Alexandre in a few words


I am a passionate full stack developer. My areas of expertise are Angular (but also solid notions of React JS, his competitor), Firebase (hosting, function, authentification, rules), crypto-payment (Solana and Ethereum), and 3D running inside the browser.

I am an authentic start-up guy and I am excellent at producing proof-of-concepts for investors, and analysing technical trends.

I love to advise my clients : I want them and their to have the maximum chances of success, to be lindy.
