As a Senior Frontend Developer, I build performant, user-friendly web applications. I have expertise in JavaScript/TypeScript, React/Next.js, MobX/Redux, Tailwind/SCSS, Webpack/Vite, and more. I’ve successfully developed customer-facing dashboards with real-time chat, and created complex, dynamic forms, all while ensuring high-quality code through testing with tools like Jest/Vitest and React Testing Library (RTL).I’m passionate about expanding my skill set in Node.js and React Native, and I enjoy mentoring junior developers to foster collaboration within teams. I’m always looking for opportunities to innovate and take on leadership roles, driving both personal growth and project success.
