About Me

George Sakelaris - Software Engineer & Entrepreneur

Hey there! I'm George (Daniel), a software engineer driven by curiosity and a passion for turning complex ideas into elegant solutions. My journey started with a Computer Science degree from DePaul University and has taken me through everything from machine learning models that predict UFC fights to building enterprise applications.

What really drives me is the intersection of technology and real-world impact. Whether I'm developing a machine learning model with 77% accuracy on fight outcomes or architecting cloud solutions, I'm always asking: "How can this make a meaningful difference?" Outside of coding, you'll find me on the mats training Brazilian Jiu-Jitsu or listening to music.

I founded Telescode LLC to combine my technical expertise with my entrepreneurial spirit - creating solutions that don't just work, but truly solve problems. Every project is a chance to learn something new and push the boundaries of what's possible.
