Highlights

  • Migrated auth from Clerk to Supabase across three Next.js apps (Admin, Wiki, Influencer) and an Express/NestJS API, with RBAC and Row Level Security on all 47 Postgres tables. 132 commits, 20,000+ insertions across 400+ files.
  • Designed CI that runs only affected tests, cutting single-module pipelines from 20 to 8 minutes in GitHub Actions.
  • Consolidated validation onto Zod contract schemas, retiring 20+ legacy validators (4,700+ lines removed); shipped releases on Railway.
  • Secured the API surface: Supabase JWT middleware, device-based RLS, ownership guards, and a custom access-token hook emitting user roles into every JWT, reviewed, tested, and documented across 170+ endpoints in OpenAPI.
