About

I'm Saurabh Rai, founder of Zyvrus Private Limited and a full-stack software engineer. I design, build and ship products end to end: data models and APIs, interfaces, infrastructure and launch.

My work spans SaaS products, games, developer tools and open-source software, built with TypeScript, Go and Python across web, backend and cloud.

Engineering philosophy

  • Ship complete products. A working product in people's hands teaches more than any roadmap.
  • Treat the stack as one system. Schema, API, interface and deployment are designed together, not handed off.
  • Keep the infrastructure boring. Typed code, proven databases and simple architecture leave room for the product to be interesting.
  • Open source where it builds trust. Developer tools should be inspectable, so I publish them openly.

Featured Open Source

TetherTrace running a YAML test on a real Android phone over Wi-Fi

Open-source Android testing toolkit over Wi-Fi, with MCP integration and automated testing.

MIT License TypeScript Android MCP Server

  • Installs and tests an Android app on a real phone over Wi-Fi by speaking the ADB protocol directly. No adb binary or Android SDK required.
  • Explores app screens, catches crashes and freezes, and writes an HTML report with screenshots and logs.
  • Runs YAML test flows from the command line, with optional screen recording.
  • Includes an MCP server that gives AI clients such as Claude Code and Codex control of the phone: screenshots, UI tree, tap, type, install, logs and test runs.
