About

am a computer engineer and software developer, with a healthy combination of logic, creativity… and coffee. I have worked on projects in the public and private sectors, applying my knowledge of systems, databases, servers, and web development, with a focus on security, quality, and best practices.

I currently work with Go, PostgreSQL, React, Tailwind, JavaScript, and Docker. I also use tools such as Splunk and Grafana for monitoring. Although that is my current stack, I have experience with technologies such as MySQL, Scala, Python, Cloudera, Linux, TypeScript, Flutter, among others.

I enjoy programming, solving problems, and learning new things (for pleasure or necessity). I like to understand data flow, write clear code… and sometimes break it, just to understand it better. I am always exploring promising tools and frameworks, and sometimes I even create my own.

Outside of coding, I value sharing what I know, working as a team, and always keeping in mind the human side behind technology.
