About me in Full Stack Software Engineering

Hi! I'm Maverick Champi, a full stack software engineer with more than 6 years of experience building scalable applications. I specialize in the fintech sector, payment gateways, and high-concurrency products for startups and global agencies.

I graduated with a degree in Computer Science and Information Technology from Cibertec, where my final project was recognized as one of the best in the country. My strength lies in frontend architecture and the design of modular, UX-focused systems, combined with solid backend and cloud capabilities.

When I'm not coding, you'll find me road cycling or researching the blockchain ecosystem.
