The most amazing...
...project I've built is called RichTextView—an open source iOS project starred at least 1000x that can render HTML, Markdown, LaTeX, and YouTube videos.
- Facilitated a major database migration from the v2 version of the app (JSON and plist) to v3 (Realm, now Atlas Device SDK), unblocking a major version upgrade.
- Fixed the subscription pricing in the app to be dynamic and introduced the ability for users to restore their purchases.
- Added tracking around video sharing and various other issues around the app to debug and fix those bugs.
- Introduced support for Bluetooth remote control of the iOS app for script-based auditions.
- Debugged missing take videos and AVFoundation errors.
- Added support for users to share their roundtables via a share code.
- Enabled the ability for special users to create custom topics with custom color tinting and badging for users that join those topics.
- Fixed general bugs and updated the project to the latest XCode.

Senior iOS Developer
- Participated in an entire iOS app rewrite, moving 30% of the project's code to Swift within the first six months.
- Championed a week-long project to streamline and standardize our dependency management system, moving from a mixture of Carthage and static dependencies to CocoaPods, removing approximately 100,000 lines of code in the process.
- Contributed to the rewrite of the entire question experience on iOS to Swift, improving the app's weekly crash-free rating from an all-time low of 96.5% to 99.5% and the App Store rating from 3.2 to 4.5 stars out of 5.
- Established the team's accessibility standards and Swift code style guides.
- Led the technical planning around re-architecting the entire student classroom experience on iOS.
- Participated in a complete overhaul of our iOS network engine, moving from Objective-C and RestKit to Swift, Codable, and PromiseKit.
- Championed a week-long project to standardize and streamline our UI/UX process on mobile, including colors, font sizes, and images.
- Worked with the rest of the department to bring a vast array of web features to our iOS app, including tournaments, Top Hat Test, and third-party questions.
- Worked with a team of three developers to manage five iOS applications for the luxury homes market, developing features that led to an 80% engagement rate on our apps.
- Utilized polygon drawing and correction algorithms to enable users to draw custom boundaries on a map, in order to filter particular regions in a real estate search.
- Architected major portions of the agents app, adding the ability for agents to see and interact with their clients, as well as view their own listing and search history.
- Strengthened the Swift API layer in our apps to better communicate with and translate Thrift data structures coming from our servers.
- Worked on the messaging portion of the flagship iOS app with eight other iOS developers and approximately two dozen other developers, project managers, and designers.
- Developed a feature that allowed LinkedIn employees to message their coworkers and add them to group conversations, working with an Android and back-end developer.
- Enhanced the messaging experience by enabling users to see the content of URLs sent in the app by showing a basic image, title, and description along with inline YouTube videos.
- Enriched the user experience by modernizing the loading animation across messaging.
Mobile Application Developer
- Used iOS Objective-C, Lua, and C++ to develop a contest feature for Sculpt+, a 3D-intensive social media app where users could share self-created 3D models.
- Updated the Android app to be Gradle-based, reducing build speeds by up to 50%.
- Improved the internal Kalpana 3D framework which was used by multiple Autodesk apps.
- Used the Appcelerator framework to work on the Save.ca hybrid mobile application, part of Canada’s largest online shopping savings and deals ecosystem.
- Performed routine bug fixes and updated the app to iOS 8 and Android Lollipop.
As the sole developer, I was involved on the ground floor of this project, from creation to deployment to maintenance, as well as putting it in the CocoaPods Specs repo so that anyone can integrate it into their projects.
