My projects

Wave

Tech Lead - Scrum Master - UX/UI Designer

Veolia Recyclage et Valorisation des Déchets, Aubervilliers

Wave is an Android application, used by drivers who collect waste, to dematerialize the reporting of their work. The operation center has a real-time view of the situation.

In an agile DevOps team of 10 persons, I initiated and carried out the transition from Scrum to Kanban and from Java to Kotlin, the use of Continuous Delivery and Test Driven Development, and an UX/UI redesign.

Edgar

Tech Lead - Scrum Master - Product Owner - UX/UI Designer

LafargeHolcim, Clamart

LafargeHolcim innovates in concrete by offering products with special properties. Although these products are more expensive than common concrete, benefits are there: less labor, less working time… Salesmen have to convince their clients of the benefits. This is the purpose of Edgar, an Android application, that compares the global cost of the different products with information regarding the work to do (surface, labor cost…).

I developed the Android mobile application and the backend. I set up an agile workflow to work with the concrete business unit. Directly connected to the business, I was responsible for Product Backlog management.

Received Recommendations

Bertrand Dienis

Associate at Excilys

Apr 6, 2020 - Manager

J’ai eu le plaisir d’être le manager de Nicolas pendant 5 ans et je regrette déjà son départ de chez EXCILYS.

En 5 ans, j’ai vu Nicolas évoluer et progresser rapidement de responsabilités de développeur expérimenté à Tech Lead confirmé.

Au sein des équipes projet qu’il a eu à encadrer, Nicolas a assis sa légitimité sur son expertise technique, mais également sur des compétences et aptitudes qui dépassent largement le cadre technique :

  • Sa curiosité naturelle et ses capacités de reformulation en font un interlocuteur de choix pour comprendre et challenger les besoins utilisateurs, mais aussi pour présenter simplement les choix techniques ;
  • Son leadership lui permet d’animer et d’impliquer son équipe, tout en lui transmettant sa sérénité ; Nicolas est une personne calme et posée, y compris en périodes de stress ;
  • Nicolas est un bon communicant, tant à l’oral qu’à l’écrit, et a démontré sa capacité à s’adapter à de multiples contextes et à de multiples intervenants à travers les missions qu’il a eu à gérer.

Avec près de 10 ans d’expérience désormais, Nicolas est indéniablement prêt à s’attaquer à de nouveaux challenges, en tant que Directeur de projets, de Product Manager ou même de Directeur Technique d’une petite entité.

Ce fut un véritable plaisir de travailler avec Nicolas, tant sur le coté humain que technique.

J’ai particulièrement apprécié son professionnalisme et son implication dans la mise en oeuvre d’une cellule Agile DevOps sur des applications métier au sein de Veolia.

Cette implication nous a permis, en plus de l’aspect techlead, de profiter de son expertise UX/UI et Scrum Master.

Apr 2, 2020 - Manager

Nicolas a été un élément essentiel de notre équipe DevOps pendant presque 3 ans où il a su apporter de l’innovation tant au niveau développement qu’au niveau organisationnel.

En plus de sa maîtrise technique, je ne peux que recommander son sens du produit, sa recherche constante d’amélioration et sa maîtrise des concepts agile.

J’ai eu le plaisir de travailler avec Nicolas pendant une année dans l’entreprise Veolia. La capacité de Nicolas à jongler avec plusieurs projets est unique et fait une énorme différence dans le niveau de notre équipe et sa productivité. Nicolas est un atout pour n’importe quelle équipe !
