Maintain GitHub Actions CI/CD for the portals, API, background workers, and shared packages; automate formatting, analysis, type checks, tests, contract checks, security checks, and builds.
Prepare releases traceable to a commit and environment; deploy to development, test, and production, verify service health after each release, and roll back when checks fail.
Design and maintain REST endpoints with Node.js and NestJS; define requests, responses, validation, and errors, and keep OpenAPI aligned with the implementation.
Model data in PostgreSQL, enforce authorization and organization-level isolation, and prepare safe queries, transactions, and schema changes.
