Hash Code was an annual programming event where teams of students and developers solved one problem inspired by software engineering at Google. The 2021 edition had over 128 000 registered participants and hundreds of hubs around the world.
Hash Code was my community contribution side project at work. I co-created Hash Code @ Google France in 2014 and I was the Tech Lead of the volunteer engineering team that run the competitions for its 9 annual editions (2014–2022).
