Questions

Which technology has the most projects?

Knowledge Graphs, with 10 projects, followed by Natural Language Processing (7). Every page here lists its projects, the people who built them and the skills they used.

How are projects grouped by technologies?

Each solution is tagged from what the team actually built and submitted: their description, slides and documents. A page appears once it has at least 3 projects or open challenges.

Is a GenHax challenge an internship or an externship?

It works like an externship: a short, remote team project on a real problem, with mentors. Challenges are free to join and unpaid. Every submitted solution gets a public page you can show to employers and schools.

Can I join a challenge now?

Yes. 3 challenges are open or coming up, starting with Create volunteer management apps for Malagasy nonprofits. Join on your own or with a team; it is free.

Build something like this

Join a team, prove your skills on a real problem and get mentored by people who do this for a living.
