Hi, I'm Tomislav — cloud architect and consultant in Miami, Florida. 🌴
I build practical generative AI applications — document processing, search, and complex business workflows — and I spend most of my time on the systems around the models: durable orchestration, distributed services, and cloud infrastructure, mostly on Azure. In a previous arc I co-founded Trinsic and spent years deep in decentralized identity and applied cryptography, writing a fair amount of the open-source plumbing along the way.

My website is a small operating system. It has draggable windows, a terminal, a web browser, a trash can (empty), and a handwriting notepad with a desk buddy named Inky. It even works with JavaScript turned off — it boots into "safe mode", grudgingly.
