Built venVUE, an enterprise parking management platform processing millions of transactions annually, and integrated AWS S3/CloudFront for centralized configuration and CDN distribution. Collaborated with Product/QA in an Agile (SCRUM/Kanban) environment, performed structured code reviews, and deployed on IIS/Windows Server with optimized session handling.
