Crafting Digital Experiences

Profile Photo

Hi, I’m Sebastian. I’m a software developer who loves building things that actually get used. I started out curious about how technology works, and that curiosity turned into a career focused on creating clean, reliable, and user-friendly applications.

With a strong foundation in both software engineering and data science. Most of my work sits at the intersection of both. I enjoy turning complex ideas into simple, practical solutions. I care a lot about writing code that’s easy to understand, easy to maintain, and built to last.

When I’m not coding, I’m usually experimenting with new tools, contributing to projects, or learning something new just for fun. My goal is to keep getting better at what I do and build software that actually makes a difference.
