Experience

  • Infrastructure Health Monitoring for Morgan Stanley

    A modern UI Web Application on top of legacy Data Sources with multiple integration points. As Solution Architect, I produced High-Level Solution Architecture.

In addition, I performed an application code review.

  • Business Intelligence Solution with Modern UI/UX for Pratt & Whitney Canada

    An enterprise business intelligence solution with modern UI/UX.
