What I'm looking for

I’m open to remote or international opportunities where I can contribute to complex products, modern architectures, and high-performing teams—using strong Angular, Nx, and NgRx expertise, plus close collaboration with QA and UX to deliver maintainable solutions.

I’m a Senior Front-End Developer with 10+ years of experience building and modernizing scalable web applications across multiple industries. I specialize in Angular (2–16) and modern front-end architectures, with deep expertise in Nx monorepos, NgRx state management, and enterprise-level UI performance.

I’ve led migrations of legacy desktop and Flash-based systems into modern, high-performance web platforms—most notably moving a 10+ year-old desktop call center application to Angular 16 using an Nx monorepo. I focus on code quality and maintainability, implementing unit testing strategies with Jest, Spectator, Karma, and Jasmine, while partnering closely with QA, product owners, and UX designers; I’m also comfortable acting as a technical reference, refining user stories, and mentoring developers.
