Cosmos (AWS and GCP):• Contributed to control-plane microservices responsible for managing the lifecycle of Thoughtspot tenant clusters. • Reduced cloud costs by contributing to in-house cloud cost management solutions like dynamic resizing of EC2 instances to downscale underutilized resources, automatic cleanup of orphaned resources, enforcing lifecycle rules on s3 buckets. • Developed Zero-downtime upgrade process, eliminating the 4+ hours of downtime during monthly upgrades.• Leveraged Kubernetes controllers to continuously monitor and enforce the desired infrastructure state.• Leveraged terraform and ansible to setup control-plane and tenant cluster infrastructure.• Developed a lightweight serverless bootstrap job to deploy and manage the CD agent for K8s clusters.• Led migration of sensitive public endpoints to a secure private zone, strengthening security protocols and restricting access to trusted connections. This initiative safeguarded privately hosted services, significantly enhancing overall security.• Implemented IP-based access control system, restricting cluster access to designated IPs. Enforced security protocols to prevent unauthorized entry, issuing a 403 Forbidden error for any unauthorized attempts.• Led the upgrade of Vault to its latest version, fortifying the reliability and security of our secrets management system. Introduced a custom Grafana dashboard for real-time monitoring, enhancing visibility into key Vault metrics and performance.

Developed a Thread Dump Analyzer to extract out useful hints to diagnose performance issues of Java applications. Generated analysis report for single thread dump file as well as a zip of multiple thread dump files. Implemented algorithms to identify Deadlock, classifying threads based on their properties.Implemented bottom-up call stack tree using stack traces of threads• Exposure: Java, HTML, CSS, JavaScript, Rest API, JSON, Git.
