About Me
Software Engineer
Hello! You can call me Hartmann. I am a Software Engineer, mainly working on backend and a bit of artificial intelligence. I love digital experiences that are finely made and beneficial for others.
In 2024, I saw random reels of some guy who, somehow, would always confidently say "I can build that" whenever he saw a website or a game. Sounds like bullsh*t (at that time), but I liked that confidence, so I started learning web development to see if I could pull it off.
Vibecode boomed after that and everyone could build their SaaS in an hour, so AI became a big buzzword. Nonetheless, I leveraged AI to turn data into meaningful insights and solutions. I also do Kaggle competitions, have been winner and finalist, with work accross tabular data, computer vision, NLP, and audio processing.
