What I'm looking for

I’m looking for a team where I can own frontend architecture for complex, high-traffic products—especially Micro Frontends—while leveraging AI-assisted tooling, strong testing, and accessible UX to ship faster without losing quality.

I’m a Senior Frontend Engineer with 5 years of experience building complex React applications and Micro Frontend architectures. As a core developer on a high-traffic hotel booking page at TUI, I designed the integration layer that enabled 10+ independent teams to ship booking UI without cross-team coordination.

I focus on scalable architecture and reliable delivery. I built and maintained micro-frontend integration contracts (public contracts, accepted inputs, emitted events, and lifecycle behaviour), created a central “virtual cart” as a single source of truth, and contributed BFF layers to integrate backend services.

I’m also rigorous about quality and accessibility. I defined and implemented WCAG 2.2 AAA (ARIA) accessibility across complex booking flows, improved confidence with strong test automation (Jest, Playwright, Cypress, and React Testing Library), and integrated AI-assisted tooling deeply into my workflow to accelerate delivery and improve code quality.
