Working on the backend for Fortnite.

Seattle, WA, US

• Launched Amazon GameSparks, a new AWS service allowing game developers to build a serverless backend for their game.
• Designed and built several service components and oversaw the design of many more.
• Led design and implementation of its Game SDK implemented in C++, used to integrate game clients with the backend using a persistent bidirectional connection.
• Game SDK game client integrations possible from a low level C API, all the way up to an integration into the Unity game engine. Emphasis on low CPU and memory overhead at runtime.
• Built runtime Game SDK support for desktop and mobile platforms and designed and built a build pipeline to build and test the Game SDK on all supported platforms.
• Worked on several maintenance, security, and migration projects for the legacy GameSparks service acquired by AWS in 2017.

Seattle, WA, US

• Built SDKs for integrating game clients with a collection of game backend services used internally at Amazon Game Studios. SDKs included:
• A client library for submitting events to a data analytics pipeline service in a lock-free and wait-free manner.
• A client library for a notification system that eliminates polling by using a persistent bidirectional connection with the server.

Amsterdam, NL

• Lead developer for company’s main C#/.NET-based proprietary trading front end GUI software, aggregating large scale, real-time trading data from various sources to be visualized intuitively.
• Initiated and developed a daily regenerating test environment to facilitate integration testing of new or updated components.
• Developed a scripting framework to allow traders to automate common and error prone manual actions. Automation risk is reduced by providing a sandboxed testing mode.
• Focus on clean code, using test driven development and agile methodologies.
• Actively involved in recruiting and interviewing process.
• Designed, implemented, and tested TCP and UDP networking components in C++ for Linux systems. Focus on low latency and high runtime performance.

Davis, California, US

Designed and implemented a system used to interactively visualize ultra-scale volume data on commodity hardware, using an image based intermediate representation of the data. The system facilitates the creation of video of the original, full-scale data, directly guided by the user.

Designed and developed dynamic, database-driven websites, and business software for small businesses in C#/.NET and C++/MFC.

Toronto, Ontario, CA

Implemented a system capable of reconstructing 3D shapes from photos. The system takes a series of photos taken of a target object of unknown shape, under different lighting conditions, along with a series of photos of a reference object, of known shape, under corresponding lighting conditions, and uses this information to reconstruct the surface of the.

Member of a team of students developing a train simulator used in the training of train drivers by the Dutch national railway company. The work was performed according to the ESA software engineering standard. My responsibilities mainly involved the development of the 3D graphics engine used in the system.
