Computer engineer delivering React/Next web and React Native mobile apps with strong performance focus.

What I'm looking for

I’m looking for a role where I can build React/Next web apps and React Native mobile experiences, take ownership from planning to deployment, and keep improving performance through clean code and database optimization.

I’m a computer engineer with practical experience building web applications, mobile apps, and providing basic technical support. I’m characterized by critical thinking and adaptability, with a clear vision for how the projects I join should evolve.

At GRUPO LA MUNDIAL, I worked as a Development Analyst, strengthening my ability to execute within established performance and deadline standards. I focus on delivering reliable features while keeping the user experience and system behavior in mind.

As a Freelance React Developer, I implemented over 6 full-stack projects end-to-end—from planning and design to deployment—using React, Node.js, and related tooling. I integrated external APIs, implemented user authentication, and improved performance through code refactoring, database query optimization, and caching strategies.

I also improved existing applications’ SQL performance by 30%, resulting in smoother operation and reduced load times. I’m now looking to keep applying my web and mobile development skills while continuing to learn and collaborate effectively.
