Experience

Three Bitcoin Trading Bots

The first bot worked, but only for two months while there was a strange situation in the market. The second one was a proof of concept before the third one which I've been working on now for half a year.

I don't want to reveal trading techniques so it won't be as descriptive as I would like.

Project Details:
• Wrote a lot of code, mainly using Python and NumPy.
• Built several scrappers that collected data from APIs, not necessarily directly connected with the Bitcoin market.
• Currently, there are three redundant, autonomic servers scrapping data involving several dozens of gigabytes of gathered raw data.

Simple Compiler of a Simplified Algorithm for a Simple Assembler

This was my attempt at making a compiler for simplified algorithm for a simple artificial assembler. It was maybe not useful but challenging.

Games

I love game development so I've made plenty of simple projects in C++ using SLD, Java using LibGDX, and JavaScript using HTML5 canvas. I was rather interested in the engine and not the level design.

The most interesting thing for me about these projects was the optimization, implementing the physics, and inventing the design patterns.
