✦Supplier management platform for a copper miner, built from the ground up

Software Architect

Architected and built from scratch the supplier management platform of a Chilean copper mining company, bringing contract letters, new-supplier onboarding and supplier risk into a single system.
Set up a monorepo with one Next.js app per module and shared TypeScript packages (UI kit, typed API client, auth) on top of a FastAPI and PostgreSQL backend.
Integrated Entra ID with role-based permissions, DocuSign e-signature through signed webhooks, Microsoft Graph, Azure OpenAI, and master-data ingestion from the client's source systems.
Built the Azure DevOps pipeline — lint, type checks, tests, Playwright and Trivy scans — with per-environment builds and production releases through a staging-slot swap on Azure App Service behind Front Door.
Keep an audit wiki in sync with the code on every PR, covering access control, traceability and data handling.
