Tier One Leadership

Aaron Bilger

With over 15 years of experience, Aaron Bilger's expertise ranges from enterprise database and web development, to FPGAs and deeply embedded . At the high level, Aaron has architected and implemented systems such as web-services based content management system for LED billboards, and a web-based vehicle tracking and alert system handling millions of GPS location tracks per day. Wearing his embedded hat, he has run the gamut including complete 32-bit CPU and system emulation to replace old hardware, high speed video switching, wired and wireless keypads, point-of-sales, and casino games.

Aaron has a BS in mathematics and a MS in computer science from Purdue University.  He is also inventor on two US patents.  In an alternate universe, Aaron's interests may have found him in experimental psychology or military strategy. In this reality however, he is most fond of any manner of software and systems engineering - with particular adeptness discovering and working around errata or solving challenging optimization problems given constrained resources.


Kyle Howell

Kyle is a graduate of Georgia Tech with a B.S. in Computer Engineering. A long-time computer hobbyist, he entered his first programming contest at the age of 8, sold his first computer program at the age of 15, and started his first freelance contract at 18. Before joining Tier One in 2009, Kyle’s career focused on embedded video processors, including time at Barco, EGT, and Arris. Outside of the office, Kyle’s interests include home automation and a healthy dose of tennis.


David Spiller

David Spiller has been a technology consultant since high school and a life-long engineer.  Shortly after obtaining a bachelor’s and master’s degree at the Georgia Institute of Technology, he joined Tier One.  In this capacity, David has been a major contributor to products that millions of people use regularly, including a debit PIN-pad and a beverage-dispensing machine.  His expertise includes cryptography, system architecture, Board Support Packages (BSPs), and optimizing systems for very low power.  When time allows, his interests include skiing, sailing, and building high-power rockets.


Tom Tooley

Tom Tooley earned his BS in Electrical Engineering from the University of Notre Dame, and later earned his MBA from Georgia State University. He has been involved in the development of electronic design since graduating college, and is credited as an inventor on 6 patents. He has a passion for getting electronic designs right the first time, while also managing risk when a learning opportunity presents itself.  When not skiing or sailing, Tom enjoys the tapestry of a good printed-circuit board layout, the serenity that a quiet switch-mode power supply offers, and the majestic beauty of a DRAM bank that fully exploits its throughput potential.
