At a glance
- Role
- Full-stack developer at Litecloud PH, built and maintained the system
- Timeline
- 2022 – 2024, from first module to daily multi-branch operation
- Scope
- Fleet, inventory, automated billing, role-based access, cross-branch reporting for three branches
- Constraints
- Replaced spreadsheet + WhatsApp workflows; had to match how staff already worked, not retrain them around a template
The problem
The client ran three branches on spreadsheets and WhatsApp. Inventory drift, billing disputes, and zero visibility into fleet utilisation were eating margin weekly.
The approach
A full-stack web ERP with role-based access, multi-branch inventory, automated billing, and a reporting layer that rolls up across branches. Designed around the way their staff already worked, not around an out-of-the-box template.
