The project involved the design and development of a Spring Boot-based microservices platform called General Summary Integration, which enables healthcare clients to generate patient summary PDFs devoid of sensitive data. These summaries are retrieved from mainframe systems (GCS7100C CICS), processed by a PDF composition service (Scalar), and delivered via a web interface built by the Web COE team. The system ensures auditability and traceability through detailed logging into SQL Server, with integration to Cognos for business reporting and analytics

Sr J2EE Developer

AT&T

The project involved modernizing AT&T’s Identity and Access Management (IAM) infrastructure under the Chief Security Office (CSO). The goal was to design and deliver a robust, scalable, and secure authentication and authorization framework for internal and external AT&T applications, including Consumer IAM, Enterprise IAM, and FirstNet IAM. The solution enforced centralized security using industry-standard protocols like OAuth2, OIDC, and SAML, integrated with platforms like Okta and AWS Cognito, and transitioned legacy monolithic systems to cloud-native microservices architecture using Spring Boot and AWS. The IAM framework supported user session management, Single Sign-On (SSO), and token- based authentication, acting as a policy enforcement layer via IAM PEP (Policy Enforcement Point) servers, which intercepted and routed secure resource access requests to backend services.

Built POCs and production-ready solutions for event-driven architecture, modeling internal business events and data models to support real-time IAM activities.

Automated builds and deployments using both Maven and Gradle, publishing artifacts to internal Docker registries.

Implemented observability and logging using AWS CloudWatch, CloudTrail, and Swagger/OpenAPI documentation. Leveraged Amazon S3 for secure document and token storage, and Lambda for event-driven compute tasks.

Ensured high availability and failover by configuring AWS Route53, Auto Scaling, EBS, and CloudFormation.

Performed rigorous testing and validation of security flows using Mockito, Postman, and Selenium to simulate real-world IAM scenarios.

Collaborated with DevOps, IAM Operations, and Security teams to monitor, troubleshoot, and resolve IAM-related issues in production.

Participated in Agile ceremonies (daily stand-ups, sprint reviews, retrospectives), working closely with product owners and architects to align deliverables with business requirements.

Maintained compliance with industry security standards (such as NIST, SOC2, etc.) by following secure coding, encryption, and identity lifecycle best practices.
