Validate before expanding
An MVP should expose whether the core assumption holds—not prove how many features fit.
About Yancy
Make the problem smaller—and the evidence stronger
Independent developer turning real problems into simple, reliable, verifiable software.
From coding-agent handoffs to everyday automation, I build bounded products that stay lean and can be verified firsthand.
I explore developer tools, automation, data products, and real-world problems that can be tested with small prototypes. This site does not present every workspace experiment as a product; an app appears only when its public scope, status, and support route are clear.
SwitchProof is the first public project. It helps developers hand work between AI coding agents while preserving verifiable context, capability dependencies, and test evidence.
Sutie is the second validation project in the public directory. It explores traceable web excerpts, clipboard history, and app-level flows without rewriting standard copy and paste.
Privacy by default
Work that can stay local should stay local; pages that do not need tracking should not carry trackers.
State what is unfinished
A development candidate, an automated test, user acceptance, deployment, and public release are distinct evidence levels.
