Open Source Projects

Tiime |

The first iOS app I built from scratch, Tiime is a clock that displays time in non-standard ways, and allows for user customization of the app’s icon, colors, and fonts.

  • No third party dependencies
  • Used the Coordinator pattern for the app’s architecture
  • Added theme customization using UIAppearance and other UIKit methods
  • Implemented timers and date math to calculate the different clocks
  • Beta tested through TestFlight, and released to the iOS App Store

Plain Pasta |

My first macOS app, Plain Pasta is a menu bar utility that strips any styling from text on the clipboard, keeping it neat, tidy, and plaintext.

Work Experience

Jamf Software

iOS and macOS Developer (March 2019 – present)

I joined Jamf because I wanted to develop iOS and macOS software that would impact people, and it did not disappoint. Jamf’s software is running on thousands of devices across the globe. I wore a few hats at the company, first working on a client-focused iOS and macOS app, then moving to work on a more low level macOS application with a command line interface — the backbone of Jamf’s Mac management platform.

  • Lead efforts to greatly improve the Accessibility features of Self Service, Jamf’s primary user-facing macOS app
  • Helped maintain and improve my team’s multiple testing suites and CI/CD workflows
  • Took ownership of an internal server-side Swift project
  • Effectively investigated and implemented multiple large and small features and improvements to the codebase
  • Worked across countries and time zones with coworkers on my team, and outside my team

iOS Developer (July 2018 – March 2019)

As Q3’s sole iOS developer, I maintain Q3’s multiple existing iOS apps and libraries, write new apps based on the business’s needs, and help decide the direction of mobile development for the company.

  • Created a brand new iOS app that displays contact information for all employees in the company
  • Updated or retired the company's many existing apps that had been languishing
    • Migrated analytics, crash reporting, and beta deployment from Mixpanel, Fabric/Crashlytics, and DeployGate respectively, to Firebase
    • Added Carthage support to the company's iOS libraries
    • Removed unnecessary external dependencies, and replaced them using native UIKit / Foundation APIs where possible
    • Improved the build and deploy process for apps that rely on multiple environments (dev, test, prod, etc.)
  • Volunteered to manage our Jenkins server, and have begun updating and improving our build processes for both our web and mobile applications
  • Begun building a brand new microservice API using Node.js and TypeScript
  • Been part of technical interviews and onboarding for new developers joining the team

C.H. Robinson

iOS Developer (July 2017 – July 2018)

After a three month stint as a web developer for C.H. Robinson, I moved onto the mobile team, and took over all development of the company’s two iOS apps. Having not done any iOS development prior to this, I needed to learn quickly to keep the apps functioning, and deliver new features.

  • Learned Swift and iOS development, and was pushing code to production in less than a month
  • Implemented a complex system for monitoring and reporting a device’s location while the app ran in the background
  • Internationalized one of our apps for use in Europe, implementing 7 new language translations, updating the UI to be more adaptive, and made significant updates to the app’s networking logic to address multiple latency issues.

Full-Stack Web Developer (April 2017 – July 2017)

I was hired for C.H. Robinson’s HatCHRy program — a three month intensive on-boarding program for new developers — where I learned all about the company’s business and technology. It was here that I learned C#/.NET, and used it to develop an internal backend service that sent email notifications upon successful upload of accounting documents.
