Featured work

Real-time soccer video analysis. Fine-tuned YOLOv8 finds players, ball, and referee. ByteTrack follows them across frames. GraphSAGE picks out tactical patterns. Served with FastAPI and tracked in MLflow.

YOLOv8 ByteTrack GraphSAGE FastAPI MLflow DVC

Benchmarks RF-DETR, SAM2, SigLIP, and YOLOv8 on soccer player detection and segmentation, with reproducible experiments.

Claude Code plugins I use every day: a codebase audit that reads only the risky functions, a Hacker News digest, a GitHub trending digest, and an open-source status checker.

Real-time stock pipeline. Kafka streams ticks for 10 tickers, Airflow orchestrates, and a TimescaleDB star schema stores them. Runs with Docker Compose.

Kafka Airflow TimescaleDB Docker

Flights, hotels, cars, deals, and billing as 14 microservices that talk over Kafka, run on Kubernetes, and sit behind a React client.

TypeScript Kafka Kubernetes MongoDB React

More: nobel-dataintelligence (protein stability from molecular vibrations) · contextbox (AI context capture for developers) · voxt (voice-to-clipboard for Linux, in Go) · revolu-idea (multi-agent deep research)


Open source

I fix bugs in tools I use. Merged so far:

In review: Model Context Protocol servers and Python SDK, PostHog, Caddy, DSPy, Modular (Mojo), GitHub MCP Server.
