Working with python since my second year on college (2011). Started using it with scientific project on Natural Computing field which the goal was running parallel AGs with CUDA (pyCUDA) and OpenCL (pyOpenCL).
I also developed a small memory-footprint middleware (with python) to running python modules on distributed mode over my 8 nodes raspberry pi cluster as my final paper.
Right now i'm focusing on web development which means i spent more time coding with django to deliver amazing web experiences.
Started using this awesome framework on 2014 when i launched my career as freelancer. Never looked back! Django has a flawless architecture/pattern to organize you web application. It's really easy to build a precise roadmap and define deadlines on the early stages of the project, and it's easy to maintain or even switch between apps. Amazing.
I've used to build a ReST API for my first private contract and still using it right now.
Started playing around with it since 2010 (freshman year). Used with greenfoot, slick 2D, and other small libraries. Most of my work was on desktop.
Right now i'm using exclusively for Android development.
I've been learning Java since my 0-day at college but i was not a big fan of using it for desktop nether web applications. But on the end my 3rd year i had to working with android. It was fun i learned a lot of patterns and learned that a lot of the developers don't know what they're doing with it (and that is the reason why there is so much crazy tutorials over the web).
I only returned to Android on 2014 when i launched my freelance career. I'had to developer and Client for the ReST API i was building with Django and the client decide using it. It's was surprisingly easier to working on. A lot of new libraries, new IDE. Good experience. But i still hate java anyway! For that i decide to coding with kotlin too.
To be honest i was very confused at what would git could be doing for me on 2011. Nobody ever heard about it (everyone were into SVN or HG) so nobody ever taught me squat about it. I decide that somehow this would be a important thing in future and started learning by myself as usual from the IT guys.
But was only on 2014 that i had my skills tested up. You can the results over my github or bitbucket.
