Hi, I'm Shifa

I'm a Master's candidate in Data Science at the University of Maryland. I've always been drawn to work that sits between perception and reasoning — systems that have to understand where things are and when they happened before they can say anything useful about them.

Lately that's meant Vision-LLMs and spatio-temporal retrieval, multi-agent systems that turn plain English into running infrastructure, and 3D perception stacks that survive contact with a real field of crops. I turn research ideas into systems that ship, and I'd love to talk to anyone working further along this path.

VISTA

Spatio-temporal RAG for video

A persistent memory layer for frontier models that understands egocentric video — tracking objects, spatial orientation, and temporal context through allocentric heading and scene graphs. Outperformed Gemini 3 Flash and Molmo-2 on spatial-temporal reasoning.
