About Project

Emirates Group's important digital transformation project is called Omni Channel Service Layer (OCSL) where I was a key member of the platform team. In which, we were responsible for developing first of its kind cloud platform with capabilities to support the polyglot micro-services, a well-designed API Gateway (using Spring Cloud Gateway), incorporated cutting edge real-time monitoring and log visualization capabilities (using Splunk & AppDynamics ). It helped to implement Agile & DevOps way of a working model, and aided organization's digital transformation greatly.

Roles & Responsibility

• Involved in technical design for micro-services and API design.
• Involving in NoSQL data modelling
• Helping peer developers in technical challenges
• Did POCs to enrich Micro-service platform (OCSL)
• Integrated Splunk tool (for Application monitoring and log visualization)
• Co-ordinate with QA, DevOps & Solutions Architect members
• Performance engineering to improve the overall performance of the micro-services
• Involved in interviewing candidates for backend engineering
