    Most of my professional experience is in SQL development with American Express. The project lasted two years and my task was to convert all of our TeraData scripts and stored procedures into Hive on an AWS environment for LARGE amount of data processing and reporting to the regulatory bodies of Mexico, France, Italy and The Netherlands. I created a self-contained Python package to neatly convert all of the newly-generated Hive data into XML for each jurisdiction. In addition, a lot of my development experience is in PHP, JavaScript, building reactive SQL-database driven web applications for the marijuana industry in Colorado. I also have experience administrating many different deployment configurations for enterprise level customers. Most of my experience is in IBM z/OS Mainframe, Windows Server 2019, and RHEL. Further, the amount of projects located on my Github show my versatility in development technologies. I have also written technical documentation and developed software for IBM, Trimble Geospatial, 421Hemp, and Apollo Decentralized Asset Exchange. This shows my ability to work with both huge, enterprise level customers as well as small 1-5 person startups with the same degree of finesse and skill. The experience in highly regulated industries I possess gives me a keen focus on tasks where the level of attention-to-detail is paramount, and as an added bonus my OCD prevents me from leaving any task unfinished or subpar.
