Hey, thanks for visiting my site, I’m Donn Felker.
I design and develop software, author various books on Android, develop open source software and write about various topics that interest me. I’ve been developing software for nearly 16 years and running software based businesses for the last 7. I’m a Google Android Developer Expert (Android GDE). I’m the founder of Caster.IO, a bite-sized Android development video training company. I’m the co-host of the Fragmented Podcast – a podcast for Android Developers. I’m the author of Android Application Development for Dummies, Android Tablet Application Development for Dummies and I’ve contributed a chapter to the Android Developer Tools book and written for various other technical publications as well.
Other than Caster.IO I also consult for various companies. Agilevent is my software company that specializes in Android consulting and various server-side technologies. We help most companies with Android implementation, improvements, app performance and user acquisition and retention. Personally, I’ve helped develop some of the largest and most popular Android apps in Google Play which include: Groupon, MyFitnessPal, Eventbrite and GetHuman (as well as a vast array of other apps) and the Poynt smart terminal. I’m currently helping the Realm team conquer the mobile market with their new mobile database (a replacement for SQLite). I also have experience in NodeJS, MongoDB, Ruby on Rails, MySQL as well as some of the Microsoft stack as well, such as: AZURE and ASP.NET MVC. If you need help with any of these technologies or merely need some advice in regards to a problem you’re having please reach out and let me know. I’d love to help.
I am originally from northern California, but I now reside in central New Jersey (equidistant between NYC and Philidelphia). When I’m not working or playing with my kids or hanging out with my wife, I’m usually enjoying a good CrossFit workout our tinkering with a new technology (IoT currently).
Please feel free to contact me if you have any questions, ideas or even if you just want to say hi. If you’re in the greater New York City or NJ area visiting, please send me an email and I’ll do my best to meet up with you for some coffee or a lunch.
