Hello There!

I'm Lemine, a Software Engineer, and a FullStack developer, driven by curiosity and passion, these two have led me to discover new changing technologies, and build later innovative and sophisticated ideas.

My journey as a developer started before my graduation since my main focus was on "learning things by doing" and not on reciting boring subjects, started with C programming language, loved it, then i discovered the sparkling magic of Java, but coded too with PHP and others, did my first freelancing in same year, but programming wasn't only my thing, I loved always debating, puzzles (I play Chess, let's play together), sport and games, and to make my knowledge more solid, I started by the end of 2020 writing articles.
