What I'm looking for

I seek front-end or full-stack roles where I can improve performance and accessibility, work in Agile teams, mentor others, and build scalable, maintainable user interfaces.

I am a Front-End Developer with over 5 years of experience building scalable web applications across banking, government, and e-commerce sectors. I prioritize performance, accessibility, and clean, maintainable code.

At CHECK24 I developed and sustained Angular modules and modular UI components using Angular Material and SASS, integrated REST APIs with RxJS, and wrote unit tests with Jasmine/Karma to improve reliability and performance.

Previously, I executed full-stack development for Santander Tecnologia using Angular, .NET C#, and Oracle, and built a React front-end tool to accelerate incident triage for engineering teams. I also contributed to a large government platform at Sinergia Digital, implementing validated web forms and collaborating with back-end teams.

I work well in Agile/SCRUM cross-functional squads, participate in peer reviews, and leverage tools like Git, Bitbucket, Jira, and Confluence to deliver iterative improvements that enhance conversion, usability, and maintainability.
