Internal platform engineering across backend services, data workflows, and operational tooling.
- Designed and maintained backend services in C# (.NET Core) with SQL Server persistence, exposing REST and GraphQL APIs for internal operational workflows.
- Built a React and TypeScript admin interface for driver management, job tracking, and day-to-day operations, with attention to predictable data entry and clear state transitions.
- Implemented workflow automation around repeated operational steps, reducing manual coordination and making routine processes easier to verify.
- Refined backend API behaviour and data handling for critical paths, focusing on clearer request flow, lower latency, and safer failure handling.
- Integrated authentication and permission flows using JWT and session management, aligning user roles with the data and actions they were allowed to access.
- Maintained CI/CD pipelines and release workflows so changes could be shipped consistently with minimal disruption to active users.
- Investigated production issues, traced failures across services and data layers, and documented fixes so similar incidents were easier to diagnose later.
