I build practical AI systems that move from research notebooks to real production environments.

The background shows a playful object-tracking demo: moving objects get detection boxes and IDs, and crossings of a counting line are tallied, like the counting systems described below.

About

From research notebooks to production.

My work focuses on computer vision, multi-object tracking, segmentation, legal AI / RAG systems, remote-sensing workflows, and backend infrastructure for ML products.

I enjoy designing end-to-end pipelines: from data ingestion, model experimentation, retrieval systems, and evaluation to FastAPI services, Docker/Kubernetes deployments, observability, and production iteration.

I like building systems that are not only accurate, but also observable, maintainable, deployable, and usable.
