I'm a software engineer at Velocidi (https://www.velocidi.com/)[1] an online advertisement company focused on high performance, distributed artificial intelligence systems.

I'm mostly interested in artificial intelligence, distributed systems, game development and computer graphics.In my daily job I mostly work in our forecasting system, although I also worked in recommender systems and real-time distributed services in Scala.

During my free time, I love to enter hackatons and code jams. Here's some of my entries:

• Pixels Camp:
• Pixels Camp 2017 - Pixels-WiFi (7th Place \o/)
• Pixels Camp 2016 - PepeDex (We ended up not presenting the project, but it was pretty dank)
• Ludum Dare:
• Ludum Dare #27 - Rewind and Run (https://github.com/JD557/Rewind-and-Run)
• Ludum Dare #34 - Waku Waku Buffet (https://github.com/JD557/WakuWakuBuffet)
• Ludum Dare #37 - Roombat (https://github.com/JD557/Roombat)
• PLT Games December 2012 - Wolf (https://github.com/JD557/Wolf)
• Codebits 2009 - 2014 (I have no idea where are those repos, though…)

I also gave a lightning about Chip-8 on the last edition of Pixels camp. Check it out here: https://joaocosta.eu/Talks/Chip8

Finally, during my master thesis I developed some novel classification algorithms for ordinal classification and implemented them as a Weka plugin.If you are interested in that sort of stuff, feel free to checkout http://gitxiv.com/posts/2hZorJHPcKZtjfrS6/ensemble-methods-in-ordinal-data-classification
