A developer running a white-labeled e-commerce platform built on Laravel asks for architectural advice on five challenges: scaling under new tenant launches, messy codebase organization, technical debt from rushed code, whether to adopt microservices, and whether DDD is worth pursuing. The author responds with practical guidance: profile performance bottlenecks before scaling, use lightweight documentation and refactoring over diagrams, treat spiked code as debt that must be paid back, adopt microservices only when specific pain points justify the cost, and take only the core naming/language concept from DDD while sticking to Laravel conventions otherwise.
