Hello! I'm Rafael, a software engineer passionate about solving problems through code. I’ve contributed to diverse projects, from data analysis to system development, and I also enjoy sharing my knowledge in my blog.
About me
With experience in backend development, data science, and machine learning, I bring a strong analytical foundation shaped by my background in computational physics and involvement in projects like USP’s BINGO initiative. Skilled in Python and Golang, I have contributed to diverse projects that emphasize system design, architecture, and scalable API development, leveraging technology to solve complex challenges.
Beyond coding, I'm an avid reader, writer, and tech enthusiast committed to continuous learning and community engagement. Outside of work, I enjoy staying active, savoring a good cup of coffee, and collaborating on open-source projects. Let’s connect and create impactful solutions together!
