Sengdao Inthavong

Hi, I'm Sengdao! I'm a computer scientist and software engineer at Expedia, passionate about designing systems and crafting user experiences that empower customers and clients. I have my BS and MS in Computer Science from Northwestern University, where I focused on human-computer interaction and software development.

I've played chess competitively since I was a kid. I won the IESA State Championship in middle school, competed at the USCF National High School Championship, and eventually founded the Raburn Series Premier League, an 8-board league on chess.com that brought together scholastic players from across the country, attracting nationally titled players.
