About Stéphane

Software engineer since 2008, I support your technological projects by leveraging my experience.
I started my career as a developer, researcher, and architect for a startup working on the principle of augmented reality.
I then developed a taste for entrepreneurship and intrapreneurship in my subsequent experiences.
I continued at Dassault Systèmes from 2010 onwards on their CATIA software. My role was to add and improve functionalities as well as integrate external products following acquisitions.
Subsequently, I went to Canada at Nuance Communication in 2013 with the desire to discover a new way of working. This is how I was able to perfect my skills by working with talented teammates. The concepts of Agility, SOLID, and TDD held no more secrets for me!
Upon my return to France, I co-founded TAYO, the startup that facilitates the travel of professionals going to their events by offering connections between users and routing algorithms.
Since 2017, I have been a freelancer and I put my experience to the benefit of my clients.

My vision is:
- That IT serves businesses, and not the other way around.
- That the developer must be an architect and must understand the client's needs.
- That the developer is responsible for the quality of the final product

Finally, I consider myself a software "craftsman"; I like to produce quality code to reduce maintenance costs while maximizing the time spent developing features.

Looking forward to meeting you

Experience

  • Prismea
    Technical Lead
    BANKING AND INSURANCE
    November 2019 - August 2021 (1 year and 10 months)
    Lyon, France
    Prismea is a banking agent for professionals created in 2018, with development starting in late 2019. Prismea offers a dematerialized banking experience with the support of FinTech (like Treezor or October).

    I joined in the early months of the project, starting with a developer/architect role to define the overall platform architecture and the software architecture of each micro-service. Given Prismea's constraints, we opted for a Hexagonal architecture with the Domain built using a DDD approach (without being overly strict), all in Continuous Deployment (up to production).

    I took on a Manager role to help the team grow from 3 to 26 people. It was necessary to regularly rethink the team's organization towards Feature Teams. The approach of development through TDD and task Groomings allowed us to maintain high and consistent quality and to retain strong engagement.

  • Sogelink
    Expert Developer
    CIVIL ENGINEERING
    December 2018 - March 2019 (4 months)
    Caluire-et-Cuire, France
    Sogelink is the leader in SAAS solutions for construction sites and networks.
    I joined the Bolt team, which is responsible for the company's internal tools and communication with the State for the declaration of works and incidents.

    Initially, I worked on the new communication formats required by the State for companies. The objective of this development was to ensure that the application teams had no impact despite significant functional changes. Then, I implemented OAuth 2.0 by configuring the existing CAS (Central Authentication Service).

  • Apave
    Technical Expert / Tech Lead
    AVIATION AND AEROSPACE
    March 2018 - October 2019 (1 year and 7 months)
    Lyon, France
    Apave is one of the leaders in technical, human, and environmental risk management. Apave offers training, audit, and IoT solutions to its clients.

    The Apave technical platform is a technological hub where all company software can connect to communicate with each other.

    In this context, I developed the frontend of the administration portal and then the backend to integrate critical functionalities, improve the performance of the API gateway (response time < 1ms), and the robustness of the product (resists service crashes, daily reliability rate of 99.9999%).
    To improve team velocity and accelerate deliveries, I implemented a continuous integration platform. Finally, I worked on the documentation of tasks and delivery cycles in a Waterfall ecosystem but with a desire to migrate to Agile.
