What I'm looking for

I seek a role where I can lead frontend platform efforts, improve developer experience, scale micro-frontends, and drive performance and CI/CD automation within collaborative teams.

I am a Senior Frontend Engineer with 4+ years of professional experience focused on building and operating Angular-based micro-frontends, shared libraries, and developer tooling for multi-tenant platforms. I own the full lifecycle from stakeholder requirements through CI/CD and production delivery, and I drive performance and reliability improvements across products.

At my current role I evolved a multi-tenant shell app enabling 8+ teams to ship 25+ micro-frontends, built widget SDKs, standardized CI/CD with Nx and caching to reduce pipeline times ~4×, and raised unit test coverage from ~15% to ~80% through Jest and Playwright automation.

I lead design-system work, migrating components to a reusable PrimeNG-based library used across 10+ products, built internal services to surface UI components to AI agents, and introduced monorepo patterns and automated e2e testing to streamline development and delivery.
