I am Howard. I build small web products on Cloudflare by myself and write down what breaks.
Two products so far: Sector Pulse, a US sector ETF data dashboard in Chinese, and Usage Guard, a bill watcher for Workers Paid accounts. Both run on Workers, D1 and KV. The ETF pipeline runs on GitHub Actions instead, because a Worker on the free plan gets 10 ms of CPU per request.
The notes on this site only cover things that happened in production: an index I forgot, a meter that moved, a setup I actually ran. The collector I run for my own account is open source on GitHub.
