I started SVEN Studios in 2012. In the first three weeks, I learned Java, learned the Android frameworks, learned Google App Engine and built a realtime synchronous JSON based Client-Server architecture for WordHero and shipped version 1.0 of the puzzle game. WordHero went on to be featured on Google Play several times and receive millions of downloads.SVEN Studios now has several multi-player synchronous puzzle games for the Android platform. Everyone plays the same puzzle at the same time with realtime leaderboards at the end of a 3 minute game round. Games include WordHero, Anagram Hero, WordSearch Hero and Math Hero with more coming. SVEN Studios uses a hybrid solution of Google App Engine and Node.js on the backend.Approximately 80% of the client code is pure business logic for JSON based Leaderboards, Friends list, Help and Settings with extensive use of threading to offset load time slowing the GUI. The game the users play comprises the other 20% of the code base of each 'game' which is typically outsourced along with sound and graphics work.

Responsible Architect for the Core Funnel of the Wayfair Android app. Core Funnel includes browsing products, viewing product details, adding to cart and purchase flows.

As one of the Core Platform Architects, I introduced multiple software patterns on which the core of the Wayfair Android app is built. These include network data caching, repository pattern, data validation, network error characterization and handling, global error handling, Load/Content/Error pattern and network state monitoring with retry.Other duties included embedding within development groups on an as-needed basis, interviewing candidates, mentoring junior developers, creating presentations and training on new software patterns so they can be rolled out across development groups within Wayfair.
