Project details

I design and build scalable, secure, serverless REST APIs on Microsoft Azure using cloud-native architecture and Infrastructure as Code (IaC).

My solutions leverage Azure API Management (APIM) and Azure Functions to deliver highly scalable, cost-effective APIs. APIs are designed from OpenAPI specifications, which I can also create from scratch.

Services include:
• OpenAPI/Swagger design and documentation
• REST endpoint modeling and validation
• Authentication and authorization design
• API versioning and governance
• Azure API Management and Azure Functions integration
• Monitoring, logging, and observability

Supported authentication:
• APIM Subscription Keys
• Microsoft Entra ID (Azure AD)
• OAuth 2.0 / OpenID Connect
• JWT validation policies

Supported runtimes:
• Node.js (JavaScript/TypeScript)
• Python

Infrastructure as Code:
• Terraform
• Pulumi

Serverless architecture provides automatic scaling, high availability, lower operational overhead, and pay-per-use pricing. I focus on clean architecture, maintainable code, security best practices, and production-ready Azure solutions that scale with your business.
