What I'm looking for

I seek a senior front-end role where I can build scalable, high-performance web apps, lead modern UI/UX work, and collaboratively improve product quality and architecture.

I am a Senior Front-End Developer with five years of experience building high-performance, responsive web applications using React.js, Next.js, TypeScript, Material UI and modern front-end patterns.

I have contributed to large-scale HR systems, subscription and billing modules, design systems, and major Angular migrations, and I have built dashboards, PWAs, real-time features, and complex integrations (SADAD, Qoyod, Moqeem, Mudad, Socket.io, SIP.js).

I deliver maintainable, testable solutions, optimize performance and UX, and collaborate effectively across teams to drive client satisfaction and business outcomes.
