Data Architect, Data Hobbyist, and Data Scientist
This is the super long version with EVERYTHING on it.
I am a data scientist, architect, and artist with expertise in the design, implementation, and maintenance of enterprise-scale business intelligence, data mining, data quality, and data migration projects. I have led teams of people through every phase of Enterprise Data Management, and I bring experience from high profile, large-scale clients such as NASA, SpaceX, the US Air Force and the US Senate. I have experience with the program management and development lifecycle standards required to run organized, repeatable, and successful data warehousing projects. I have personally designed data models, coded extract-transform-load (ETL) processes, built reporting architectures, and administered databases and application servers. I have matriculated into planning, architecting, and managing teams performing these tasks on increasingly large and complex systems.
