Carlos Pinto

Carlos Pinto built OnboardingHub, a production-grade multi-tenant SaaS, almost entirely with Claude Code as his co-developer. Across 727 commits and 38,000+ lines of code over 8 weeks, Claude authored roughly 95% of the code while Carlos focused on architecture and review. What makes his approach special is the architecture-first methodology. Every commit references specific sections of an architecture.md document created before any code was written. It's a blueprint for how solo developers should work with AI coding agents, and it compressed 6 months of work into 8 weeks.
