Background

The Client

A U.S. EdTech founder wanted to build a mobile-first app that helps busy parents manage school communications. Their challenges were clear:

The Challenge

No CTO or internal engineering resources

Parents missing deadlines and activities

Tight timeline + limited budget

Needed Google OAuth, Gmail API, Calendar Sync, and AI classification—but no technical expertise

The Solution

They came to me for Fractional CTO leadership + end-to-end delivery. I designed and built the full product architecture and MVP, covering strategy, engineering, and delivery.
