Rockstar🎓
Top SchoolNazar Koval is a frontend developer from Lviv with over four years of experience crafting high-performance web products for HealthTech, e-commerce and fitness platforms. He specializes in React and TypeScript ecosystems (Next.js, Zustand, TanStack Query) and has a strong track record of improving UX and business metrics—raising registration conversion from 58% to 73% and doubling client data processing speed through UI optimizations. Nazar designs modular, testable frontends and tooling (UI kits, CI/CD, E2E and unit test suites) that shorten time-to-market and reduce regressions, and he led 30+ A/B experiments to drive product growth. He’s pragmatic about debugging—wryly likening it to being the detective and the murderer—which reflects his attention to root causes and monitoring-driven error reduction.
