Designed and developed scalable microservices using Spring Boot, Spring MVC, Spring Data JPA, and Spring Security, exposing RESTful APIs with standardized contracts. Built and tuned AWS infrastructure with RDS (reader/writer), integrating PostgreSQL, Oracle, and Cassandra; implemented cloud-native deployments on EC2, ECS (Fargate), S3, SQS, EMR, Lambda, API Gateway, and VPC. Implemented containerized deployments with Docker and Kubernetes (EKS) and automated releases via Jenkins CI/CD pipelines. Developed serverless Python-based APIs on AWS Lambda using event-driven patterns. Built asynchronous processing workflows using JMS and AWS SQS, and implemented batch/data processing with Spring Batch and AWS EMR transient clusters. Integrated AI-powered capabilities using OpenAI APIs to support automation and intelligent decision-making features. Secured applications with OAuth2/JWT and Spring Security, performed vulnerability remediation from security scan results (e.g., Fortify), and maintai

Modernized legacy monolithic services into scalable microservices using Spring Boot and related tooling, including REST APIs and SOAP services. Implemented event-driven architectures with Apache Kafka and deployed workloads on AWS ECS (Fargate) and EC2. Built and enhanced self-service UI modules and integrated them with backend services. Configured AWS services such as RDS, Lambda, SQS, S3, Route53, load balancers, and security groups, improving performance and data consistency with PostgreSQL/MySQL. Developed data access layers using Spring Data JPA, Hibernate ORM, and DAO patterns; optimized batch processing using AWS EMR transient clusters. Streamlined CI/CD pipelines using Jenkins and Maven to reduce release time, containerized applications with Docker, and improved security by remediating vulnerabilities identified through tools like Twistlock/WhiteSource/Checkmarx and Docker scans. Implemented monitoring and logging with Splunk, Datadog, and CloudWatch Logs; conducted load/stress

Developed enterprise applications using Spring Boot microservices to support scalable and distributed data platforms on AWS. Built responsive UI components using HTML5/CSS3/JavaScript/jQuery/JSON and integrated them with backend REST APIs. Implemented persistence layers using Hibernate ORM including sessions, transactions, and HQL/Criteria queries. Managed AWS infrastructure including EC2, S3, VPC, security groups, and ELB; automated provisioning with Python scripts. Used Puppet/Chef/Ansible for configuration and deployment in Linux environments. Designed relational schemas in PostgreSQL and applied common J2EE design patterns such as DAO/DTO and service-layer patterns. Created private Docker registry and supported containerized deployments on AWS and Kubernetes. Implemented event-driven processing by consuming messages from queue-based systems, standardized API documentation with Swagger/OpenAPI, and managed data retention using S3 versioning and lifecycle policies.
