Modernized legacy GWT/Ant applications by migrating to React (TypeScript) and Spring Boot microservices, improving scalability, maintainability, and performance. Built and integrated responsive React components with Spring Boot REST APIs, including reusable UI elements and business logic layers. Developed services for parsing and transforming SWIFT MX (ISO 20022) and MT messages in high-volume environments, supporting SEPA/RTGS and related payment processing compliance needs. Implemented message processing into Kafka clusters and added monitoring/health endpoints. Led cloud migration from on-prem to AWS, using CloudWatch and Terraform for monitoring and infrastructure automation. Delivered CI/CD pipelines using Harness, and built an AI-powered chatbot to assist with code migration recommendations and productivity for engineering teams. Worked across GitHub Copilot-assisted development, unit testing, Agile delivery, and production support.

Translated complex business requirements into modular, scalable UI using React components and modern JavaScript patterns. Designed and implemented multiple Spring Boot microservices with dedicated REST APIs, ensuring loose coupling between services. Built responsive layouts with HTML5/CSS3 and Bootstrap, and integrated back-end services with front-end through Node.js/Express REST APIs. Implemented ORM with Hibernate/Spring and improved performance through optimized data access. Developed Kafka producer/consumer services for real-time communication and integrated JMS-based asynchronous processing where needed. Orchestrated AWS ECS deployments with auto-scaling and used Azure infrastructure for security and load balancing. Strengthened monitoring using Spring Boot actuator endpoints and integrated CI/CD with Jenkins pipelines. Added authentication/authorization with Spring Security (OAuth2/JWT), migrated legacy capabilities from mainframe systems, and supported production stability with

Built RESTful microservices using Spring Boot and deployed them on AWS and PCF platforms. Developed responsive React UI features with reusable components, hooks, context APIs, and higher-order components. Integrated Splunk for advanced monitoring and observability. Automated deployments using Docker and Jenkins to ensure consistent build/release workflows. Implemented CRUD operations in MongoDB and built Kafka consumers for real-time data processing. Enhanced security using OAuth2 for REST API authentication and created health indicators for integration monitoring. Migrated workloads to Azure and implemented serverless workflows with AWS Lambda and API Gateway, including S3-backed ephemeral storage. Containerized and deployed services via Amazon ECS and AWS CodeDeploy. Built reporting/export capabilities and Spring Batch solutions for batch processing in high-volume environments, while maintaining production reliability through testing, collaboration, and Agile delivery.
