About

I’m a front-end software engineer with 14 years of experience building scalable, reliable web products and administrative applications. I specialize in Angular, React, React-Admin, and TypeScript/JavaScript, and I enjoy working across teams to deliver high-quality experiences with clean architecture, automated testing, and monitoring.

In my roles, I’ve contributed to technical decision-making and refactoring efforts with strong autonomy, collaborating closely with UX, design, backend, and product to ensure the right solutions are delivered. I’m also continuously learning—exploring technologies like Vue.js, Flutter, and Node.js in personal projects to keep improving performance, quality, and user experience.
