About

Senior Frontend Engineer and Tech Lead with 7+ years delivering high-performance, scalable web platforms. I care deeply about UI quality, accessibility and resilient architecture.

My toolkit spans React + TypeScript on the frontend and API integrations with scalable backends (NestJS). Comfortable with containers and orchestration (Docker, Kubernetes) in production environments.

As a technical leader, I set engineering standards, mentor teams and ensure code quality and delivery reliability.
