Developed full-stack digital wallet provisioning solutions using Java (Spring Boot) on the backend and ReactJS on the frontend. Implemented RESTful APIs for multi-step provisioning, including card validation, challenge-based authentication, unlink/relink logic, and secure mapping to short-lived provision keys. Integrated Kafka for async provisioning status events and user action logs. Built scalable session management with DynamoDB TTL and cache invalidation. Designed secure data pipelines for eligibility and risk orchestration with MFA, header-based authentication, and multi-channel redirects. Implemented RabbitMQ clusters for reliable messaging in cloud and on-prem. Containerized microservices with Docker, orchestrated on AWS ECS/EKS, with API Gateway, Lambda, S3 and CloudWatch. Introduced defensive patterns against ID enumeration, insecure redirects, and session replay. Wrote unit tests (JUnit/Mockito); used Git and Jenkins for CI/CD.

Developed full-stack digital wallet provisioning solutions using Java (Spring Boot) on the backend and ReactJS on the frontend, enabling secure card eligibility checks, risk assessments, and session-driven user flows across mobile and web platforms. Engineered RESTful APIs to handle multi-step provisioning operations, including card validation, challenge-based authentication, unlink/relink logic, and secure mapping of backend records to short-lived UI-safe provision keys. Integrated Kafka to publish provisioning status events, session expiration alerts, and user action logs for real-time analytics and fraud monitoring. Built scalable session management backed by DynamoDB with TTL enforcement, and designed secure data pipelines to support eligibility and risk orchestration. Implemented RabbitMQ clusters for reliable messaging across on-prem and AWS environments. Managed microservices with Docker, orchestrated on AWS ECS, and used AWS Lambda for lightweight post-provision operations. Con

Java Full Stack Developer at UBS

Designed and developed microservices for a financial client onboarding platform using Spring Boot and AWS to ensure scalability and security. Applied CQRS to separate read/write operations for high-traffic scenarios. Integrated AWS services such as S3 (document storage), DynamoDB (high-velocity data), and RDS (structured data), and managed secrets with AWS Secrets Manager and IAM-based access control. Automated onboarding workflows using AWS Lambda for real-time validation, fraud detection, and notifications; used SNS/SQS for decoupled asynchronous communication. Implemented API Gateway for secure RESTful APIs and ELB for high availability. Monitored performance with CloudWatch and built responsive React-based UIs for onboarding workflows. Collaborated on CI/CD pipelines with Jenkins, Docker, and ECS.
