I'm a results-driven IT professional with a rare intersection of cloud engineering, cybersecurity, and full-stack development expertise.

At IRCTC, I secure Java-based mission-critical booking systems serving millions of daily users — handling API security testing, log analysis for threat detection, and SQL-based financial validation. Previously at Cognizant, I architected AWS-native serverless applications using IAM, KMS, and VPC hardening, while building CI/CD pipelines and managing container orchestration.

My B.Tech in Computer Science (Cloud & Mobile Apps) from SRM University, combined with ongoing IIT Guwahati cybersecurity training, gives me a strong theoretical foundation to match my hands-on experience. I'm passionate about making software that is both fast and secure.
