ABOUT
Frontend engineer with 4 years of experience, specializing in building scalable architectures and
improving web application performance. I've worked in teams of up to 20 people, contributing both
to greenfield projects and the optimization of existing solutions. Key achievements include
speeding up page load times, enhancing responsive design, implementing SEO improvements,
and integrating with blockchain technologies. I've also set up secure API interactions, integrated
WebSockets, and optimized requests to ensure backend stability under load. My approach is to
write clean, maintainable code and think several steps ahead

SKILLS
Frontend: Next.js, React, TypeScript, Zustand, MobX, Redux, RTK Query, Tailwind CSS, Stitches,
SCSS, CSS, MUI, Ant, Webpack, Git, GitLab, WebSocket, GraphQL, JWT, Web3
Backend: Node.js, Nest, Express, PostgreSQL, MongoDB, Redis, Apollo client, Prisma, Session, JWT

AI
Solo delivery of production EdTech platform vilqo.com (Next.js, NestJS, PostgreSQL, AWS) using
AI agents with strict Clean Architecture governance. Led legacy migration (2018 codebase) to a
modern stack in 12 months; cut daily dev time from 8h to 2h through Cursor, MCP, and CI/CD/test
automation. AI-native workflow — not just a tool, but the core of how I ship software.
