DURA
An open-source learning platform that runs from a first click to engineering leadership. Fifteen phases, 539 lessons, 3,500+ hours — mapped to ACM CS2023, SWEBOK v4, and SFIA 9. Mastery-gated so progress is earned. FSRS spaced repetition tuned to the forgetting curve. Offline-first: progress lives on-device, works with no connection. Five specialty tracks reach into embedded, hardware verification, quant/HFT, robotics, and manufacturing. AGPLv3. Free forever, first lesson to last.

Turblu
Technical cofounder, automotive sports infrastructure. Under NDA. The work is automation: taking manual, error-prone processes and making them run themselves. Happy to discuss the engineering approach in conversation.
