About

With a career that began as a Software Developer, I have progressively advanced to roles requiring expertise across almost every aspect of IT operations and development. My journey has taken me from Applications Developer to Vice President of Software Engineering at Citicorp Global Technology Infrastructure. Currently, I am a hands-on Technical Delivery Manager, overseeing software development and application operations for over 80 enterprise applications. This experience has given me a deep knowledge in project management, design, implementation, and operations of large, complex, cloud-based automated information systems in various technical and functional environments. I have a good working knowledge of AWS and Azure cloud environments and specialize in case tools, content management, and translating customer business needs into technical solutions.
