The problem

Test whether a product idea could go from concept to a real, operable platform in days rather than months.

How I approached it

  1. A written goal and definition of done
  2. An architect agent planned the work in waves; builder agents delivered each wave; a completeness review closed it

What was built

  • Web app and APIs
  • CI/CD and observability
  • Brand refresh
  • Onboarding and accounts epic

Stack

  • Next.js
  • .NET 10
  • Azure Front Door
  • Container Apps Jobs

Outcomes

  • A platform ready for real users
  • Architecture decisions and runbooks written as it went
