Small products, clear jobs.

I’m Bi Quanneng, an independent developer. BIQN is the public home for my work — the products I ship, the tools I keep free, and the code I build in the open.

I work across product design, application development, AI workflows, infrastructure, and distribution — the whole path from an idea to something people can actually use. I prefer small, focused software with a clear job, honest limits, and as little friction as possible.

Some ideas become products. Some stay free. Some are open source. The common thread is practical software built around real work — tools that do one thing well and respect the person using them: no accounts where avoidable, no data collection by default, no features that don’t serve the core workflow.
