The most amazing...
...project I've worked on was migrating thousands of systems to the cloud on an epic scale.
Employment
Experience
- Migration of Veteran's Affairs to Microsoft Azure
I designed, built, and deployed over 1,500 Linux systems to Microsoft Azure for the Veteran's Affairs while migrating custom, built off-the-shelf software applications with limited documentation and few knowledgeable resources.
- Data Center to Cloud Migration
I designed and implemented migrations from on-premises (local or in the data center) systems—ranging from simple data systems to complex clustered applications—to AWS, all the while providing documentation on how each piece of the puzzle worked.
- ETL Cloud Pipeline
The artificial intelligence and machine learning team required a new ETL pipeline tool to deliver insights to applications.
I worked with dozens of departments, including cloud security, purchasing, operations, DevOps, and VP levels, from inception to delivery of this monolithic application for dozens of data scientists to provide near real-time data sets to applications.
