About

Professional summary

I am a Lead / Senior Full-Stack Engineer with more than nine years of experience building scalable, high-performance web applications. My primary stack is TypeScript, React, and Node.js, and I have worked across frontend architecture, backend APIs, testing, and delivery automation.

I have held engineering roles at Yandex, Squire, Arrival, Tinkoff, Uptick, and Acronis. My experience includes fintech, AI-powered products, EV manufacturing dashboards, CRM systems, SaaS platforms, and booking solutions.

I specialize in designing maintainable frontend platforms, including micro-frontend architectures and reusable UI libraries. I focus on improving application performance, reducing delivery time, and enabling teams to deploy independently.

I have led frontend and full-stack teams, mentored engineers, supported hiring, and translated business goals into technical roadmaps. I enjoy establishing practical engineering standards around code review, linting, testing, and CI/CD.

I have delivered measurable results, including reducing initial load time by 20%, cutting release time by 75%, reducing production defects by 30%, and increasing AI generation engagement by 50%. I am currently focused on applying AI to improve developer experience, productivity, time-to-market, and developer satisfaction.
