From Zero to Launch: Building MoodFlow in 2 Weeks
The Timeline
Week 1: Foundation
- Set up FastAPI backend
- Integrated DeepSeek API
- Built the Quiz Generator (most complex tool)
- Created basic UI
Week 2: Expansion & Polish
- Added TikTok Script Generator
- Added E-Commerce Copy tool
- Built Auto Reply system
- Added Education Quiz tool
- Multi-language support
- User auth & credit system
Technical Decisions
Why Not Django?
Django is great, but overkill for this. FastAPI's async nature is better for AI API calls.
Why Not React?
The MVP needed to be lightweight. Server-rendered HTML with vanilla JS keeps things fast and simple.
Why Not PostgreSQL?
SQLite is perfect for a solo project at this stage. Zero configuration, zero maintenance.
Lessons Learned
- Start with the hardest feature first (Quiz Generator)
- Test in all languages early – some prompts work in English but fail in Thai
- Keep the tech stack simple – complexity kills momentum
