About Me

I'm Sergio García, a computer engineer. I started coding small games in Python back in high school, earned my Computer Engineering degree at UCLM, and discovered web development through The Odin Project. My bachelor's thesis was a web application that scored a 9 out of 10, confirming my passion for building solutions with code.

I focus on building internal tools, automating workflows, and designing systems so development teams can focus on shipping products. If a problem can be solved with code, I solve it. And if it means learning something new (cloud, distributed systems, infrastructure), even better.

Today, I work at Zennio, where I've built internal tools from scratch using JavaScript and TypeScript, designed CI/CD pipelines, integrated a suite of 200+ automated tests, and incorporated monitoring solutions with Grafana and Prometheus. I'm currently diving deeper into software architecture and distributed systems to continue driving technical value.
