I am a Software Engineer with over five years of experience specializing in TypeScript, React, React Native and Expo. I focus on designing robust, modular systems and applying software development best practices and design patterns.

Most recently I led the development of a banking app from scratch, defining a modular mobile architecture (Clean Architecture), building the React Native + Expo codebase, and implementing encryption and secure storage following OWASP guidelines. I also integrated AWS facial recognition and Face Liveness technologies and designed an internet banking system using Next.js.

Previously I maintained and evolved React Native mobile apps and web portals, migrated legacy apps to Expo and rewrote a web portal from Angular to Next.js using SSR and performance optimizations. I have implemented automated testing with Jest and React Testing Library and set up CI/CD pipelines with GitLab and GitHub Actions.

I work collaboratively in cross-functional teams, establish Gitflow and CI/CD automation, participate actively in code reviews, and prioritize security and usability. I seek opportunities to lead architecture, improve delivery pipelines, and build secure, high-quality products that scale.
