I build scalable Java backend services for banking, payments, and data automation.
IndiaWhat I'm looking for
I'm building secure, scalable backend microservices for banking and payment workflows at AppRely Technologies. I created a unified transaction API that lets merchants integrate with multiple banks through a standardized payload, alongside approval workflows and Kafka-driven transaction notifications.
Previously at Capgemini, I engineered a Spring Boot service integrating Azure DevOps REST APIs, improving data retrieval speed by 10% and reducing reporting delays by 30% through real-time Power BI dashboards.
I work across Java, Spring Boot, REST APIs, Kafka, Docker, AWS, PostgreSQL, and MySQL. I've improved backend performance by approximately 20% through SQL optimization and eliminating redundant database calls.
Outside work, I built a retrieval-augmented code-search tool over my DSA notes and a Spring Boot blog platform with JWT authentication, role-based access control, and content management features. I've also solved 300+ DSA problems on GeeksforGeeks and 150+ on LeetCode.
