Led end-to-end SDLC in Agile, partnering with Product, QA, and DevOps to deliver scalable and secure enterprise applications. Built modern microservices with Java 21 and Spring Boot REST APIs, implementing OAuth2/JWT security controls. Developed cloud-native solutions on AWS (EC2, S3, IAM, VPC, EKS) and integrated AI capabilities using AWS Bedrock for secure, AI-powered experiences. Containerized services with Docker and deployed on Kubernetes with health checks, rolling updates, and autoscaling. Implemented CI/CD using GitHub Actions and Jenkins, applied SonarQube quality gates, and monitored production using AWS CloudWatch and centralized logging. Engineered event-driven and batch workflows using Apache Pulsar/NodeJS and Spring Batch for reconciliation, reporting, and large-scale processing. Performed production issue diagnosis, performance tuning, mentoring, and code reviews while maintaining engineering documentation.

Led end-to-end Agile SDLC, collaborating with product, QA, and DevOps teams to deliver secure, high-quality enterprise services. Designed and modernized Java 21 microservices using Spring Boot and REST APIs, implementing OAuth2/JWT security and role-based access. Built cloud-native solutions on AWS with EC2, S3, IAM, VPC, EKS, and integrated AWS Bedrock for AI-powered capabilities. Developed responsive front-end components with Angular 18 and TypeScript, connected to backend REST services, and implemented scalable persistence using Spring Data JPA/Hibernate with PostgreSQL and MongoDB. Implemented event-driven and asynchronous processing using Apache Pulsar and NodeJS, plus large-scale batch workflows via Spring Batch. Containerized and orchestrated services with Docker and Kubernetes; automated CI/CD using GitHub Actions/Jenkins with Maven, integrated SonarQube quality gates, and monitored via AWS CloudWatch and logging.

Managed full-cycle delivery for enterprise financial systems using Agile collaboration with development, QA, product, and compliance teams. Architected backend microservices with Java 19 and Spring Boot for high-volume transaction processing and banking integrations. Implemented enterprise-grade security using Spring Security, OAuth2, and JWT with fine-grained authorization and audit controls. Built Spring Batch workflows for settlements, reconciliation, and regulatory reporting; optimized persistence and query performance using Spring JPA/Hibernate with PostgreSQL and MongoDB. Developed responsive dashboards and portals using Angular 17 with NgRx, TypeScript, and Bootstrap. Modernized legacy systems via microservices transformation and event-driven communication using Apache Pulsar. Delivered AWS cloud-native infrastructure using Terraform, EC2, S3, IAM, and VPC; deployed on Kubernetes (EKS) with auto-scaling and health monitoring. Automated CI/CD with GitHub Actions, AWS CodeDeploy,
