Perumdam Mobile
Customer service app for Perumdam Lawu Tirta Magetan utility customers to view billing history, submit categorized complaints with photos, and track resolution status.
J-KOPI (Jember Kota Pintar)
Citizen-facing smart city mobile app for Jember Regency's Dinas Komunikasi dan Informatika (Diskominfo), aggregating government news, service directories, complaint routing, and event calendars.
Outcomes
- Centralized multiple local-government information and service flows into one citizen-facing mobile app.
- Built a complaint routing engine that directs citizen reports to the correct government department by complaint type, with status updates visible to submitters.
- Implemented aggressive caching, lazy image loading, and offline support for previously loaded content to keep the app usable on low-end devices with limited data plans.
- Simplified navigation in a second iteration after user testing revealed non-tech-savvy citizens struggled to locate priority services.
