Joel Deon Dsouza Founder | Coder | Athlete
Hi wanderer, I’m Joel, founder of problems, solver of problems.
A full-stack developer, founder, and athlete based in Berlin. I enjoy turning ideas into products, experimenting with new technologies, and building things that solve real problems.
I’m the creator of JistScript, a TypeScript-based scripting language designed for data-centric applications, with a focus on powerful and flexible data processing.
I’m also the founder of Jobell, Illu, and a few projects currently brewing behind the scenes. When I’m not coding or building companies, you’ll probably find me competing in one of the various sports I enjoy.
In short: I build, I experiment, I compete and occasionally wonder why I started another project.
