Overview

I worked on Caribbean Airlines refund management workflows using Python, Django REST Framework, PostgreSQL, and REST APIs.

Problem

Refund systems require reliable state transitions, backend validation, secure access, and auditability. Workflow changes must be regression-safe because a mistake can affect operational and customer-facing processes.

Engineering Focus

The backend work emphasized refund workflow validation, secure API access, role-aware authorization where appropriate, audit trails, and reliable state transitions.

Outcome

The project strengthened enterprise backend workflow handling while avoiding unsupported claims about refund values, payment providers, transaction volumes, infrastructure, or SLA numbers.
