Turning complex frontend systems,
into maintainable products.

I have worked through large legacy codebases with unclear state sources, confusing data flow, and tightly coupled components. By separating responsibilities with Custom Hooks, TanStack Query, and Zustand, data fetching, caching, and UI state became easier to trace.

I have introduced ESLint, TypeScript checks, Vitest unit tests, and Playwright E2E tests to turn error-prone manual review steps into repeatable verification.

I have handled metadata, sitemap, revalidation, and image optimization for content-heavy sites, balancing search visibility, loading speed, and cache freshness.

I have implemented CSP nonces, authenticated state checks, Route Handler authorization, and DAL layering to keep sensitive logic out of Client Components.
