What I'm looking for

I seek frontend or software engineering roles focused on React/Angular, performance and accessibility, collaborative teams, test-driven workflows, and opportunities to drive measurable product improvements.

I am a frontend developer and software engineer with four years of experience building fast, scalable, and user-friendly web applications using React, Angular, and modern UI frameworks. I focus on performance optimization, accessibility, and maintainable state management with Redux and RTK Query.

At Twazn, a Bahrain-based fintech, I led a codebase transition from React to Angular that increased development speed by 30% and reduced bugs by 25%, implemented 100+ unit tests to reach 90% coverage, and built an admin panel that improved efficiency and reduced task times. I also built responsive, high-performance interfaces for fitness and publishing products, accelerating launches and improving user engagement and SEO.

I bring a collaborative, test-driven approach, strong troubleshooting skills, and a record of measurable impact on reliability, speed, and user experience. I enjoy working cross-functionally to deliver production-ready features and drive continuous improvement.
