Housebook is a construction documentation platform I co-founded. As a shareholder and lead developer, I built and maintained the product over eight years, from initial concept to a mature platform with thousands of users.

Android App

The mobile app lets construction professionals document defects on-site -- capturing photos, adding descriptions, and pinning issues to floor plans directly from their phone or tablet. Originally written in Java, I later migrated the codebase to Kotlin. The app surpassed 5,000 downloads on the Google Play Store.

Housebook Control

All data collected on-site syncs to Housebook Control, the web-based management panel. I co-developed this frontend using Vue, providing project managers with an overview of all documented issues, export functionality, and collaboration features across teams.

Long-Term Commitment

Spanning 2016 to 2024, this was a long-running project that evolved alongside changes in Android development, construction industry needs, and the growth of the user base.
