ABOUT

Sebastian Linares

Fullstack & AI Developer

Lyon, France

I'm originally from Colombia. I moved to France to pursue my studies in Computer Engineering, and I have been living here for almost five years. I also spent five months in Spain as part of an Erasmus program at UPM in Madrid.

I enjoy building full-stack web projects where I get to shape the whole picture: UI/UX, databases, and services. This interest goes beyond my coursework: I'm involved in student life at INSA, where I started as a member of the Student IT Association, building applications for campus life. I'm now an IT consultant at ETIC, INSA's junior enterprise, working on real projects for real clients. These experiences taught me how to work with clients who don't have a technical background, translating their needs into IT solutions that actually work for them.

My current internship got me interested in AI solutions for businesses: identifying which processes in a company can be improved or automated through AI systems, and designing them using multi-agent architectures, persistent memory, tool use, skills, and RAG, among other techniques.

I speak four languages: Spanish (native), English (C1), French (C1) and Portuguese (B1). I have lived in France, Spain and Colombia, and I love traveling to new places and learning about different cultures.

If I'm not coding, you can find me in the gym, playing football, or reading at the park.
