Engineering Reliable Refund Workflows for an Airline Platform
An enterprise backend case study focused on reliable refund workflow state transitions.
An enterprise backend case study focused on reliable refund workflow state transitions.
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.
