• As a Senior Java Full Stack Developer, I contributed to building scalable enterprise applications by developing microservices using Java 11/14, Spring Boot, Spring MVC, and Spring Batch, while delivering responsive front-end solutions with Angular 7, TypeScript, and Bootstrap. I deployed Dockerized services on AWS (EC2 and Fargate), leveraging Terraform for infrastructure provisioning and Kubernetes for container orchestration, and streamlined CI/CD pipelines with Bamboo to improve release efficiency and reliability. Worked closely on payments transformation initiatives, aligning backend services with enterprise payment rails and downstream systems associated with SWIFT, FED, and CHIPS settlement and messaging flows.
• Supported modernization initiatives leveraging the Finxact Core Banking Platform, implementing deposit product configurations, transaction posting rules, and GL alignment workflows. I supported secure cloud deployments by implementing AWS IAM roles and policies for service-level access control and resource isolation. My work included optimizing data access using Spring Data JPA and Cassandra, enabling asynchronous messaging with RabbitMQ, and enhancing observability through Nagios and Grafana for monitoring, alerting, and performance tracking. Deployed and managed backend services on OpenShift (OCP), leveraging container orchestration, rolling deployments, and platform-level resiliency.
• I improved system quality through automated testing with TestNG, Karma, and JaCoCo, along with structured logging using Logback, and collaborated closely within Agile teams to ensure iterative delivery, maintainability, and high-quality outcomes.

• Senior Java Backend Engineer with strong experience supporting enterprise healthcare and pharmaceutical systems in highly regulated environments requiring strict data integrity, traceability, and compliance with clinical standards. Extensive hands-on expertise building backend services using Core Java and the Spring Framework, delivering reliable and auditable integrations across laboratory and clinical platforms.
• Specialized in designing and implementing instrument interface components to automate data exchange between laboratory and diagnostic instruments and backend enterprise systems. Experienced in device-to-system communication using TCP/IP socket programming, file-based integrations, and real-time data ingestion pipelines to capture raw instrument output at scale.
• Proven ability to parse, validate, and transform instrument-generated data into structured backend formats, ensuring accuracy, completeness, and consistency before persistence and downstream processing. Hands-on experience integrating clinical workflows using HL7 v2.x messaging (including ORU and ORM message types) and ASTM E1381/E1394 standards to enable interoperability across laboratory information systems and enterprise healthcare applications.
• Collaborated closely with laboratory SMEs and instrument vendors to understand end-to-end lab workflows, including test ordering, quality control, result validation, and exception handling. Regularly reviewed vendor specifications, communication protocols, and data formats, translating technical documentation into robust and maintainable backend integration logic.
• Acted as an SME for instrument interface modules, owning enhancements, defect resolution, regression testing, and impact analysis of interface changes. Performed onsite system analysis and integration testing, validating end-to-end data flow from physical instruments through backend services.
