About Alexis

30 years of coding, structuring, and leading software projectsfor various organizations (startups, software vendors, large corporations).

My favorite roles are those where I have aLead Developerposition, working with open-minded and curious colleagues. My preferred environment is one where we find the right way to develop. Not the fastest way, nor one where we build fanciful things, but one where we find harmony within the team, with the client, and in what we produce. A place where we can look at our code without shame several months later. A place sometimes referred to as software craftsmanship or software artistry.

I am looking for a mission for a few weeks or months,

Experience

    SPORTS
    September 2024 - October 2025 (1 year and 1 month)
    In 2023, I created a prototype that retrieved sports activity data from Strava and formatted it in a personalized way.

    This project is the cleanup of the prototype to make it a real self-hosted application.
    The ambitions are greater in formatting data for sports clubs.

    TECH
    September 2022 - August 2024 (2 years)
    For this project, the team is entirely international, with a client based in the United States and developers spread across India, Pakistan, Western Europe, and North Africa. Most importantly, the team consists of inexperienced developers with a low technical culture.
    As a lead developer, my role is to guide the team in the right direction. Given the significant functional complexity and strict quality constraints, it's essential to instill ambition in the team members.
    Furthermore, I personally developed a considerable number of technical components, particularly in the area of ACLs, which involve complex rules and a significant performance challenge, as well as the central AMQP broker in the architecture.

  • Acoem
    Full-stack development
    INTERNET OF THINGS (IOT)
    February 2022 - July 2022 (5 months)
    After a successful initial phase in 2021, the project moved to a new stage with the integration of new devices specialized in sound detection (firearms, vehicles). These new devices required modifications to the communication protocol, as well as to the displays and management rules.
    Although the team has changed somewhat, the rigor has remained the same regarding the agile approach, code quality, and deliverables.
