Experience

FarOut Guides

http://www.faroutguides.com

A mobile app used by long-distance hikers and cyclists on trails worldwide for navigation, guide information, and communication.

I created the iOS app Circa 2011 and was the sole iOS developer until around 2020. I also designed our cloud back-end system for iOS and Android using the Parse server and wrote much of the cloud code for data validation and server-side functions.

Until around 2019, I handled all iOS-related customer support interactions directly with customers and continued to handle more complex support situations until 2021. I created a macOS app for internal company use as a content management system, customer support tool, and account management tool.

I continue to advise our current developers and aid in systems development as a part-time developer while pursuing other projects.
