NITHISHA SHANALA

Designed and delivered scalable Java applications (Core Java 17; some modules migrated to Java 21 in 2024) using Spring MVC/Boot, Spring Security, and Spring Cloud for distributed microservices. Implemented security with OAuth/JWT, REST/GraphQL APIs, and Hibernate ORM for high-throughput data processing. Built responsive front-end components with ReactJS and Bootstrap, and developed Node.js/Express microservices to complement backend services. Implemented GraphQL subscriptions and optimized data retrieval; migrated legacy jQuery code to modern frameworks; documented APIs with Swagger; automated tests with Jest. Deployed on AWS ECS/Kubernetes with CI/CD pipelines in Jenkins and GitLab. Introduced Kotlin in select services; implemented Kafka-based real-time data pipelines; containerized with Docker; deployed on OpenShift.

Led digital banking platform modernization by designing and developing secure, scalable API-driven banking applications using Java 17, Spring Boot 3, Node.js, and TypeScript. Implemented RESTful and GraphQL APIs with Kong and AWS API Gateway, securing them with OAuth 2.0 and JWT. Enabled real-time event-driven processing with Apache Kafka and Zookeeper, optimized performance with caching and query tuning, and deployed cloud-native microservices on AWS using Docker, Kubernetes, and OpenShift. Automated CI/CD pipelines integrating extensive testing and enhanced monitoring with Datadog, Splunk, and other tools. Enforced compliance with PCI-DSS and SOX standards and led API modernization efforts.

Directed end-to-end design and development of scalable, API-driven Java applications for healthcare claims and analytics platform using Java 11, Kotlin, Scala, Node.js, and TypeScript. Developed cloud-native microservices and APIs secured with Kong and AWS API Gateway, implementing event-driven architectures with Apache Kafka and Apache Spark for real-time claims processing and predictive analytics. Led migration to microservices with Spring Cloud and automated CI/CD pipelines with Jenkins, GitLab, and Terraform. Enhanced observability with Datadog, Splunk, and Grafana, ensured HIPAA compliance, and developed interactive dashboards with Angular and Vue.js for analytics visualization.
