Ruiming Zhao — Prysai AI systems and developer tools

Prysai Lab  ·   Repositories  ·   Core projects

About

I build and inspect AI systems that hold up beyond the demo: agents, retrieval, evaluation, and tool use in real developer workflows.

Current direction

I follow the full agent engineering loop:

  • choose the right model and context
  • connect tools safely and make behavior observable
  • evaluate quality, regressions, and failure modes
  • turn useful experiments into repeatable workflows

The goal is simple: fewer impressive demos, more systems that can be tested, understood, and improved.

Building with Prysai

Prysai is the home for product experiments and practical work around AI systems and developer tools. The emphasis is on small, testable pieces that can be inspected, measured, and reused.

Open-source contributions

Six upstream projects, seven merged pull requests — documentation, packaging, compatibility, performance, privacy, and UX fixes that are now part of other projects.

Project Contribution Merged PRs
MSKazemi/kubeintellect Documented v4 data-handling boundaries and updated the kube-q Homebrew formula with current release resources. #105 · #111
mastra-ai/mastra Fixed CommonJS schema compatibility by bundling the Zod conversion dependencies and adding regression coverage. #21147
squid-protocol/gitgalaxy Replaced manual append loops with extend-based recorder code and resolved the related Ruff performance findings. #1201
abenneto/gandharva Refined README formatting and section headers. #19
seva9523/EvalRepro Added --no-id-preview to suppress sample ID previews while preserving sample and field digests. #12
felladrin/MiniSearch Capped staggered result animations and honored prefers-reduced-motion. #2324

All entries above are public PRs confirmed as merged into their upstream repositories.

Core projects

A compact working set of upstream projects I currently study, use, or contribute to. They are selected for technical leverage, not repository size or star count.

Account star history

This tracks the total stars received by my public repositories over time. It is an account-level view, not the star count of any single project.
