F. Konovalov - Frontend Developer CV.

About

As a Senior Frontend Engineer with over a decade of hands-on experience across product companies, hosting providers, digital agencies, and freelance initiatives, I specialize in React and TypeScript to architect scalable UI systems that fuel high-traffic applications in e-commerce, infrastructure tools, and SaaS ecosystems.

My contributions yield tangible results: spearheading performance optimizations that enhance Core Web Vitals and slash latency; engineering reusable component libraries that propel team productivity by 30%; and guiding junior engineers through rigorous code reviews and architectural mentorship. I shape technical roadmaps, cultivate cross-functional synergies, and inform strategic product decisions-crafting intuitive, accessible interfaces that drive user retention and fortify long-term scalability.
