Hi, I'm Tommie πŸ‘‹

Updated: 2026-05-02

  • AI Coding

    • Claude Code lets me build apps I'd previously found too tedious / had been unable to build. This is the most fun I've ever had as a programmer.

  • My Theme

    • Real-time web sites
      • Currently building an MMO (tommieChat).
    • Soft-FPGA
      • A technology I propose: convert Verilog source to C++ via Verilator, then run on microcontrollers.

  • Analog circuits (learning)

    • Interested in RF circuits.
    • Love simulating with LTspice.
    • Goal: build my own RF transceiver from a homebrew circuit.

  • Certifications

  • Languages

    • English: I can read IT technical books in English. Daily conversation is OK, but business-level may still be tough.

πŸ›  Recent Projects

  • tommieChat β€” A 3D MMO chat running in the browser (Babylon.js + Nakama server). Inspired by the once-popular Ameba Pigg
