Problem

The waste-collection workflow needed coordinated changes across an existing Android app, backend API, and database.

Implemented app fixes and features while also modifying GraphQL API behavior and database-backed workflows.

Worked in an existing Kotlin Android codebase for field collection workflows.

Fixed bugs and added features across app screens and data flows.

Modified .NET C# GraphQL API behavior deployed on Azure.

Worked with MySQL data used by the operational workflow.

The project connected mobile app delivery with backend changes so operational updates could move through the full stack.

Mobile, API, and database work handled together.

Experience with field-service style business software.

Changes made inside an existing production system.
