I build and stabilize production B2B SaaS: multi-tenant boundaries, RBAC/SSO, billing state machines, and OAuth integrations — shipped safely with staged rollouts, migrations, and observability.
Focus areas
- Multi-tenancy & data isolation (workspace/org scoping across API/DB/storage)
- Auth, RBAC & enterprise SSO (SAML/OIDC)
- Billing + entitlements (trial → active → past_due → suspended), webhooks
- Integrations (OAuth, token security, idempotency, retries)
- Migrations/refactors without downtime + release safety
- Observability (logs/metrics/traces), alerts, runbooks
