Message

At Pasha Bank, I’m developing a shared design system and UI library for micro-frontend applications. I’m also creating codemods to help migrate those applications and an n8n and AI pipeline that monitors Sentry logs and handles targeted frontend issues.

At GuavaPay, I built an admin panel and modular CMS, and developed Telegram WebApps with authentication flows and responsive interfaces. I also contributed to wearable payment ring features and enhanced fintech apps, increasing engagement by 45% and improving page load time by 30%.

As a contract Frontend Developer at Vitanur, I developed responsive interfaces and worked on enterprise-grade frontend applications. I also improved accessibility and performance, achieving Lighthouse scores above 90.

I’ve taught modern React and full-stack fundamentals at Code Academy, guiding students through assignments and real-world projects. Across my work, I’ve built frontend and full-stack applications using React, TypeScript, and Node.js.
