The T7 Workstation — my portfolio site, styled as a retro desktop OS. Boot it at t7m8.com

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.

🍏 Ziva Nutrition tracking through conversation. Describe a meal in Claude or ChatGPT and Ziva resolves it to USDA food data with a full nutrient breakdown.
✍️ Longhand Neural handwriting synthesis for web and mobile. Typed text goes in, expressive human-looking handwriting comes out.
👁️ Argus A self-hosted dashboard for DBOS durable workflows. Point it at Postgres or SQLite and watch your workflows think.
💳 Very Good Wallet A credential wallet where your passkey is the wallet — no seed phrase, no custody, plus BBS selective disclosure and in-browser zero-knowledge proofs.

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.

The T7 terminal window Longhand Notes — a fresh page, Inky awaits dictation
