Hi there, I'm Duzy Chan 👋

"I code for fun and fund, do the right."

I am a Senior Software Engineer and the technical founder of ExtBit LLC. With over 15 years of experience across embedded systems, backend infrastructure, and Web3, I balance my time between open-source contributions and private consulting.

🌍 Open Source & Collaboration

  • I actively build and contribute to open-source software, developing independent tools and patching projects I rely on.
  • I accept sponsorships to collaborate on projects where we share a common interest.

💼 Professional Contracting

  • I provide custom software development, technical consulting, and systemic maintenance for clients worldwide.
  • I specialize in dropping into existing codebases to diagnose, refine, and elevate systems.

💻 Core Tech Stack

  • Languages: C++, Golang, C, Java
  • Environments & Tools: Linux, Emacs, GStreamer, Android (JNI), mac OS
  • Domains: Backend Infrastructure, Custom Developer Tooling, Blockchain/Web3
