Closing enterprise B2B SaaS, fintech, or government contracts requires bulletproof identity and access management: OAuth 2.0, OpenID Connect (OIDC), SAML 2.0 Single Sign-On (SSO), Role-Based Access Control (RBAC), machine-to-machine (M2M) client credentials, and custom token-exchange gateways.

If you need to hire a freelance OAuth 2.0, OIDC, SSO, and multi-tenant identity programmer across Go, Python, and TypeScript, I am Aldian Fazrihady.

Identity & Authentication Architectures I Deliver

1. Custom Token-Exchange Gateways & Identity Bridges in Go

I build high-throughput Go identity gateways (Architecting a Token-Exchange Gateway in Go and Designing Identity Bridges) including national digital identity integrations like Singapore's Singpass & MyInfo (Bridging Enterprise Auth with Singpass & MyInfo).

2. Multi-Tenant HIPAA SMART-on-FHIR & Auth0/Cognito Automation

From automated M2M Auth0 client provisioning (Securing M2M Communications with Auth0) to HIPAA-compliant AWS Cognito SMART-on-FHIR identity (Multi-Tenant HIPAA Identity), I secure complex multi-resource ecosystems.
