Back to original languageAbout Lionel
Engineer by training, I honed my skills as a backend developer at Toluna, a startup that is now among the world leaders in online surveys.
I then developed expertise in cloud architecture (Amazon AWS, for which I was certified as a Solutions Architect) mainly in media (video) where I implemented a video-on-demand platform for the AB Group, highly scalable both for the backend (Symfony 3) and for content encoding (Python).
The AWS components implemented for this project were: EC2, ELB (auto scaling), RDS, ElastiCache, CloudFront, SQS.
As an entrepreneur, I recently created a startup dedicated to online bike rental that I developed entirely (Frontend Bootstrap + Backend Symfony 3 + iOS app + Android app), all based on a highly scalable architecture, also on AWS (EC2, ELB, CloudFront, RDS, ElastiCache, SNS, SQS, SES, ...)
I am capable of undertaking AWS Cloud architecture missions as well as Backend development.
