VV Field App — Mobile Field Operations & ERP Integration

Application and integration

The application uses a React web frontend with a Capacitor Android shell and a Cloudflare backend connected to ERPNext. My work connects field workflows to ERP services and improves the reliability of authentication, data access, and delivery.

My contribution

• ERP OAuth/OpenID sign-in, API integration, and employee-aware write behavior.
• Township/project aggregation and construction/manpower workflow integration.
• Android push notifications and remote application-version checks.
• Production configuration diagnostics, API error logging, and contract-version validation.

Release engineering

I also worked on a coordinated ERP contract and production-hardening proposal. Implementation and release preparation are distinct from production activation; this case study does not claim that every proposed release feature shipped.
