Meet the GEO Jobe Team! Developer Spotlight – Ken Doman, Senior Front-End Engineer

GEO Jobe has been serving our clients and partners since 1999 but you may not be too familiar with the faces behind the company. We thought it would be fun to introduce some of the talented crew behind the company to our readers, users, customers, and partners. We’ve shared a short Q & A with Front-End Engineer, Ken Doman, to help get to know him a little better and learn about our team. Doman is based in Chicago and works closely with our teams in Nashville, TN, and Biloxi, MS assisting in developing and expanding upon our world class GEO products.

Q: What is your role at GEO Jobe?

A: My job title is Sr. Front-end Engineer. I think the senior part is due to all the premature gray hairs I’ve earned from working in the geospatial field. As for a role, I develop, maintain, and troubleshoot GEO Jobe’s web products like Admin Tools and Mapfolio. I also develop web applications and tools using the ArcGIS Platform.

Q: What is your Educational background?

A: I have a Bachelor Degree in Biology from Rice University down in Houston, TX. The funny thing is, I started out as a computer science major, switched majors, and now develop software. As for my education in the realm of GIS and geospatial tech, that mostly came from the school of hard knocks.

Q: What were you up to before life at GEO Jobe?

A: About 6’2″ to 6’3″, depending on the shoes. Before GEO Jobe, I spent almost five years with Bruce Harris and Associates as a GIS Web Developer. There, I built web applications and solutions for clients across the country. Prior to that, I worked in Plantation, FL and Jacksonville, TX helping them with their GIS Departments.
Outside of the geospatial profession, I’ve been a high school chemistry teacher, a sewer inspector, a lab tech, and I’ve managed a manufacturing plant where I was the only employee. I’ve worn a few hats in my day.

Q: What attracted you to joining the GEO Jobe team?

A: GEO Jobe has an amazing reputation among the ESRI business partners. They have some of the most popular apps in the ESRI Marketplace. They’re making good things happen. Who wouldn’t want to be a part of that?

Q: Is there any specific project or task that you really enjoy(ed) working on? Describe a bit and why

A: I can’t say there’s one project at GEO Jobe that I’ve enjoyed more than the others, since they’ve all been pretty good. But I can tell you about a side project I’ve worked on over the years that I have enjoyed. That would be the ESRI REST Diagnostics tools.

ESRI REST Diagnostics ( are a set of browser bookmark applications (or bookmarklets) that I could run while looking at services in ArcGIS Server. They could tell me information about the services, show me maps, and even let me search for features and field names.
I eventually ported most of the tools over to a Chrome extension, called Map Services Enhanced. It grabs most of the same data as the Diagnostic tools without having to run a script each time. It made it quicker and easier for my coworkers to diagnose map service problems. It felt really good to help them out.

Q: If you were asked to take some training in the near future what would you like to learn more about?

A: Even before I started working with David Hansen, I had an interest in Machine Learning. I think it would be great to know how our future robot overlords think. But seriously, when you get past the hype, there are a lot of useful tools and insights to gather good ol’ statistical analysis.

Q: What do you enjoy doing outside of the office?

A: I enjoy spending time with my family and volunteering at my church. I also like cycling and exploring nearby nature preserves. I love cooking on the grill and in the kitchen. As a native Texan, I have rather strong opinions on what makes good chili and barbeque.

I have a taste things that are crazy spicy. If something on the menu is spicy, I have to try it. For instance, I have completed the Buffalo Wild Wing’s Blazing challenge. The only thing that slowed me down was that the wings that day were particularly meaty.
Q: Do you have a favorite geek resource or blog(s)?

A: So, so many. As a web-geo geek, I can’t help but mention Rene Rubalcava’s blog ( He is a beast at producing awesome content about the ArcGIS web platform. Another blog that amazes me every time is Adrian Roseblock’s PyImageSearch blog ( The guy does crazy things with images and videos using OpenCV and a few lines of Python.
As for other geeky resources, I like Make Magazine ( and their Instructables website (, because I’m a tinkerer at heart. For podcasts, my favorites are JavaScript Jabber ( and Shop Talk Show ( They’re both loads of fun and they help me keep up with the latest and greatest in web development. And for coding websites, I really like what FreeCodeCamp ( doing.

Q: What kind of computing technology or language do you prefer and why?
A: I like most web technologies. Anything that connects people and helps them to learn and communication is a good thing in my book. While I enjoy messing with JavaScript and CSS, I also enjoy tinkering with Python. It’s a great simplistic language, with a lot of power to create great tools and scripts. You even have the power to do things like import antigravity 😉
Q: If you weren’t in the career that you are right now what could you imagine yourself doing?
A: So many possibilities here. I think it would be fun catching and tagging alligators with tracking collars for science research. I’ve also enjoyed teaching and tutoring over the years, so I’d probably find something interesting to teach others.
Q:  I hear that you’ve authored a pretty popular coding book. Care to explain that one to us?
A:  My book Mastering ArcGIS Server Development with JavaScript is an advanced coding book for working with the ArcGIS JavaScript API. It starts off with making a simple map application, and ramps up from there. It covers creating your own map widgets, mobile development, implementing other libraries, unit testing, and even ArcGIS Online. It’s the book you want to reach for after you’ve done all the simple tutorials and want something more.

Q: Is there one or two things on your desk or in your office that you absolutely couldn’t do without?

A: That’s easy… my coffee cup. I wouldn’t be able to function without the dark, rich fluid that fuels my fits of coding. I’m more of a night owl, so I need coffee to make me functional in the mornings.

Q: Do you socialize on social media? I so, what’s your favorite resource to use and why?

A: I do to some extent. I’m regularly on twitter @raykendo. I save Facebook for friends and family. I read articles regularly on Hacker News and LinkedIn. As for other social media, I probably have an account on most everything, but haven’t dusted them off in a while.
