Significant Personal Projects

Hindsight (2021-)

Hindsight is a log viewer designed to show you what happened on a given date, using private databases that you supply. It makes it easy to follow events in chronological order, grouped by source.

Reverse engineering experience includes Adobe Lightroom's catalogue, EXIF / QTFF metadata, log formats of Adium, Colloquy, Google Hangouts, Facebook Messenger, Pidgin, MamIRC, Matrix, mIRC, The Lounge (formerly Shout), X-Chat / HexChat, Android's Call+SMS DB, and the Windows Phone 7 filesystem (TexFAT).

API experience includes Bikeshare Toronto, GitHub, CalDAV / CardDAV, IMAP, FitBit, Netflix, Nintendo Switch Online, and Presto.

SocialLink (2020-)

SocialLink is a custom social networking client - it presents everything grouped by person in chronological order, regardless of the underlying account or service used to initially post. Rather than following John Smith on a bunch of individual platforms, you can simply follow John Smith and see everything they post, with no algorithmic filtering.

Reverse engineering experience includes DeviantArt, Facebook, Instagram, Pixiv, Twitter, and Tumblr. API experience includes Reddit and YouTube.

Internet of Things (untitled project) (2015-)

I developed a system for controlling electronic devices (lighting, HVAC, etc) inside a home and autonomously making decisions for those devices based on relevant data collected from a variety of sensors.

Ruby on Rails, PostgreSQL, Redis, and nginx are used to power the core platform itself, with React.js + JSX used for the frontend. Ruby/AppleScript (macOS data collection), Java (Android WebView syscalls), C (custom Arduino-based sensors), PowerShell (Windows client keepalives), Ash (embedded Linux scripts), and Node.js used for smaller components.

Reverse engineering or documented API experience on this project includes iCalendar, IMAP, Insteon, LIFX, Google Cast, matrix.org's Synapse, Nextcloud / Owncloud, Particle Photon, Philips Hue, Sony Bravia, Ubiquiti mFi, Vizio SmartCast, and vCard.

Japanese Language Study Tools (2014)

Built a collection of tools to help people learn and study for the Japanese Language Proficiency Test (JLPT). While the tools only cover JLPT N4/N5, I found that they filled a significant gap in existing study tools. Word lists and flashcard study tools exist everywhere - however, speed-reading kana, adjective conjugation, vocabulary formed from specific grade kanji, and kunyomi or onyomi quiz tools are rare.

Mobile App Development (2012-2013)

In May of 2012, I created three applications for Windows Phone 7.5, called DineSafer, JLPT Flashcards, and Crossworder, using C#. During January of 2013, DineSafer and Crossworder were ported from scratch to BlackBerry 10, using Qt Cascades, QML, JavaScript, and C++.

Symphonary (2011-2012)

I designed and co-developed, along with Xingzhe (Travis) Lu, a program to teach people to play various musical instruments with the assistance of a computer. Using a custom hardware sensor in conjunction with an Atmel AVR that's attached to a musical instrument, Symphonary allows the player to see (in real time) what fingerings they're pressing on their instrument, and receive a numerical grade based on their performance.

Symphonary's client is written in C#, using WPF for the GUI components, while the hardware runs code written in C. More information, including source code and images, is available here.

SimplePost.ca (2012)

SimplePost was a free service that allowed you to send physical letters to your elected federal officials. A user could enter their message and address, which would find their region's MP, senators, and other cabinet members, and the site would create physical printable letterhead made out to each individual that the user picked. Because letters to the federal government don't require stamps, the site allowed you to easily send paper letters (which are generally regarded as being more effective compared to email), without the use of stamps or envelopes, thanks to the magic of origami.

I designed the site and branding, and co-developed the frontend, using CSS, XHTML, and JS.

More details, including, screenshots and a more elaborate summary are available here.
