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.

Full Stack Developer
In charge of building/maintaining REST APIs using Node.js.(Hapi.JS, Angular.JS, Grunt, Unit Testing).
Prototyping the API using LokiJS (NoSQL document store) on a developer-driven (Android), agile and quick iterations workflow.
Switched then to a Mongo DB (NoSQl-document store) for a validation then a MVP release.
Continious iterations and refinement are mostly driven by market analysis and customer feedback.
Some of the skills I've brought on the project :
• IT Engineering : Scripting, task automation, task optimization, recommender system (Content based, content filtering => hybrid system).
• Security : HTTPS setup, crypto, log analysis
• Network : IPv6/IPv4 handling, Debian server setup/maintenance
• Database designing : MongoDB, LokiJS
• Development : NodeJS (v4, v6) HapiJS, Apache, AngularJS, Grunt, benchmarking, optimization
• Project : Creative/proactive force, strong entanglement with the team to answer the best to the needs of the product and the developer (Android/iOS).
I dedicated more than 1000 hours of work (on august, inc. week-ends and off-hours remote work) on the project. Trying to put the best of me to bring the best, reliable and secure product in the hand of the customer.
The global system need to answer to approx. 20.000 req/day.
• Front-end Jobs : Settings up multiple AngularJS projects (the biggest being the front-end of the socialNetwork) using Grunt then Webpack (<3), Bootstrap, Angular Material, projects are designed Mobile first (css3).
Used PHP and Apache's HTACCESS to trick facebook and twitter metaBot (og:tags, twitter:tags), in order to fix the unability of the twitter bot to run JS Meta Generation.
• Miscellaneous: Used GraphicsMagics (gm for node) to procedurally create unique share image specifically designed for Facebook, Twitter and Instagram. Data in these picture are loaded from the API and change many times per day.
• BI/Big data analysis in Mongo script (JS) from multiple collections.

Technologies used : JS, JQuery, DOM Modification : all original dom was destroyed and a new one was recreated using a path recursivity in order to display in form a dynamic tree + logotypes added by filetype. Dynamic download in order to be able to download either a full directory, some files or only a single file.
