ABOUT
Senior Frontend Engineer with 5 years in B2B and enterprise products.
I love TypeScript and Vue/Nuxt, and I also work with React/Next.js.
I value being able to do more than just close tickets — I want to shape the product too: pitch product and UX ideas, weigh in on architecture.
While building, I keep things maintainable through docs, clean code and test coverage. When it's needed, I set up the process for epics and run onboarding.
A fullstack background helps me see the product as a whole — different options, their trade-offs and what they actually cost.

EXPERIENCE
Senior Frontend Engineer
Building B2B products for IT infrastructure. Owned the frontend of a container orchestration platform (Kubernetes). Maintained a secrets management service (Vault) and built supporting apps around these products.
- Led the redesign of the main product to match the new family-wide design system. Set up an Agile workflow for a team of 5: in six months we shipped a refreshed UI, better UX and new features.
- Wrote product docs and built a microfrontend plugin template — onboarding and dev work got much faster.
- Ran a security audit and fixed 500+ high-severity vulnerabilities across the project's packages.
- Contribute to epic breakdowns, code reviews, onboarding, and architecture and UX discussions.
Middle Frontend Engineer
Outsourcing/outstaff studio. Got to work both on improving enterprise systems and launching apps from scratch.
- Shipped three Telegram Mini Apps under one design system. Led the frontend in Waterfall: from spec and architecture sign-off through MVP to handoff to support.
- Tuned LCP, FCP and CLS by ~30% using Lighthouse.
- Pushed SEO up to 100% and wired in Google Analytics.
- Hooked up AWS S3 with pre-signed URLs for media content.
- Built a streaming chat UI for an LLM (SSE, typewriter effect).
- Worked with Lottie animations and built game-style scenarios in CSS and JS.
Junior Fullstack Engineer
University's business-process digitalization team: moving paperwork into strict web forms with consistent data.
- Built a hierarchical table with lazy loading for recursive data — cut LCP by 3 seconds and lightened the client load.
- Under the lead's guidance, designed scalable architecture, databases, backend and frontend for the apps.
- Collected user feedback on fixes and features.
