I Built a Mock API Platform in 2.5 Months (Django + React + Redis + PostgreSQL)

I built MockMyData.io in 10 weeks - a multi-tenant SaaS that lets developers generate mock REST APIs in seconds. Each project gets its own subdomain, API key, and full CRUD operations. I tackled subdomain routing, multi-tier rate limiting with Redis, smart quota enforcement for free-to-pro downgrades, and 4-layer payload validation. Built with Django REST Framework, React, PostgreSQL, and Redis. Launching on Product Hunt January 14th.
