Freelancer profile translated to English.
Back to original languageAbout Jonathan
Curious and fascinated by new technologies, I obtained a Master's degree in Digital Business before working for 2 years as a project manager in a web agency in Paris.
In 2018, I completed a web development training course (Le Wagon). I then worked as a backend developer in a Parisian startup for over 3 years. Gradually, I improved my frontend skills, which allowed me to be completely autonomous in feature development.
At the end of 2021, I left OFF-WORKS to join Alyra's training program to specialize in Blockchain development. During this 3-month training, I was able to develop several dApps using technologies such as: Solidity, Truffle, Web3.js, React. IPFS...
I am available to work on web and Blockchain development projects starting in September.
My priority is to perfectly respect the requirements of the functional specifications as well as the associated planning.
