Internal Certificate System

Built an internal certificate-issuance platform for a global music industry association, used by stakeholders worldwide. Replaced a fragile, mostly-manual process with a structured system covering issuance, review, and audit history.

Multiple stakeholder roles, regulatory traceability requirements, and a long-running manual workflow that was hard to audit and slow to evolve.

1. Designed a Django REST Framework API with clear domain boundaries between certificates, applicants, and reviewers.
2. Implemented role-based access and review workflows so each stakeholder only sees the steps they own.
3. Delivered a React admin front-end with focused screens per workflow stage rather than generic CRUD.
4. Hosted on AWS with a deployment pipeline that supports controlled iteration on a sensitive system.

Python and DRF and React and MySQL form the core stack, with the application hosted on AWS and delivered through a controlled pipeline.

• Replaced manual certificate handling with a traceable, audit-friendly workflow.
• Reduced operational overhead for the issuing team.
• Built a foundation that can absorb future regulatory and process changes without a rewrite.

The most valuable architecture was not the most elaborate one. It was the set of boundaries that let the team make local changes while preserving confidence in the whole system.
