About Me

Crafting Scalable Systems

I'm a Full Stack Engineer with a deep focus on backend development and distributed systems. With 5+ years of professional experience, I've built and maintained complex data pipelines, backend services, and full-stack features at scale.

I hold a Master's in Computer Science from NOVA School of Science and Technology, completed alongside full-time engineering work at iCapital, where I architect solutions for fund administration and analytics platforms.

Outside of engineering, I'm a musician and serve as a Director of a non-profit cultural association, where I help manage events, music classes, and community initiatives. Fluent in Portuguese, English, and Spanish.
