Case study · Legacy system modernization
From a 15-year-old Access database to a secure web app
- The problem
- A mechanical subcontractor ran jobs, scheduling and billing on an aging Microsoft Access app with no dashboard, no mobile access and billing that took a full day.
- What I built
- A web app with a live dashboard, a drag-and-drop crew schedule, AIA progress billing, job costing and a mobile app for field crews, in under six weeks.
- Security built in
- Card data removed entirely, each company's data isolated at the database level, multi-factor sign-in and a full audit trail.
