I guess it's not ENTIRELY a favor since I founded that company but stepped away a few years back and always felt a bit guilty ever since. They certainly weren't expecting me to build it though.
I built it all myself (including the integration with our ordering platform) It was sort of my white whale project that I've always wanted to do but didn't have the chops/time.
The advancements in AI-assisted coding encouraged me to give it a shot though and the results turned out great. It was a heavily supervised vibe-coding project that turned into a production-ready system.
