Open to hard, interesting work worldwide
I design products and write the code for them. Up this street: a page that sells a gas detector on its weight, an archery game from the Odyssey, and nine handbooks I wrote for my olympiad students. The astronaut is the one from their covers.

Open to hard, interesting work worldwide.
I taught olympiad physics for four years; my students won three IPhO golds and a silver. Then I joined a gas-detection distributor and had four months to learn the field from nothing. In 2026 my team of four was first of 373 Taiwan teams on the Stage 2-1 leaderboard of WorldQuant's IQC, and I started sending fixes to open-source projects: 65 merged so far, 14 of them into NVIDIA NeMo.
