Co-founder | CTO2010 - 2014Structure Computation

- Oversaw the development of a synchronous collaborative 3D modelization tool in the browser.
Founder | CTO2010 - 2013Meet on Exhibitions
Technologies: Ruby on Rails (RoR), Ruby, Android, iOS
- Created and developed an application engine: the goal was to provide off-the-shelf applications for specific needs of events (concerts, exhibitions, festivals, and the like). These apps' engines were written in native iOS and Android, they then played an application description in a domain-specific language. Apps could be updated remotely thus avoiding the need to go through a validation procedure in application stores. Exhibitions managers could update all their information (schedule, maps, exhibitor list, and so on) on a web service (Ruby on Rails). Applications were then automatically updated when they were notified (automatic update was not provided by Apple/Google) and the apps could work without network during the event (frequent constraint).
- Set up a continuous deployment pipeline with 100% code coverage. This was the first time I decided to try the "no compromise on quality metrics" and validate its interest.
- Created and managed the full sales process.
