What I'm looking for

I'm looking to build scalable, reliable backend systems where I can work on Java and Spring Boot APIs, distributed systems, performance optimization, security, and production-grade engineering.

At Cognam Technologies, I built and integrated Java and Spring Boot backend systems for enterprise applications, improving API pagination and sorting efficiency by 45%.

I designed backup, restore, and real-time configuration recovery capabilities for the Facility Application, reducing backup and restore time by 60% while improving reliability and reducing downtime. I also strengthened authentication flows with MFA lockouts and security notifications, reducing unauthorized access attempts by 75%.

I work across RESTful APIs, Kafka, MySQL, microservices, testing, and production issue resolution. My Banking System project applies these skills through a Java and Spring Boot microservices backend for customer and financial operations, with WebSocket-based real-time communication.

I'm focused on scalable, production-grade engineering, from transactional data operations and system design to secure user experiences and reliable delivery pipelines.
