Software Engineer

Code.

I love the work of bridging old systems and new technology — from Visual Studio 6.0 to AI-driven development, I've lived through several eras of how software gets made.

Principles

Engineering principles

  • 01

    Developers can experiment with more ideas, faster, when AI is in the loop.

  • 02

    Tests start from a question — what do we need to guarantee? — not from a number.

  • 03

    Legacy migration is feature understanding, risk management, incremental change, and team communication, not just code translation.

  • 04

    Soft on people, hard on principles.
