Key Engineering Achievements

The engineering decisions and challenges behind this project

Multi-Module Architecture

Challenge

Building a single app that handles diverse home management needs without becoming bloated.

Solution

Designed a modular architecture with independent feature modules (maintenance, expenses, inventory) sharing a common data layer and UI component library via Material UI.

Impact

Each module can be developed and tested independently while maintaining a consistent user experience.

Impact

Sub-100ms query times on dashboard views even with thousands of records.

Developer's Note

Home Manager started as a personal frustration with forgetting when things were last serviced. It evolved into a full platform when I realized how many household operations benefit from simple data tracking. The key lesson: good UX means hiding complexity, not removing it.
