💼 I'm open to work opportunities. I can help across real-time web, embedded systems, and low-level optimization. If you're interested in collaborating — including productizing any of my projects — feel free to reach out at open.tommie@gmail.com.

• Location

  • Tokyo, Japan

• AI Coding

  • This is the most fun I've ever had as a programmer.

• My Theme

  • Real-time web sites
    • Currently building an MMO (tommieChat).
  • 
    • 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 (Japanese national qualifications)

  • Class 1 Information Processing Certification
    • Equivalent to today's Applied Information Technology Engineer (AP) Exam.
  • Second-class Amateur Radio Operator
    • Haven't opened a station yet (would like to).
  • Currently studying for Denken Class-3 (Japan's Class III Chief Electrical Engineer license).

• Languages

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

• guruguru-avatar — Web app that drives a 2D avatar from webcam head-pose estimation, for live streaming
• soft-fpga — Runs Verilog RTL in the browser via Verilator + Emscripten, visualizing internal signals (T-states, bus cycles, FSM) in real time — something no instruction emulator can show (live demo)
• tommieChat — A 3D MMO chat running in the browser (Babylon.js + Nakama server). Inspired by the once-popular Ameba Pigg
• Reversi UART Protocol — A protocol spec proposal for connecting a custom CPU to a PC over UART
• Soft-FPGA-Reversi — Pure Othello accelerator written in Verilog, run via Verilator on Raspberry Pi Pico 2
• Soft-FPGA-TD4 — 4-bit TD4 CPU written in Verilog, run via Verilator on Raspberry Pi Pico 2
• curve-tracer — Transistor / FET curve tracer

— A technology I developed and propose: convert Verilog source to C++ via Verilator, then run on microcontrollers
