Unity Game Development

Having learnt coding in C# and using Unity3D in my free time, I worked on a multi-platform infinite runner / side-scrolling game.

Senior Back End Engineer at Codiscope

Codiscope's mission is to improve the quality of software everywhere by creating tools that work throughout the entire software life cycle, rather than only during test phases.

What I did:

• Prototyped and wrote the first version of the static code analysis tool for the Javascript language

• Implemented OAuth user signups using GitHub and BitBucket accounts
