A highly automated, data-driven financial audit platform that was part of KPMG's global efforts to innovate financial audits for both large and small clients. My team in the Nordics focused mainly on small clients with a higher degree of standardization due to the larger legislative pressure on small audits.

A fully autonomous drone platform for indoor security, data collection, and other uses. We created our own positioning, navigation, flight stabilization, and data streaming system, as well as a web application for scheduling and optional manual flight control.

G-cluster: Cloud Gaming Platform
A cloud gaming platform where video games, ranging from solitaire to the newest AAA releases, are played entirely in the cloud on a subscription basis. The game videos are streamed to players, and their button inputs are streamed back. You can literally pause the game on your TV, go outside, unpause it on your phone, and continue. No gaming hardware is required even for the most graphically advanced games. One of my tasks was to repurpose source code from computer games for the cloud platform.
