About

Duzy Chan is a Senior Systems Architect, open-source maintainer, and the technical founder of ExtBit LLC.

His software engineering journey began in late 2005. Over nearly two decades of continuous development, his work has evolved from building independent applications to architecting high-throughput backend infrastructure, custom build engines, and decentralized Web3 protocols for global enterprise clients.

Engineering Philosophy & Technical Stack

Rather than sticking to high-level abstractions, Duzy operates at the system level where memory management, concurrency, and execution speed matter most.

  • Core Languages: Daily drivers are C/C++ (C++17/20) and Golang, with extensive work in Rust and Solidity for Web3 protocol environments.
  • Systems Architecture: Specialized in high-concurrency pipelines, custom JIT compilation, low-level socket communications, and zero-trust security.
  • Methodology: Choosing the right tool for the job with an emphasis on code maintainability, clean dependency graphs, and zero-overhead performance.

Workflow & Terminal Native Environment

In an era dominated by heavy graphical interfaces, Duzy remains a dedicated terminal native. He relies on Emacs as his primary environment for writing code, composing Markdown, organizing tasks via Org-mode, and drafting technical documents in LaTeX. This text-based workflow eliminates visual clutter and maintains absolute focus on pure code and logic.

Open-Source & ExtBit LLC

As the creator of Smart (Next-Generation Make Art & Modular Build Engine) and founder of ExtBit LLC, Duzy bridges the gap between open-source tools and enterprise-grade software solutions. Under the company motto—"Extend the bit, protect your data"—he helps startups and B2B clients design privacy-first backends, custom CI/CD pipelines, and robust infrastructure.
