Core Skills
Java (strong proficiency)
Git for version control
Unit Testing (Junit for Apache Camel)
For Apigee

• Experience with API proxy creation (e.g., Reverse Proxy, Target Endpoint, Route Rules)
• Policies: security (OAuth2, API Key), mediation (XML/JSON transformation), traffic management (Spike Arrest, Quota)
• Debugging and tracing tools in Apigee
• API versioning and lifecycle management

API Design & Standards

• RESTful API design principles
• OpenAPI/Swagger specifications
• Familiarity with GraphQL (optional but useful)

Security

• OAuth 2.0, JWT, API Key validation
• TLS/SSL, CORS, and threat protection policies

For Apache Camel

• Route creation using Java DSL or XML DSL
• Working with Camel components (HTTP, JMS, File, Kafka, etc.)

Spring Boot

• Building microservices with Spring Boot + Camel
• Dependency injection and configuration management

Data Transformation

• JAXB, Jackson for XML/JSON transformation

Error Handling & Logging

• Camel error handling strategies (onException, doTry/doCatch)
• Logging and monitoring with ELK
