About Nicolas

Hello and welcome to my Malt profile, I am a blockchain & back-end developer on a work-study program at Futurs.io, — a Blockchain innovation firm of the Maltem Consulting group and recognized by Gartner — and I am pursuing a Master's degree in Software Architecture at ETNA. I am also a freelance developer, passionate about use-cases related to blockchain technology, and more particularly through Ethereum!

I work at Blockchain-Studio and Futurs.io, two ambitious startups within the Maltem ecosystem through the Rockside and PurChain blockchain solutions, a Wallet dedicated to businesses and a food traceability solution, both operating via Ethereum.

My skills are mainly focused on back-end development (Golang, Node.js) and Cloud infrastructure (Microsoft Azure, Google Cloud), where I actively participated in the production deployments of our applications (permissioned Ethereum nodes, front & back, managed databases, HashiCorp Vault & Consul) via Kubernetes/Docker and Gitlab CI.

I also completed a 6-month internship at PayGreen, a French online payment solution, where I worked on the main technologies related to the e-commerce world (development of payment modules for WooCommerce, Prestashop, and Salesforce Commerce Cloud). I also had the opportunity to implement the Tree carbon offsetting algorithm and update their banking mailing system.
