I build and ship full-stack systems across the entire stack - MERN, Spring Boot, AWS and Mainframe - end-to-end, every layer. Currently at TD Bank, building enterprise Node.js and Spring Boot APIs that bridge modern distributed services to enterprise mainframe backend. I also build AI tooling on top - autonomous agents, prompt libraries - usually before it's on anyone's roadmap.
End-to-end MERN applications from database to UI. MongoDB for data, Express and Node for APIs, React and Next.js for interfaces. JWT auth, server-side rendering, real-time updates, and test suites that run before every deploy.
Production workloads on AWS and Azure. Dockerized services orchestrated with Kubernetes, event-driven pipelines through Kafka, and infrastructure defined in code. CI/CD through GitHub Actions and AWS CodePipeline with CloudWatch and Datadog for observability.
Native Android and iOS applications shipped to both stores. SwiftUI for Apple platforms including WatchOS companions, Kotlin and Material 3 for Android. Push notifications, offline-first sync, and CI/CD through Fastlane for automated store submissions.

Standalone COBOL programs, JCL job streams, and batch scheduling through CA-7. Day-to-day work in TSO/ISPF, source control via Endevor, and debugging with IDz. DB2 for relational data, IMS DB for hierarchical. Enterprise batch that processes millions of records overnight.
The bridge between mainframe and modern. z/OS Connect maps CICS COMMAREA and DB2 result sets to clean REST/JSON endpoints that any React app, mobile client, or microservice can consume. OAuth, JWT, and Zowe CLI for automation. Legacy data, modern interface.
