crowdAI is Fighting for Open Science with Open Data. We run data science challenges where you can help a NGO, give something to important research or just learn the way programmers always have: by reading other's code.
We're always looking for Rails devs to give us a hand, and if that's not you, then we are always open to feature requests, via our GitHub repo.
Want a free crowdAI sticker? Just ask us.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
