Ayush Soni

I’m a Senior Software Development Engineer with 8 years of backend and microservice experience, focused on building scalable, cloud-native systems with Java and Spring Boot. I bring deep expertise in microservices, event-driven architectures, REST APIs, and strong security foundations using OAuth 2.0 / OIDC.

At EPAM Systems, I designed and implemented a high-throughput, event-driven file processing system using Spring Integration and Java Watcher API, enabling real-time handling of thousands of files per minute. By optimizing legacy synchronous workflows with parallel processing and multithreading, I achieved a 100x improvement in processing speed and system responsiveness, while leading design discussions around scalability, security, observability, and performance.

Previously at Cognizant, I built RESTful APIs and microservices with Java Spring Boot and implemented OAuth 2.0 / OIDC-based authentication and authorization across enterprise applications. I integrated Kafka, ActiveMQ, and databases, worked across hybrid cloud and on-prem setups, and used Kubernetes for deployment, scaling, and operations of containerized microservices.

I also contributed to microservices migration and RESTful API design, and early on improved test efficiency by developing automated test scripts with Robot Framework. I’m especially proud of modernization and migration work (including cloud readiness for secure deployment, Java 8 to Java 21 upgrades, and AWS/Azure-aligned governance), and I value clean architecture, automated testing, and continuous improvement in delivery.
