About Me

About Me

My name is Liam Dondisch. I am a Mexican-American sophomore at Northeastern University's Khoury College of Computer Science, pursuing a combined major in Data Science and Psychology. I am drawn to telling stories through data to power real business solutions, whether that is building infrastructure from scratch or turning messy datasets into something actionable.

I am currently a Junior Analyst at GFG Real Estate Management, where I primarily support the creation of their new data infrastructure. I designed and architected a multi-platform data aggregation system that processes over 1,600 data points weekly across 14 enterprise hotels, pulling from TripAdvisor, Google Maps, Expedia, and Booking.com into a centralized PostgreSQL database with 94 tables and over 698,000 records. I also built a custom sentiment classification engine with a 6-category, 28-subcategory taxonomy that parsed over 350,000 review segments at the sentence level, replacing entirely manual workflows and saving over 20 hours of work weekly.

Outside of work and school, I am a Cruz Azul and Green Bay Packers fan, a big Oasis listener, and a fluent Spanish speaker who grew up in Mexico City. I care about building things that are both technically rigorous and genuinely useful.

I am currently seeking co-op opportunities in data, whether that is engineering, analytics, or machine learning. Feel free to reach out.
