Raphaël Bellec
Verified Expert in Engineering
Code Architecture Developer
Raphaël is a jack of all trades, a master of Rails app development, a seasoned entrepreneur, and a developer with a demonstrated history of everything involving software engineering from scratch or hitting the ground running on existing projects. A few years ago, he decided to master RoR development because of its incredible idea-to-product speed. He’s also quite knowledgable about Python, Erlang, and Caml distributed apps, algorithms, and more.

The most amazing...
...thing that I've done was to create the first eTravel agency engine in Europe in 1996! It involved C, Erlang, kernel development, infrastructure, and much more!
Work Experience
Part-time CTO | Lead Developer | Developer
Freelance Work
- Worked for multiple clients, generally starting a project from scratch or helping to solve specific problems on an existing application.
- Developed two successful full-stack RoR apps, a native iOS application with an RoR back end, and a distributed process orchestration app in Python and ZeroMQ.
- Refactored several legacy code projects aiming towards a clean and thoroughly tested codebase and implemented best practices on moderns tools.
- Worked on various projects types and technologies.
- Acted as a part-time CTO to help recompose teams or set up new projects.
- Helped small business with simple and fast automation (Zapier and Integromat).
Co-founder | CTO
Structure Computation
- Created a commercial scientific computing framework to plug multiple numerical calculation tools and provide them with an on-demand business model.
- Managed a team of developers and researchers to create industrial products from research results.
- Oversaw the development of a synchronous collaborative 3D modelization tool in the browser.
Founder | CTO
Meet on Exhibitions
- 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.
CTO | R&D Manager
Netheos
- Architected, managed, and developed a USB device holding multiple network services with strong cryptography capacity and storage.
- Developed a full IMAP server and an SMTP that could be run on a pluggable device with specific crypto capacities.
- Built a full suite of services for nomad users with strong end-to-end cryptography.
- Set up and managed the software quality process.
CTO
Manobi
- Created a full MMS center operating on a 2.5G network in Sénégal.
- Developed and ran multiple high-availability services on a mobile network.
- Managed the development and operational teams based in three countries.
Founder | CTO | R&D
Travelprice.com
- Started Travelprice.com with three co-founders in 1996; in 2001, it became a leader in online tourism in Europe with more than 1 million of daily income and 350 people working in eight countries.
- Set up the first online travel agency engine that found all included prices of available flight in real-time on more than 400 carriers. It was all in C.
- Established a server farm before container and virtualization existed.
- Set up the first website with an online card payment system in 1996.
- Learned and experimented constantly for years on every relevant subject: logical, functional, and declarative paradigms, creating distributed service, low-level networks and systems, team building, and much more.
