More about me

• I studied in a technical high school in the morning while simultaneously taking the mechatronics technician course at night. I decided to take the technical course in the expectation of knowing if it would really be my area of interest, and luckily, I got it right.

• Furthermore, I've always planned, and do plan, my future. In this way, the idea of taking the control and automation engineering course at one of the most renowned universities in Latin America came to my mind while I was still in elementary school. This way, after completing the technical course and confirming my interest, I've put it into practice and my choices brought me here.

• Throughout my degree, I've always tried to make the most of my educational institution, UNICAMP, so I've also occasionally done a degree in sound engineering, and I've also carried out a lot of undergraduate research. You can see more about this in my CV.

• Currently, I'm a Senior Software Engineer working remotely from Brazil for US-based companies, with fluent English. My focus is the intersection of software engineering and AI/ML, building scalable backend and distributed systems, designing AI agents, and applying LLMs and RAG to solve real-world engineering problems.
