Brad Derstine Resume

With over 17+ years of IT experience, I’ve made a career out of learning the technologies and tools to accomplish some of the most dynamic IT initiatives. I believe in using the right tool for the job so I keep an open mind, continue researching, experimenting, and testing my ideas using many of the latest cloud technologies. I’m looking for a company that will appreciate and take advantage of this experience and challenge me to expand my knowledge and keep growing as a professional.
