Experience
Masters of Scale Mobile app
https://mastersofscale.com/The Masters of Scale podcast is downloaded 20 million times per month and comes with a companion app that delivers the content in a course structure. The first version of the app was released in 2021. When I joined the project, the product was essentially a prototype with unappealing acquisition, retention, and conversion statistics.
As a de-facto CTO for the organization, I implemented a program of improvements to the UX and engineering practices and designed and delivered analytics processes and capabilities that helped the company significantly improve on all these measures. The project was primarily a mobile project, but I also managed some of their website projects and deliverables.

Food Diary Mobile App
https://ieatbetter.comIn 2012, The Power of Habit, by Charles Duhigg, revealed Harvard Medical school research showing that a food diary alone is enough to positively influence your health. Microsoft had a program for employees to develop mobile apps for their operating system, and so started Food Diary.
After five years and five million downloads, I feel I have helped people live better, healthier lives while creating a sustainable business at the same time.

Refinery Inspection App
The Refinery Inspection application is used for factory and oil rig inspections. It was initially developed for iOS, so I worked with the company to port the application to Xamarin Forms for use on multiple platforms. We also delivered several extensions and additional modules. Quality, stability, and ease of use were the priorities.
Xamarin Forms for Medical Devices
https://perceptivesol.com/Implemented a production-quality version of a medical imaging application in Xamarin Forms for UWP, Android, and iOS.
The team working at this Toptal customer developed a proof of concept based on a website developed internally. When management approved the production quality implementation, they contracted with me to get it done. Part of the project involved getting the team up to speed on contemporary software design principles. The project was organized with scrum and with daily standups.
