What I'm looking for

I’m looking for senior frontend roles where I can drive architecture, build component libraries, mentor teams, and deliver tested, scalable Angular applications in fintech or enterprise.

I am a Senior Frontend Engineer with extensive experience designing and implementing Angular-based applications for fintech, banking, public administration, and telecom clients. I have influenced application architecture from early stages, built and expanded internal component libraries, implemented Cypress end-to-end tests, simplified application logic, and optimized frontend performance and UX.

I have led frontend architecture and mentoring activities, conducted code reviews, and delivered production-ready solutions across dashboards, admin backoffices, transaction monitoring systems, A/B testing platforms, and e-commerce/configurator products. My work emphasizes testable, maintainable components, modern tooling, and collaboration to ship reliable user-facing software.
