Hank Preston

Principal Engineer

Learning and Certifications

Hank’s two passions are technology and theatre. Bringing them together drives him towards a borderline obsession on creating entertaining presentations, labs and demonstrations that breakdown complex technology topics for audiences. After spending several years working on and behind the scenes on stage productions, what started as a hobby turned to a profession when Hank entered the IT industry with a focus on web and database development and engineering.

Drifting from development into infrastructure engineering brought him to Cisco as a Systems Engineer, focusing on Data Center and Cloud Architecture for large enterprise customers.

And after six years as an SE, Hank has taken up the mantle of a Developer Evangelist with DevNet where he can focus full time on reminding everyone that technology can and should be fun to work with.

Hank holds a Master Degree in Information Systems as well as several certifications including CCIE R/S 38336 from Cisco.
