Work Experience
Senior Lead Developer
2013 - PRESENT
Erasys GmbH
- Addressed serious stability and performance issues in the codebase (originally from an external dev, it was now in-house) by substantially improving the architecture; also installed a custom UI framework that reduced the need for fragile UI hacks.
- Developed video calls using WebRTC—enabling users to call each other—which included developing protocol and requirements for the back end to implement a signaling server.
- Created several code-generation tools to simplify the use of string resources and the creation of new features using API endpoints.
- Built many prototypes as part of our "innovation" days, including a Bluetooth prototype that discovers nearby users even when the app is not running.
- Implemented a SwiftUI prototype to showcase a possible future architectural direction for the app.

CTO | Co-founder
2010 - 2013
Igobubble Ltd.
- Built a location-based app and back end that allowed virtual objects to be collected and dropped at physical locations; these so-called "bubbles" could contain videos and other media, and users could chat with any other users who touched a bubble.
- Developed a physics simulation in the main interface that showed bubbles bouncing around.
- Constructed a custom feed system and protocol to allow the app to receive real-time updates while connected.
Technologies: Objective-C, .NET, C#
Trainer
2010 - 2010
iOS Development Trainer
- Delivered several 12-day courses in developing iOS apps with a heavy focus on memory management and best practices.
- Created more than 15 exercises in which students created a small app to use a specific framework or technology.
- Spent the first three days of each course going over pointers, memory management, and the C language.
Technologies: C, Objective-C

Optiver
- Mentored several mid-level and junior developers in my team.
- Built, for my own initiative, a specialized remoting layer that makes distributed and multiprocessor server applications much easier to develop (a type of Tentacle framework).
- Held best practices presentation on writing multi-threaded apps in C# which included reviewing some common design patterns, dos and don’ts.
- Constructed a real-time server monitoring framework to make it easier to develop applications that can be centrally monitored (a type of Sentinel system).
- Developed several distributed server applications used by traders on the trading floor.
Technologies: C#, Microsoft SQL Server
.NET Consultant

- Revised a web service to serve the OLAP cubes for Data Miner (in VB.NET).
- Set up a continuous integration server using CruiseControl.NET.
- Introduced an Agile development process to the team and established comprehensive coding standards and best practices for VB.NET.

- Set up an automated test server to get-latest codebase and ran Selenium automated functional tests on several browsers, operating systems, and hardware, including macOS X.
Technologies: .NET, C#, ASP.NET
Software Engineer
2004 - 2006
Anite
- Worked as part of a team of over 20 developers on a $30-million n-tiered ASP.NET web application.
- Involved in most aspects of the software development lifecycle (SDLC), especially the design, UI prototyping, component implementation, and unit testing.
- Wrote a collection of utilities in C# .NET and ASP.NET to streamline software development processes within the team. These included tools for code generation and simplifying the installation of the Anite.
- Contributed to streamlining processes and procedures for the software team.

Experience
Megadoodle
An iOS social app that enables users to edit a giant pixel-based canvas with changes updated in real-time.
I developed this app for myself as a way to brush up on the latest advances in C++. It features a Git-inspired protocol for synchronizing pixel changes between devices robustly and efficiently. It also sends push notifications when someone draws near your work. Each pixel contains metadata about who drew it, as well as virtual layers of paint. Users can "scrape" layers of paint to reveal older pixels underneath.
