About

I build services that power managed OpenSearch clusters at Oracle — making sure customers get search at scale without ever worrying about what’s under the hood. From scaling Kubernetes deployments to rotating secrets on the fly, I keep clusters healthy, secure, and drama-free (unlike production on a Friday). Previously, I tamed a legacy confirmation system that was allergic to scale — rewiring it into a lean, async, microservices beast. I speak Java and Spring Boot fluently, occasionally whisper to RabbitMQ, and have a soft spot for test coverage above 70%. Off the clock, I swap stack traces for stage scripts. I’ve directed and performed in theatre productions, led marketing campaigns that sold out shows, and can juggle both props and deadlines without dropping either. Whether it’s code or curtains, I love creating things that click.

Senior Software Engineer

Jul 2022 – Present · 3 yrs 11 mos · Bengaluru, Karnataka, India

At OCI, I led key initiatives in building a fully managed OpenSearch service, focusing on automating cluster provisioning, patching, backups, and scaling using Kubernetes, Terraform, Kafka, and Docker. This automation significantly improved customer onboarding and reduced operational overhead.
To strengthen security and isolate customer impact, I redesigned the OpenSearch security plugin with per-cluster secret allocation and built a real-time secret rotation mechanism using Kubernetes Secrets and Java Watchers. This reduced downtime during updates and lowered security risks.
I also introduced robust rollback and retry mechanisms in the patching workflow, reducing update failures by 80%. By integrating Limits API for validations and adding observability through Grafana and OpenTelemetry, I improved stability and cut issue resolution time by 40%.
In addition to development, I contributed to roadmap discussions, mentored junior engineers, and led sessions on TDD and secure coding practices to uplift engineering quality across the team.

At Societe General, I was tasked to modernize a legacy confirmation delivery system that had become a bottleneck for the business — slow, rigid, and unable to scale with growing transaction volumes. Taking ownership of the redesign, I re-architected the system into a modular, microservices-based solution using Spring Boot, REST APIs, and RabbitMQ, enabling seamless scalability and reducing infrastructure costs.
To handle high-volume, time-sensitive confirmations, I introduced asynchronous and multi-threaded processing, achieving a 5× improvement in throughput and helping teams meet stricter SLAs. I built a distributed messaging layer to ensure high availability and consistent delivery under peak loads.
Focusing on long-term quality, I enforced a TDD approach with JUnit and Mockito, maintaining over 70% test coverage. These improvements directly led to a 40% boost in delivery accuracy, significantly improving client trust and earning me top performer recognition within the Sirocco Business Unit.
