About Me


I am currently a principal software engineer at Talen-X. I was part of a small startup that developed multi-million dollar product lines and was successfully sold to a larger company.

As a quick learner with nearly a decade of experience in industry, I am a productive and valuable asset to my professional engineering team. I have spent years creating new products, fixing bugs, and adding features to existing product lines.

Work Experience

Talen-X, Ankeny, IA 2017-Current
Principal Software Engineer

Our great team (of 4 engineers, a CEO with capital, and a few sales guys) split from PreTalen, which was growing head count doing contracting work for the government. We developed BroadSim, a GNSS simulator with support for military encrypted signals, in our basements. Now we're taking BroadSim to the next level in our Ankeny office.

PreTalen, Ankeny, IA 2015-2016
Software Specialist

Working with a great team, I designed and developed new products and added features to existing ones. This included adding 50+ GPS receivers to a C# application that allowed testing the receiver performance in various scenarios and simulated denied environments, training other employees, on-site visits, and new product development.

Ag Leader Technology, Ames, IA 2013-2015
2 years - Software Engineer on the Advanced Development Team
I took the lead on developing the Remote Support feature for the company [Link], and added numerous new features to two of its products: their flagship Display (an embedded Qt application), and AgFiniti (a C# cloud­based web application).

Iowa State University, Ames, IA 2010-2013
3 years - CprE Instructor, Teaching Assistant, Research Assistant
I have been a teaching assistant for CprE 388, a course on iPhone development I helped design during my undergraduate career. In the summer of 2011 and 2012, I was in charge of running the lecture and monitoring the labs for CprE 288, an embedded systems course that uses the iRobot Create platform and gives students experience with C programming and the ATmega128 processor.

Chaddington Software Studio, LLC, Ames, IA 2010-Present
Ongoing - Part-time Entrepreneur
Wanting to stay in Ames and enjoy my freedom before graduate school started, I spent a summer figuring out how to start an actual legal business (LLC); I decided I would see how much money I could make on my own, with high hopes of becoming a multi-millionaire and hiring my friends from non-computer related fields (as they were having a hard time finding work). I honed my web development skills, learned a lot about myself and how to keep myself motivated, and ended up creating a few streams of income, albeit small streams. I'm not Mark Zuckerberg, but I was able to create a knock-off of his Facemash in a day. I also fiddled around with Apple's AppStore and the Android Marketplace and have a series of applications that bring in some money. I also did some freelance work on the side. I still spend a weekend here or there growing my business.

Priority 5, Ames, IA 2009
3 Month Developer
Priority 5 is a small startup company located at the ISU Research Park. At Priority 5, I designed and developed a phone transcription product on a team with two other Agile developers. The project consisted of doing a market survey of available medical transcription software, definition of the project, risk analysis, and cost estimation. I was responsible for researching VOIP (Voice Over IP) technology, deploying a VOIP based PBX (Public Branch Exchange) using Asterisks. The team benefitted from my research and development skills, along with my expertise with CMU's Sphinx speech recognition engine. Adding Sphinx to the dial plan logic I implemented using Asterisks, our team was successfully able to create a turnkey product that could transcribe phone speech in a way similar to Google Voice.

Intermec Technologies, Cedar Rapids, IA 2008-2009
7 Month Software Engineer
Intermec is a mid-cap technology firm that specializes in developing mobile devices for business use. At Intermec, I was part of a team of twenty engineers who were integrating Windows Mobile on a custom set of hardware. During down time, I taught myself C#; which became an asset to the company later in my stay. I began teaching other employees the language, and we used it to develop test code much faster and increase our code coverage. I helped encouraged knowledge sharing through WikiMedia software with friendly competition; I would send out statistics on those members of the team that contributed the most in a given month. This knowledge sharing helped create a rising tide, with less skilled members of the team learning from the more experienced users, thus, making our team more productive. I also created various departmental applications for automated reporting and test automation.

Rockwell Collins, Coralville, IA 2007
3 Month Business Intern
Rockwell Collins is a large-cap corporation specializing in commercial and governmental aviation electronics. At Rockwell, I was taken under the wing of a management team overseeing groups of operators who were hand soldering specialized parts on circuit boards. Although only a freshman, my knowledge of Visual Basic proved extremely valuable to the management team. Individually, I defined, developed, and tested over 6 projects that automated reporting, mined data to reduced defects, and allocate staffing depending on scheduling need. My greatest achievement at Rockwell was automating managerial paperwork. At a rate of 1 man-hour per manual report, one of my three reporting automation programs continues to save the company 20 man hours of managerial labor costs per week.
