I am a Research Software Engineer at Microsoft Research in Cambridge, UK. I finished my PhD at Imperial College London, where I worked with Dr. Alastair Donaldson on scalable techniques for analysing and testing real-world asynchronous software systems. For my PhD thesis, I created P#, an asynchronous programming framework that comes with built-in static analysis and controlled testing capabilities, which is now used by engineers in Microsoft to design, implement and thoroughly test distributed systems and services for Azure.
I am currently working (or have previously worked) on the following projects (not up-to-date/complete):
- [git] P#, a framework that simplifies developing, analysing and testing asynchronous programs, such as web services and distributed systems.
- Designed and implemented a new, more efficient, client-based formula evaluation runtime (written in TypeScript) for Excel Online.
- Dungeon Story, a Puzzle/RPG game that I developed (as a hobby project) during summer 2012. The game is available worldwide in the iOS App Store, it has been downloaded by more than 195,000 users, and has hundreds of 4.5/5 star ratings.
