What I'm looking for

I’m looking to join an established firm that offers excellent career growth, with challenging tasks that help me hone my programming skills further, while applying my experience in advanced technology and Agile execution to deliver on-time results.

I’m a results-oriented professional with 5+ years of experience, focused on advanced technology and capacity planning. I’m currently working as a Senior Developer at Cognizant, where I develop and maintain RESTful APIs using Spring Boot and Java 8, and design microservices architectures to improve scalability and maintainability.

In my work, I strengthen security and reliability by implementing JWT authentication and Spring Security for secure API access, and by optimizing MySQL queries to improve application performance and reduce response times. I’ve also delivered SAP Hybris ecommerce solutions (WCMS customization, new-site setup, custom populators, and Flexible Search services), write and verify JUnit/Mockito tests with code-quality focus, and collaborate across teams using Agile/Scrum practices.
