Freelancer profile translated to English.
Back to original languageAbout Enguerrand
Graduated in 2019 from EPITECH and Stockholm University, I have been a developer for about 15 years.
I have worked in various fields, with a particular appetite for backend and hybrid mobile development.
My journey has also included entrepreneurship; I created my first company in 2012 (Pulseheberg.com), I was the first employee of a startup that we led to an exit (Surprise.io - Sold to Skeepers) then managed the engineering of a blockchain leader in France (Lum Network). Then I supported Elmut (leader in pet food in France / Europe) in a complete restructuring of their technical stack, to give them the technological foundation to support their ambitions.
In my various experiences, I have had the opportunity to wear multiple hats and manage teams of various sizes, up to 10+ people.
I study each proposal to provide an informed and adapted quote to your needs.
