Profile

  • Senior Frontend Software Engineer with 8+ years of experience building and owning large-scale SaaS platforms in enterprise HR-tech — including sole ownership of a multi-tenant system used by 5,000+ employers and millions of employees across Europe.
  • Deep focus on frontend architecture and system design: long-term architectural ownership, multi-app monorepo structures, design-system-aligned component libraries, and complex domain logic translated into scalable UI systems.
  • Production-scale React and TypeScript practitioner — Nx monorepos, Redux Toolkit, CI/CD pipelines, E2E test coverage, and multi-language platforms shipped and maintained in live enterprise environments.
  • Works closely with product, design, and backend engineering to drive features end to end — from API design conversations to production-stable delivery.
  • Operates with full technical autonomy as a frontend owner: sets architecture direction, code quality standards, and engineering practices; uses Claude Code with Cursor daily as part of a modern AI-assisted workflow.

Open to Senior / Staff Frontend roles.
