What I'm looking for

I’m looking for a senior role where I can own end-to-end architecture, optimize performance, and strengthen security—while mentoring teams and collaborating cross-functionally to deliver reliable web products across modern and complex domains.

I’m a Senior Frontend & Fullstack Web Developer with 15+ years of experience delivering web applications across fintech, blockchain, embedded systems, and media platforms. I lead projects from initial architecture and planning through deployment, with a consistent focus on performance optimization, seamless migrations, and robust application security.

I build modern, scalable interfaces and reliable backend services, integrating frontend and backend services to streamline data flow and improve responsiveness. In recent work, I achieved 30% faster load times on embedded devices, reduced legacy load times by 20%+, cut manual operations by 40% in a camera management system, and raised blockchain platform code stability and test coverage above 85%, while mentoring developers and aligning cross-functional teams.
