What I'm looking for

I'm looking to build scalable, high-quality web products where I can lead architecture, solve complex frontend challenges, collaborate across teams, and mentor engineers.

I've built large-scale web platforms at Nextcode.Tech, Tango.me, AgileEngine, and EPAM Systems, from multi-brand CMS products to live-streaming features and e-commerce checkout experiences. I lead frontend architecture, ship complex features, and work closely with clients, product, design, and backend teams.

I've reduced checkout time by 30%, cut server requests per user by 50%, improved performance by up to 25%, and resolved Safari streaming animation failures with WebGL. I also mentor engineers, conduct interviews, and prioritize clean architecture, reliable testing, and maintainable code.
