Hi I'm Rafael|

Computer Sciences Engineer crafting scalable and modern web applications

About me

I specialize in turning ideas into digital products that perform and can be measured: clear interfaces, optimized user flows, and metrics that demonstrate real impact. I work across both frontend and backend to ensure user experience and business objectives move in the same direction.

I enjoy building products that go beyond working code: tools that simplify processes, support teams and scale with real usage. My approach combines thoughtful engineering with continuous improvement to keep products reliable as they grow.
