Hey, I’m Carlos Rosas a backend-focused software engineer with 14+ years of experience, mostly living in the Java ecosystem. I’ve worked on all kinds of projects, from building microservices and integrating APIs to handling big systems in fintech and e-commerce. I’ve had the chance to work with awesome teams at places like WildFork, Bitso, SkyTouch, and Globant, always trying to keep things clean, scalable, and maintainable.
I’m really into tools like Spring Boot, Micronaut, AWS, Docker, and Redis, and I love learning new stuff to keep things fresh. Whether I’m optimizing performance, setting up cloud infrastructure, or helping teammates level up, I try to bring curiosity and a solid work ethic to everything I do. If you’re into clean code, good coffee, and geeking out over software architecture, we’ll probably get along.

My Interests
I’m drawn to places where nature, culture, and memory intersect—cenotes, coastal landscapes, archaeological sites. My interest lies in the quiet presence of these spaces and the stories they hold. Influenced by auteur cinema, I document with intention, seeking frames that reflect atmosphere and meaning. Salsa dancing offers a counterbalance—an embodied expression of rhythm and connection. Whether exploring ancient ruins or watching light shift across the sea, I move through the world with curiosity and purpose, guided by a deep appreciation for silence, movement, and the narratives in between.
