About

A researcher who has made recognizing and modeling human action from video the research theme of a lifetime. From surgical footage to everyday motion — I analyze movement in images. I now also work as a freelancer, delivering projects for major manufacturers across action recognition and anomaly detection from video, forecasting models for time-series data, and AI pipeline design powered by LLMs and VLMs. Bridging research and engineering, I take projects all the way from problem analysis to system implementation.

TaskMandala - See how your tasks connect, not just what's next

TaskMandala is a task manager that combines a kanban board and a mind map of the same data, kept in sync in real time. Drag a card on your board and its node moves on the map. Connect two ideas on the map and the relationship shows up on your board instantly. No more guessing which tasks are related or why something matters — see the full picture without losing the detail of due dates, status, and priority. Built for solo developers and small teams who think in both lists and networks.
