Hi, I'm Alex 👋

Senior Frontend Engineer with 9 years of experience. Based in Warsaw, Poland.

What I do

I build production frontends, from greenfield architecture to long-lived codebases. Frontend is my craft, but I work across the stack with Node.js and have hands-on experience in Go and Python.

I use AI tools daily for testing, code review, and product work, and I'm interested in shipping AI as a real product layer - not just a wrapper.

I take on engagements as a senior contributor inside product teams or as the technical owner of a frontend codebase. No management.

Stack

Core: TypeScript · Vue 3 · Nuxt · Node.js · Vitest · Playwright · Cypress Also: React · Astro · Supabase · AWS · Go · Python AI layer: Claude API · Claude Code · LLM workflows · AI-assisted testing Workflow: GitHub Actions · Docker · Cursor

Selected work

  • Torq.io — SaaS security platform (US/Israel). Senior FE on a real-time dashboard. Raised unit test coverage from 10% → 70%, integrated AI-assisted test creation, improved CI/CD and the internal UI library.
  • LoveCrafts — UK e-commerce & social platform. Led legacy → Vue migration. Owned checkout and payments (Apple Pay, Google Pay, regional providers) → 30% conversion lift, 60% lower cloud cost at peak. Multi-brand composable architecture cut new-brand migration to 4 months.
  • OneReach.ai — US SaaS AI orchestration. Serverless apps on AWS, content builder, platform UI library.
  • Vintage Web Production — Built a major Ukrainian bank site and multiple award-winning projects, including a "Site of the Day" winner.

Currently building

GymTempo — Local-first PWA for tracking strength training. Sole technical owner: architecture, frontend, backend, infra, design.
