JaccedeFebruary 2015 - Present

I began with an outdated platform with lot of instability. After few month I decided to do everything from scratch. I had to write a new API, as simple as possible, and a website using it. I did the servers migration on AWS with lot of customization. The longest part was to migrate the data which was inconsistent to have beautiful database with well-formed data. When a user can enter an adresse without restriction or user can have multiple account with same email, I let you imagine what you get.. It's just a part of the iceberg but it was a good challenge to identify duplicates and other specials case.

My daily work is:

- Manage and develop new features for API developed with Flask.
- Manage and develop new features for new website in full AngularJS
- Write API documentation
- DevOps: linux, nginx, apache, Amazon web services, fabric, ELK (elasticsearch logstash and kibana), prerender.io
