I'm Ferryal Fajar, a Senior Frontend Engineer with 7+ years crafting exceptional user interfaces. I specialize in React and TypeScript, bringing designs to life with pixel-perfect precision.
From component architecture to Core Web Vitals optimization, I obsess over the details that separate a good UI from a great one.
Hooks, context, concurrent features, performance patterns, and testing. I build React applications that scale to enterprise size while staying maintainable and joyful to work in.
Redux, React Query, Zustand — I choose the right state solution for each problem and architect it for long-term maintainability.
Every line typed, every edge case handled. TypeScript expertise across large codebases with complex types, strict configurations, and zero compromise on type safety.
Well-typed code is self-documenting code. It enables confident refactoring, better tooling, and fewer runtime surprises in production.
Core Web Vitals, lazy loading, code splitting, virtualization — I optimize at every level to ensure every user gets the fastest possible experience.
Accessibility is non-negotiable. I implement ARIA correctly, support keyboard navigation, and ensure every user — regardless of ability — has an excellent experience.
Code is a means to an end. I think in terms of user impact and business outcomes, not just technical implementations.
Pixel-perfect UIs, consistent API contracts, comprehensive tests — quality shows in every layer of the stack.
The best products are built by teams. I communicate clearly, review constructively, and mentor where I can.
The web evolves fast. I stay current with the ecosystem and apply new patterns where they genuinely add value.
