I started collecting this list of projects when I was 15 years old and coded just for fun. It's my personal collection of achievements and shows the path I took regarding both software engineering (tech stack) and entrepreneurship. These are mostly toy projects though, for something more serious you may prefer to check my professional experience on LinkedIn.

Publik Investment Engineering S.L.

Jan 2015 - Nov 2017

The foreign exchange market (forex) is the biggest market in the world with more than $5 trillion per day traded. Most of that volume is traded by automated pieces of software or Expert Advisors. So forex is basically a war-zone between trading robots that compete against each other for succulent profits. I decided to try and build my own Expert Advisor initially as a hobby, but I found some success and now I personally invest and accept third-party investments in this amazing world of code and mathematics. Finally, the project led to the foundation of the company Publik Investment Engineering, SL, together with a commercial partner, where we received an investment that exceeded €900,000, with the intention of establishing an Investment Fund. Finally and after unsatisfactory results in 2017, we decided to close, signing nevertheless a positive return of +67% from July 2015 to November 2017. Its presentation page was publik.ie but is no longer available.
