I've worked on a wide variety of iOS projects, implemented killer UIs, developed SDKs and have pretty much done it all (not actually, but I've done a lot). I'm extremely comfortable with developing any type of iOS application - so long as it works within the occasionally strict limitations Apple puts on their apps.

Android was the first mobile platform I worked with - and it's been a while, I picked up Android back in the days of 1.5. I've been working with Android pretty much every day since then, I've touched at least 50+ Android apps over my career and I'm looking to keep that number growing.

Rails has been the back-end of the vast majority of applications I've worked on. Apps that I've worked on have received more than 1,000-2,000 requests per second and I developed from scratch the back-end for Canada's largest iBeacon network.

On average I spend 2-3 hours per day working with Unity related projects. I've released multiple mobile games through Unity and feel relatively confident with most Unity use cases, ranging from basic scripting to custom editor modules.

I lead our mobile team through iOS and Android development. PIA is a VPN company, and keeping up to date with the world of cyber security was crucial. As the lead developer, I managed our mobile teams weekly tasks, identified areas to improve, and worked regularly on Android development and to a lesser degree iOS development.

Worked to develop security centric applications. TunnelBear mixes incredibly thorough and strong encryption cycles with the simplest and most appealing UI you could imagine. The goal was always to create the world's simplest security apps that you could install and get running without even realizing you were using a security app.

I started off as the first technical hire at the company where it was my job to build both their iOS and Android apps in less than a month. From there, the company grew, I dealt with managing hiring, building out new products and managing parts of the server.
In this time, I worked to create Canada's largest iBeacon platform, worked closely to implement features for PoS systems in Canadian retailers and continued to develop our mobile apps... Until the company was eventually acquired by Yellow Pages.

Worked as the initial developer for the Android version of Say the Same Thing. To the best of my knowledge, the app is no longer available (it may or may not work in the Play Store).
I developed the app along side a member of the band OK Go who create the iOS version of the app initially.
My some strange chance, the app was the 50 billionth app downloaded from the App Store and was featured in an article from Apple as a result.
