Ted's talk will kick off an afternoon of talks featuring JanusGraph. Details forthcoming soon.

Ted Wilmes (Oklahoma City) @trwilmes

Ted Wilmes, Data Architect at Expero, is a graduate of Trinity University where he studied computer science and art history. He started his professional career at a not-for-profit research and development institution where he performed contract software development work for a variety of government and commercial clients. During this time he worked on everything from large enterprise systems to smaller, cutting edge research and development projects. One of the most rewarding parts of each of these projects was the time spent collaborating with the customer.
As Ted’s career continued, he moved on to an oil and gas startup and continued to dig deeper into the data side of software development, gaining an even deeper interest in how databases work and how to eek as much performance out of them as possible. During this time he became interested in the application of graph databases to certain problem sets. Today, at Expero, Ted enjoys putting his deep knowledge of transactional graph computing to work as he helps customers of all types navigate the burgeoning property graph database landscape.
Outside of work, Ted enjoys spending time with his family out-of-doors, listening to and playing loud music, and contributing to the Apache TinkerPop
project as a committer and PMC member.

He enjoys cycling, sailing, skydiving, and many other adventures when not in front of his computer.

Mike Downie (Bryan/College Station)

Mike Downie, Technical Lead at Expero, is driven to solve technical problems in the most practical way possible. To do this well he developed a diverse set of skills to truly understand the problem(s) at hand and a depth of technical knowledge to create great solutions.
Lifelong interests in technology, math, and science and that drive to solve problems led Mike to pursue a Computer Science degree at Texas A&M. He wasn’t content to learn about software in a classroom, he wanted to apply concepts in real-world settings as soon as possible. His final three years of college he worked professionally developing software. First as a co-op student for a (then) national telecommunications company and later part-time for a software consulting company. This ‘dual education’ allowed Mike to graduate with a strong academic foundation and the practical skills to apply his knowledge.
After completing his degree Mike continued to work for the consulting company, helping the company grow from 4 employees to more than 60 over the course of a decade. He gained expertise through success on a diverse set of projects. Project work included data acquisition and control, database applications and user interface design. During this period Mike also built software teams, studying software project management, estimation, requirements gathering, application lifecycle management and learning to effectively mentor junior developers.
Mike’s most recent work includes database design and front-end development for enterprise resource planning systems. He continues to look for difficult problems needing great solutions. What makes a great solution? He says first and foremost it has to work well, meeting both the functional and non-functional requirements. A solution can’t just work it has to work fast enough, be intuitive to the user and be maintainable by the developers to be great.

Josh Perryman (Bryan / College Station) @joshperryman

Josh Perryman likes to play with data. Oftentimes this is implementing proprietary algorithms closer to the data for performance or scale. Sometimes it is ad-hoc investigation and analysis, a sort of exploratory querying. A few times he’s been able to leverage his experience with data engines for dramatic performance improvements. But the real joy is designing a schema for both functionality and performance, one which increases the productivity of other developers and enables a technology to solve new problems or deliver new value to the business.
But technology isn't just data, and he does more than just play with data. He’s worked with high performance computing (HPC) environments, taking computations from hours to minutes or seconds. He has built visualizations which deliver new insights into complex data domains. He’s managed technology personnel, both directly and indirectly, to deliver technology solutions. He’s have put together more types of technology components, software and hardware, than can be counted, because one of his fortes is solving problems by building sustainable systems.

Trey Wilson (Dallas)

As a software consultant for Expero, Trey Wilson focuses on getting real code working quickly. Trey loves to work with the newest technologies, but only when they serve to achieve a pragmatic goal.
As soon as the “middle-of-nowhere” town that Trey grew up in had the Internet, he taught himself to program and hasn’t looked back since. He has programmed everything from displaying real-time geospatial communications data to image recognition using deep learning algorithms. The quickest way to get Trey interested in a problem is to say “This looks difficult.” Trey enjoys traveling to new cities to see if they have any good craft beers, reading up on esoteric subjects in case they ever become useful, and cooking like an amateur.
