Work Experience


2008 - PRESENT
Fictorial LLC
  • Developed iOS apps for bespoke games, including Darts, which has been installed on over 15 million devices and was #1 in the App Store in December 2008.
  • Created other bespoke games including RPS World Masters (a multiplayer rock-paper-scissors game) and Lexatron (a word game mixing racing and strategy elements).
  • Developed Visuality360 for Global Apparel Network, an enterprise iPad app that provides retail chains with a way to direct store layouts and perform visual (photo-based) audits conveniently and easily.
  • Developed Furry Face Off, the ultimate app for those who love to show off their pets. Allowed users to enter their favorite pet photos in weekly contests.
  • Developed FameTag, a social media and interaction app that shows users the words their friends use to describe them and what makes them "famous".
  • Developed Picture That, an addictive multiplayer photo guessing game.
  • Developed Chumkee, a social photo sharing platform/app that transcends language and location through video and photo conversations. Used Unique UX, localization, real-time translation, and web services.
  • Developed Lexatron, a word race game in which users snake a path from one corner of the board to the other by forming words on the board using only their own letters. The player that reaches the opposite corner first wins the match.
  • Darts is a realistic 3D darts game for iOS that lets users play cricket, 501, and more. Darts was released in 2008, went #1 on the free charts, and has been downloaded millions of times.
  • Developed RPS World Masters, an addictive online-only version of the classic rock-paper-scissors game. Users will be automatically paired with random opponents from anywhere around the world.
  • Developed Apprentice, a cross-platform mobile-hybrid app and platform (back-end too) for internships and other field experiences. Implemented HIPAA/FERPA compliant back-end storage, a custom iOS-JavaScript bridge (no PhoneGap/Cordova), audio recording and playback, visualization of student progress, and more.
  • Developed Balloon as a MVP for students in the DreamIt accelerator program. Wrote this 4-week project from scratch to provide the neat twist of getting friends together for impromptu events.

MVC Library for Single-page Apps

I created a lightweight model-view-controller (MVC) library for single-page applications. This library was developed before the rise of React but shares similar core concepts, albeit with a reduced reliance on the virtual Document Object Model (DOM). In this MVC library:
• A model represents a named collection of key-value pairs.
• A view controller acts as an intermediary between a rendered view of the model and DOM event bindings. It handles the methods responsible for modifying an instance of the model.
• A router maps URI fragments to handlers, typically loading models from a data source and creating view controllers for displaying and updating them.
• A model acts as an event emitter and notifies registered listeners whenever its underlying properties undergo mutation.

Mixed Reality Billiards

This was my Master's thesis for computer science. Mixed-Reality Billiards is an amazing project that mixes elements of computer vision with human-computer interaction. MRB allows users to practice playing virtual billiards using real physical billiards cue sticks and balls. It was published in ICME 2008 and presented in Germany.

Lexatron is a 2-player word game with race and strategy elements. Brian invented the idea, designed all the graphics, and developed, tested, and deployed this app.

Python – Simulation Tool for iOS Project

In 2008 I used Python to create a Monte Carlo physics simulation for a computer controlled opponent for a darts game for iOS. The simulation threw millions of virtual darts, recorded where they landed and the parameters that got them there, and generated Objective-C code that included all of this information for use at runtime by the computer-controlled player.

Python – Web Admin Tool

I’ve used Python for web development back-ends as well. The most recent example is an ongoing client project that requires a “web admin portal.” This work allows the client/admin to log in to a custom website and query a database. The tech stack for this back-end portion of the project is, Records, and Postgres.

Python – Game Development
I’ve used Python for game prototypes and open source projects as well, using Cocos2d (before it’s port to iOS became hugely popular) and PyGame. For PyGame, I’ve created a UI toolkit for simple needs: things like buttons, scrollable areas, text rendering etc. That’s up on GitHub: See also

Python – Open Source Contributions
I added transaction support to Records which is a very popular Python library for making database querying very "Pythonic."

Python – Object Database
I’ve also used Python for various experiments including a rudimentary database and supporting code (keypath).
