Lead Developer focused on Android

Download Resume
Julien Guerinet

I am an avid developer mainly focused on Android mobile development. I have been working on the Android platform for over 6 years, constantly learning about the new technologies in order to keep my projects modern and up to date. Recently I have switched to doing all of my Android development in Kotlin. I have also developed iOS apps and have dabbled in web development, specifically TypeScript and Node.js.

For the past two years I managed a team of six mobile and web developers at the Ottawa Hospital mHealth Lab. Doing so gave me my first experience in management, while still being part of the technical side as I continued to develop during this time.

Before my time at the Ottawa Hospital mHealth Lab I cofounded a startup with a couple of friends from McGill and a physician from the Ottawa Hospital. Sigvaria was created in 2014 to create web and mobile solutions for the health sector. One year later, we were absorbed by the Ottawa Hospital and rebranded as the Ottawa Hospital mHealth Lab.

I am currently a freelance Android developer looking for my next big project. In the meantime I have been working on personal projects and deepening my knowledge on all the technologies mentioned above.

I have used the following languages and platforms:

  • Java (8 years)
  • Git (8 years)
  • Android (6 years)
  • Kotlin (2 years)
  • Swift (2 years)
  • iOS
  • Objective-C
  • TypeScript
  • Node.js

Libraries

Suitcase

Suitcase is a set of useful Android utility classes and functions. It was built for Kotlin, and covers multiple aspects of Android development such as coroutines, dialogs, lifecycle components, and more.

Morf

Morf is a form generation library. Built for Kotlin, it allows you to create highly customizable programmatically generated forms.

Weave

Weave takes an online CSV file and parses its content to produce String files for Android, iOS, and the web. This allows you to use the same Strings for the same app across multiple platforms.

Projects

CANImmunize January 2013 - January 2019

CANImmunize is a free digital tool for Canadians that securely stores your vaccination records and helps you get vaccinated on time. I was initially the QA tester for the first iOS version of the app, and was then tasked with bringing it to Android. We released the Android version in March 2014. Up until January 2019, I was the main Android developer, a secondary iOS developer, and the lead of the development team for the app.

MyMartlet January 2014 -

During my studies at McGill I started working on an unofficial open-sourced McGill app with a group of friends for a class project. I took on the role of project manager and lead Android developer. We released MyMartlet for Android on September 2014 and I am still actively maintaining the app.

The Ottawa Rules September 2015 - January 2019

While working at Ottawa mHealth, we developed The Ottawa Rules, an app containing clinical decision guidelines for physicians. I developed the Android version and part of the iOS version.

SafeLiving January 2016 - January 2019

Another Ottawa mHealth project was SafeLiving, an app designed to help transplant patients manage vaccinations and medications. I developed the Android version and most of the iOS version.

AdForum Worldwide Summit March 2014 -

I developed the Android app used during the AdForum Worldwide Summit. I worked with the designer and iOS developer to port over the iOS app to Android, and give it a new modern look.

Personal Interests

Pixel
This is Pixel, my month old puppy. He is a beagle-mix rescue dog who lived the first three months of his life on the streets of Greece before being brought to the freezer of the Earth, Canada. He is simply the best dog that has ever lived, objectively speaking. If you are a dog owner, I am sorry to be the one to break this to you.
I am a big fan of The Office, and have therefore taken on the thankless job of hosting a weekly podcast where I, along with my co-host Lindsay Wilson, review each episode. You can find out more (and even subscribe) here. We guarantee laughter, even if it's only our own.

Ski
I have been skiing since the ripe age of 2. I was fortunate enough to grow up near the Swiss Alps and have therefore been spoiled with Alp-ine skiing every year since 1994. In 2016, my friend Connor and I set a goal to ski in a different country every year. Over the course of my lifetime, I have skied in the United States (Colorado, Vermont), Canada (Alberta, British Columbia, Ontario, Quebec), Switzerland (Crans-Montana), France (Chamonix, Le Grand Bornand, Les Portes du Soleil) and the UAE (Dubai).
