What I'm looking for

I seek frontend roles where I can build performant, user-focused React/Next.js products, lead cross-functional teams, mentor juniors, and drive measurable UX and performance improvements.

I am a detail-oriented frontend web developer with 3+ years building sophisticated web applications and user-centric platforms. I combine a background in Electrical Engineering with practical experience to solve technical challenges and deliver polished user experiences.

I have built responsive, high-performance interfaces using HTML5, CSS3, Tailwind CSS, JavaScript, TypeScript, React.js, and Next.js, and I frequently use UI libraries such as Mantine, Material UI, and ShadCN.

In recent roles I led frontend teams, implemented secure payment and real-time transaction features for a crypto exchange, and developed portfolio and budget management platforms that improved user satisfaction and reduced load times.

I mentor junior developers, collaborate across functions to ensure scalable architectures, and focus on delivering measurable outcomes like increased engagement, faster load times, and cleaner, maintainable code.
