This work encompasses blue sky explorations, full stack building and research with clear intention to learn, innovate and form a point of view.

Evolving Windows for People and Agents

Evolving Windows for People and Agents

Agents are becoming core to how people interact with technology, and I identified the opportunity, innovated, pitched, formed a consensus, and led the design of foundational patterns for agentic collaboration on Windows. From early blue-sky exploration to shipping core patterns for agent presence, interaction, and collaboration, this work defined a new paradigm for human-AI interaction at the OS level.

Recall & Click to Do

Musio

I was tired of choppy screen recordings and hauling every capture into After Effects just to add zooms and pans — so I built the app I wanted. Native on Windows, cinematic out of the box, no account, no cloud. 1,000+ downloads in the first month with zero marketing.
