Led the design and rollout of a compliance validation tool to verify pricing accuracy for offers and subscriptions; this cut rollout timelines from months to days and reduced member billing errors.

Collaborated with product, data science, and marketing teams to design and execute A/B tests and experiments, ensuring API and UI changes aligned with business goals and improved user engagement.

Spearheaded e-commerce platform enhancements, integrating APIs for payment, fulfillment, and delivery tracking while enabling marketplace expansion—supporting a 3x increase in order volume.

Automated observability workflows using Terraform and New Relic, resulting in 30% faster incident detection and 25% fewer false positives through improved dashboarding, monitoring, and alerting.

Led distributed tracing and observability POCs with OpenTelemetry, FluentD, and New Relic; evangelized adoption across teams via internal tech talks and live demos on anomaly detection and service maps.

Championed modernization of the backend stack, migrating legacy services to Node.js/TypeScript, and upgrading critical infrastructure components like Kubernetes, JDK and Spring Boot for improved maintainability and security.

Maintained and enhanced the core commerce backend platform by resolving performance bottlenecks, implementing critical business logic, and reducing technical debt.

Led infrastructure-as-code deployments using Terraform for critical microservices on AWS EKS, ensuring repeatable and secure service rollouts.

Spearheaded design and development of unique LI solution for 5G, LTE, VoIP/VoLTE environment on the cloud, on-premise, or hybrid deployment. Created design solutions incorporating standard telecom use cases like Mobile Number Portability (MNP), Session Border Controllers (SBC), and Telephony Application Servers (TAS). Championed the use of weekly meetings with clients and stakeholders on the project and product updates and risks. Partnered with the pre-sales team for conducting product introductions and demos. Engaged with client's business and technical teams on phase-vise solutions for both user and technology adoption and roll-out plans and milestones. Communicated and actively worked with OEM partners on the client's behalf to understand and mitigate any technical gaps to ensure smooth product roll-outs. Mentored and nurtured people to grow in roles like scrum master, technical architects, team leads, dev-ops, and dev-ops lead. Instituted a cadence of monthly release cycle ensuring timely feedback maintaining client's engagement and team's focus.

Headed development of LTE based polyglot LI solution interfacing with various LTE components including SGW, PGW, MME, HSS, DRA. I practiced both my technical and managerial skills in this project. On one hand, I was involved with customers for requirements and creating project milestones and plans. On the other hand, I had designed/implemented GTP tunnel management required for control plane and user plane establishment, Redis replication strategy across multiple nodes for faster lookups, mediation components for HI2 and HI3 LEA delivery, implemented target propagation system, DRA for updating in-flight AVPs between MME and HSS via DRA. Worked with the QA team to ensure all test scenarios are automated using LTE simulator and test results are captured and available on Jenkins. Organized and practiced continuous integration to ensure stable tagging and releases for regular and hotfixes builds to customers. Performed various POC around Mesos, Marathon, Chronos, Prometheus, Docker, Docker Swarm and Docker compose.

Primary engagement around product development, deployment and support for business-critical applications. Spearheaded "Canary" based deployments to minimize production downtime and smoother rollbacks if required. Developed Splunk/AspectJ based monitoring solution for overall production health checks. Designed Oracle TimesTen replication strategy to data availability on edge nodes. Developed application on Blackberry mobile platform and web services for Weblogic middleware applications. Championed use of maven release artifacts for regular and production deployments and hotfixes. Responsible for requirement management and prioritization. Worked on Oracle Fusion Middleware - SOA and ESB.
