Alex in a few words

Ancien lead technique de Dash (ayant participé à la création de valeur ayant permis la croissance de la capitalisation de 78M$ à 10B$).

J'ai une expérience assez forte dans le secteur de la tokenization, la mise en place de blockchain applicative ou la réalisation de smart-contracts, incluant la compréhension légale et réglementaire.

De manière générale, j'accompagne les porteurs de projet à la réalisation "clé en main" de leurs produit (front-end, back-end, infrastructure) et suis donc capable de venir aider à chaque étape de la réalisation de votre projet et sur une grande partie des silos technique de votre projet.

I've decided to dedicate all my abilities in order to do a meaningful things : Offering a solution to every people to flee from this banking system slavery/craziness.

Working remotely with one of the best team out there, trying to improve our already existing crypto-currency.
Dash is one of the top coin out there (3rd behind Bitcoin and Litecoin to have it's focus headed toward currency).
We're improved the process of Dash integrating instant transaction (~1s) and private transaction (anon) in order to offer a way to user to use a cash that is really in their possessions and not in the banking system one.

My work here is to handle the Backend part, our particular system allow us to propose new feature for users using more than 4400 Masternodes.
Making Dash able to bring the first totally decentralized service focusing on UserExperience, in order to fix the complexity of crypto-currency for un-tech people without doing any trade of in security nor anonymate.

We are here helping you to be independant, to be your own bank, to be free from anyone decision to print huge amont of paper-money, to be free from Central Bank, Local Bank.
Dash, it's digital cash.
