What I built
- Architected a multi-tenant platform of 11 Django apps with per-tenant data isolation and multiple branches per business.
- Implemented UAE VAT tax invoices with TRN, locked issued invoices corrected through credit notes, and custom payment terms with due-date calculation.
- Designed role-based access control with 29 granular permissions and 8 customisable default roles, enforced centrally on every API request.
- Ran 127 schema and data migrations on the live PostgreSQL database.
- Wrote 527 automated backend tests with a GitHub Actions CI pipeline.
- Built a deployment script that backs up the database, uploads Docker images and restarts the services without manual server steps.
