What I'm looking for

I’m looking for a frontend role where I can lead architecture, ship scalable React features with TDD and feature flags, improve CI/CD and monitoring, and collaborate closely with Product and Design to deliver business-focused outcomes.

I’m a Senior Frontend Engineer with 10+ years of experience in React, frontend architecture, and product development. I focus on scalable applications, technical leadership, automation, testing strategies, and cross-functional collaboration to drive engineering excellence and reduce technical debt.

In my recent roles, I’ve applied TDD with “small and safe steps,” used feature flags for production deployments, and built user-facing systems like an AI-assisted chat and navigation using streaming. At Mercadona and Leadtech, I’ve helped create scalable CI/CD pipelines (Jenkins and GitHub Actions), implemented monitoring with Sentry and Elasticsearch, contributed to a universal design system with a mobile-first approach, and mentored engineers through code reviews and shared development workflows.
