technical stakeholders and take ownership through implementation.
