Pocketful is a staged payment and wallet service created using a multi-agent software factory built in BAND. Instead of developing the application directly, I designed a workflow where specialized AI agents collaborate as an engineering team. A Software Architect interprets requirements and delegates work, an implementation agent builds the solution, and an independent Reviewer tests the result, identifies issues, and verifies fixes. The factory developed Pocketful across four progressively more complex stages while preserving functionality from previous stages. The agents handled implementation, testing, concurrency and edge-case analysis, regression testing, and Docker verification. When problems were discovered, work was routed back through the factory for correction and independent re-review. The final result demonstrates not only a working application, but a reusable development process designed around delegation, independent verification, and evidence-based sign-off.

🌎 Online Hackathon | 💻 Online Build: Sept 26 - Oct 5, 2026 A virtual, global hackathon. Build from anywhere in the world. Dark Factory is the official hackathon of WeAreDevelopers World Congress North America, presented by BAND, but you don't need to be in San Jose to take part. For one week, you build a software factory in BAND Desktop: a band of coding agents that plans work, implements it and checks its own results. 🎟️ Bonus for sign-ups: you are eligible for a free ticket to WeAreDevelopers World Congress North America in San Jose (Sep 23–25). If you do go, stop by the BAND booth: a surprise is waiting for you.
