Project :- US Retail Client

Backend API Development:

• Designed, developed, and maintained robust backend APIs using Reactive Spring Boot.
• Implemented asynchronous, non-blocking API services to enhance performance and scalability.
• Utilized Reactive Programming principles to handle high-throughput and low-latency requirements. Ensured seamless integration of APIs with various microservices and third-party systems.

Logging and Monitoring:

• Modified logging filter logic to provide different approach, replacing use of MDC Context Lifter.
• Developed and implemented custom logging solutions to improve traceability and debugging capabilities.

Testing and Quality Assurance:

• Developed comprehensive JUnit test cases to ensure code quality and functionality.
• Implemented integration tests to validate end-to-end API workflows and interactions.
• Utilized Mockito and other testing frameworks to create mock objects and simulate external dependencies.
• Conducted code reviews and collaborated with QA teams to identify and fix bugs.

Database Management:

Worked extensively with Azure Cosmos DB to manage and query data.

Continuous Improvement and Optimization:

• Participated in Agile ceremonies including daily stand-ups, sprint planning, and retrospectives.
• Collaborated with cross-functional teams to gather requirements and deliver high-quality solutions.
• Monitored application performance and optimized code for better efficiency and lower latency.

Documentation and Support:

• Created and maintained detailed API documentation for internal and external use.
• Provided support and troubleshooting for API-related issues reported by clients or internal teams.
• Offered technical guidance and mentoring to junior developers.
