I'm a CTO and founder who still spends most of his time close to the data. At LEAD I lead the engineering and analytics teams behind data platforms for e-commerce, F&B, and construction clients — pipelines, dashboards, and the unglamorous plumbing that makes the dashboards trustworthy. At GRUDA Technologies, my consultancy, I take on the harder ML problems: recommendation engines, behavior modeling, sustainability analytics.

The other half of my week is training. I run AI workshops for engineering teams and business operators — translating the parts of the stack I actually use into something people can carry back into their own work.

This site is where I think out loud. Two long-running threads: a game recommendation journey where I try every approach I can fit on a single GPU, and a "big data foundation" notebook I treat like a textbook I'm writing for my future self. I started writing because I kept forgetting things, and the act of writing forced me to understand them properly.
