Development Context:
I'm a solopreneur building SaaS products while working full-time as a Product Data professional. This video shows the real, unfiltered process of building a production web app using AI-assisted development.

Key Insight:
Building a SaaS isn't about writing perfect code on the first try. It's about:
Identifying issues
Using tools effectively to solve them
Iterating quickly
Shipping and improving

AI tools let you build and fix bugs faster, but you still need to understand architecture, debug problems, and make product decisions.
