[ about; ]
I'm Jakub Halbrštát, a 19-year-old developer from Pardubice.
I finished Delta SŠIE in 2026, a four-year school of information technology and economics, where I also studied design, photography and marketing. Since then, and for two years before it, I've built my own products: a voice-based English learning app, a creator platform, trading tools, Instagram automation and a brand of my own.
I like hard problems. When something catches my interest, I go deep: I taught myself market structure well enough to train a neural network on a terabyte of data, and I once learned massage properly, from deep tissue to kinesiotaping, just because I wanted to do it right.
I'd rather work with clients directly, but I'm open to a job too.
