Hanneli (@hannelita) is a developer addicted to code, learn new programming languages, blow capacitors, do some C programming and commit useful (or not) code for random Open Source Projects that she finds at Github. She tries to help the community by writing blog posts and organising meetups about NoSQL, programming languages and Math/Physics/Science. She also likes Math, Lego, dogs, hardware, and [much] coffee.
