Engineered scalable microservice architecture in Java/Go, driving key architectural decisions that improved reliability, scalability, and enabled handling of 100M+ daily messages with 99.99% uptime. Builtevent-driven messagingsystems(pub/sub, retries, DLQs) andmulti-tenant Kafkaconsumers, boosting delivery success by30%and achieving10KTPSthroughput. Diagnosed and resolved random latencyspikesin the API gateway during peak traffic by identifying long GC pauses and low heap memoryin Java pods, stabilizing performance and eliminating unpredictable slowdowns. Developed Kubernetes-integratedAPIsfor on-demand pod creation by data segments, cutting deployment time from5minto30sec(90%faster). Led production deployment onAWS&KubernetesusingHelm, dynamic logging, and observability tools (Coralogix/Splunk), ensuring fault-tolerant and scalable infrastructure. Designed efficient databaseschemasand managed MySQL, enabling high-throughput data access and optimized storage. Automated CI/CDpipelinesandTDD-basedtesting, accelerating release cycles by400%and ensuring full coverage of critical event flows. Created internal developertooling(Postman collections, documentation) and monitoring frameworks, fast-tracking developer onboarding by 4x

Developed a secure web platform with authentication and encryption for experts to efficiently resolve student queries. Integrated backend APIs to handle real-time query submissions and responses, ensuring fast and reliable communication between experts and students. Built using the MERN stack (MongoDB, Express, React, Node.js), implementing full-stack functionality and responsive UI.
