• Led end-to-end migration from monolithic architecture to Spring Boot microservices handling 10M+ daily transactions across 3 global regions (NA, EMEA, APAC) using circuit breaker and event-driven design patterns. • Engineered and maintained RESTful APIs with optimized SQL queries and Redis caching strategies, boosting response efficiency by 30% and reducing p99 latency by ~40ms. • Managed enterprise-grade microservices on GCP (GKE) via Kubernetes and Helm, streamlining deployment efficiency by 40% and maintaining a 99.9% uptime SLA. • Analyzed and refined complex SaaS billing algorithms for the Clover product line, achieving a 15% increase in processing speed and 10% reduction in infrastructure costs. • Orchestrated robust CI/CD pipelines using Jenkins and Docker, cutting manual deployment latency by 75% and enabling zero-downtime releases. • Implemented automated monitoring and Grafana dashboards, reducing critical system downtime by 25% via proactive root cause analysis. • Scaled quota backend services to handle a 2x increase in event volume without additional infrastructure provisioning. • Mentored 2–3 junior engineers through rigorous code reviews and architecture design sessions; authored comprehensive technical specifications (architecture & sequence diagrams) reducing technical debt by 10%.

Earlier System- Requesters used to send email which didn’t had any consistent format, The request was recorded in an excel file by the admin. Admin used to manually find and enter the data from mails to system and had to save the attachments at an appropriate place. Admin had to manually send mail to each and every person. New System- A request form was designed for requesters so there is consistency maintained when request is sent. Data was stored in Microsoft SQL Server, which made data secured as well as integrated. Semi- automated and automated generation of mails eased the work of admin. Only authenticated and authorized person is able to access the system. The process of fulfilling the request becomes faster.
