I write about what I learn and build. Most of my posts focus on reinforcement learning, from policy gradients and actor-critic methods to stock-prediction experiments. I also write about quantum computing, algorithms, and coding problems.

I built this customer-facing reservation system for Stellar Kendo Dojo in Taichung, including the backend. Visitors can learn about the dojo and its classes, choose an instructor, select an available lesson time, and submit their information for a trial session. The site also brings together the dojo’s teaching approach, pricing, contact details, and location in one place.
