Senior Scientist
BAE Systems

Software Developer
Medical Research Council
- Developed a web server that provides sectioned visualization of extremely high-resolution 3D models as a tiled service—Google Maps but the data is 3D scans. This web service has been running for 12 years on the Edinburgh Mouse Atlas website.
- Designed the UI and software architecture, and then coded software in C++ and Qt to warp 3D objects as a volume and not just their surface.
- Ran image processing algorithms on an 8-node-cluster.
Project History
QuestNative Mobile App
http://www.questnative.comDigital Blue Badge App
I have provided functional requirements and helped a designer come up with v1.00 of the prototype showed in the link. Then, based on this prototype, I have developed the v2.00 of the app front end in React Native to match the initial mock-up that was released via Bitrise to iOS and Android app stores. The UX is currently being tested.
