Hi, I'm HongYu 👋

I'm a master's student working across infrastructure, full-stack software, and computer vision. I like designing systems from the interface down to the API, data, workers, and deployment. My current research focuses on Sim2Real vision for sports, especially volleyball and basketball. If a tool I want doesn't exist, I often build it.

What I work on

  • Infrastructure & system design: containerized services, networking, storage, CI/CD, Terraform, and distributed task processing—including parallel GPU workers on Kubernetes.
  • Frontend & backend: web and desktop interfaces, APIs, databases, real-time communication, and video workflows.
  • Computer vision & simulation: synthetic data, detection and tracking, pose, camera geometry, multi-camera video, and sports analysis.
  • Tools for my own needs: small apps, CLIs, and developer tools that make a specific workflow easier.

Technologies I've used or explored

I've come across these in projects and experiments. My experience varies by tool, and I'm still learning many of them.

A few public examples

Vision & simulation

  • Volleyball Analysis Engine — detection, tracking, pose, and analysis in a Python / PyTorch / OpenCV / Docker worker.
  • NeuralCourt Basketball — a Unity / C# basketball simulation with GPU-batched character motion and multi-camera monitoring.

Full-stack applications

  • Volleyball Monitoring AI — live annotation and video workflows across Nuxt / Vue / TypeScript, Fastify / GraphQL Yoga / Prisma / PostgreSQL, and Redis / MinIO / WebSocket / FFmpeg / OvenMediaEngine / Traefik.
  • PatentsHub — a desktop application using Electron / Nuxt / Vue / tRPC / Prisma.

Tools I built because I needed them

  • TartUI — a SwiftUI interface for managing Tart images and virtual machines on macOS.
  • k8s-mig-manager — a Bun / TypeScript / Ink CLI for NVIDIA MIG profiles on Kubernetes nodes.
  • Snip — a SwiftUI / yt-dlp / FFmpeg app for downloading and clipping video.
  • Cloudflare Catch-all Mailbox — a searchable inbox API built with Workers / D1 / R2.
  • Nuxt Imperative Modals — a Nuxt / Vue / TypeScript module for opening typed modals from code.

More experiments and projects are on my repositories page.
