I’m a Senior Software Engineer with over 4+ years of experience building scalable, high-performance systems across web, cloud, hardware-adjacent and computer-vision–enabled environments.

I work across the full lifecycle — architecture, development, optimization, and delivery — with a strong focus on clean code, system reliability, and maintainability.

Experience in modern frontend, backend, infrastructure, automation, and low-level development. I especially enjoy solving complex problems and designing systems that have real-world impact.

Currently pursuing a Bachelor’s Degree in Computer Engineering (UTFPR).
