What I'm looking for

I’m looking for a remote-from-UTC+3 opportunity (full-time, long-term contract, or focused delivery). I want B2B impact, senior ownership across architecture/performance/migrations, and an option for EMEA relocation.

I’m a senior frontend engineer with six years building and modernizing complex B2B product interfaces with React and TypeScript. I work as a hands-on technical lead, taking ownership of performance, migrations in live codebases, product architecture, and zero-to-one delivery.

Currently, I’m building an AI-assisted research platform for scientists—connecting authoring workflows with Monaco-based LaTeX/Typst editing, reliable saves, and auxiliary sources. I also deliver compiled-document review with PDF.js, source-linked compile errors, and resilient failure states, plus an AI research UX with per-message models, reasoning states, token usage, and reusable response actions.

Earlier roles include Smartway (70% faster rendering via list virtualization, HMAC authentication migration, and an embeddable support widget with a ticket-management workspace). At Smart Online Institute, I took an EdTech MVP from an empty repository to production in ~5 months using a Next.js BFF, secure S3 media delivery, GitLab CI/CD, Docker deployment, and Playwright-driven legacy migration; before that, I built and shipped a complete B2B e-commerce system as the sole developer with Nuxt/Vue, Express, and MongoDB.
