What I'm looking for

I’m looking for Agile teams where I can build scalable Angular solutions with clean code, modern UI/UX, and strong performance. I want ownership of frontend architecture, legacy migrations, and delivering reliable, high-quality product experiences.

I’m a Senior Angular Developer with “hover 6 years of expertise” building responsive web applications. I’m driven by “clean code and scalable architectures,” and I focus on Angular, TypeScript, and RxJS to deliver strong user experiences.

I’ve led frontend development and legacy migrations, including upgrading the Angular framework “from legacy versions to Angular 20.” I refactored code to modern standards, improved application stability and maintainability by 40%, reduced technical debt by 35%, and optimized performance using RxJS and efficient state handling.

Across roles, I’ve redesigned frontend architecture to align with modern UI/UX standards—boosting user engagement by 35% and improving maintainability by 45%. I’ve implemented modular routing, API integrations, and lazy loading/code splitting to cut initial load time by 50%, while delivering complete features in Agile sprints with a “100% sprint completion rate.”

I also bring a track record of reliability and team enablement, from maintaining “100% uptime” during production transition to reducing critical bugs post-migration by 50%. I enjoy collaborating cross-functionally, standardizing coding practices, and continuously learning new technologies in Agile environments.
