What I'm looking for

I'm looking to build scalable, reliable distributed systems where I can own production infrastructure, solve complex backend problems, contribute to emerging AI/ML integrations, and continue mentoring through collaborative Agile engineering.

At Zoho, I've delivered 15+ production enhancements for Java distributed systems supporting thousands of global users. I build scalable backend infrastructure with Java, microservices, Kafka, REST APIs, and event-driven architectures.

I engineered Kafka middleware that scaled multithreaded ingestion to terabyte-level volumes with zero message lag, and built a multi-channel notification framework with 99.9% reliability. I've also improved release operations through Linux shell scripting, reducing manual overhead by 60%.

During my Zoho internship, I fixed a critical Apache Tomcat caching concurrency bug that was merged into the official open-source repository. I also strengthened security by moving hardcoded secrets to an encrypted centralized decryption interface.

I'm active in distributed-systems optimization and AI/ML integration research, and I enjoy mentoring junior engineers through production debugging and technical knowledge-sharing.
