What I'm looking for

I seek front-end roles where I can build accessible, high-performance web apps, work in collaborative teams, and grow technical ownership.

I am a results-driven Front-End Developer with hands-on experience building responsive, user-centric web applications using Angular, React, HTML, CSS, JavaScript, and TypeScript. I focus on performance optimization, cross-browser compatibility, mobile-first development, and applying UI/UX design principles to deliver high-quality interfaces.

At Group10 Technologies I served as the sole UI developer on multiple Angular projects, improving delivery speed and unit test coverage while reducing post-release defects. I have integrated numerous RESTful APIs, implemented modular architectures, and improved code reusability and readability through best practices and collaborative code reviews.

I co-invented a patented voice-based exam app for visually challenged students and continually upgrade my skills with certifications in advanced React, JavaScript, and prompt engineering. I thrive in cross-functional teams, contributing to maintainable, scalable front-end solutions and knowledge sharing.
