About

With AI as an accelerator, I focus on what makes the difference: designing the right architecture, steering AI agents like a team, and keeping systems reliable from cloud to production. A full-stack tech lead, I'm moving towards DevOps and cloud architecture.

From healthcare to luxury and e-commerce, I've learned to adapt quickly to very different contexts and teams, in French and in English. I enjoy sharing knowledge, making complex things simple, and helping the developers around me grow.

Experience

Full-Stack JavaScript / TypeScript Developer · SQLI

Dec 2024 — Present

Lausanne, Switzerland

As technical lead on the MySWSIR project for Cardis, I ensure the continuity of the work undertaken, mentor two junior developers, and design technical solutions to meet client needs. The stack relies on TypeScript, React, CDKTF (Infrastructure as Code) and AWS, with OData for querying the Microsoft Dynamics CRM.

  • MySWSIR. Migrate the features of the Immomig tool to a Microsoft Dynamics + custom-development solution, allowing Cardis to verticalize the solution for its various partners and affiliates.

  • AWS infrastructure. Design and maintenance of the project's AWS infrastructure as code with CDKTF (Terraform CDK).

Strasbourg, France

SFEIR is a neo-ESN regrouping 600 developers specialized in web applications and cloud computing. SFEIR has agencies in Paris, Strasbourg, Nantes, Bordeaux, Lille and Luxembourg.

  • LVMH Clienteling Platform. Development of the Clienteling Platform for LVMH. This platform allows client advisors to communicate easily with their clients, register new clients, handle their tasks, see their KPIs... The platform's architecture is a set of microservices deployed in GCP and developed with NestJS. Client data is queried from Salesforce. The infrastructure runs on Kubernetes (GKE) on GCP and is deployed following a GitOps workflow with FluxCD.

  • Development of a web application to manage your budget called BGV (Budget Grande Vitesse) for CRESUS (an association helping persons in debt). Users can sign up and aggregate their banking accounts to help them classify and create their budgets. This application is developed in Angular and deployed on Google Cloud Platform.

CONDOR Project · IHU Strasbourg / IRCAD

Mar 2017 — Aug 2020

Strasbourg, France

The aim of the CONDOR project is to develop new computer technology systems to significantly help surgical teams avoid human errors in the operating room.

The project includes collaborations with academic institutions and leading industrial companies, and proposes a range of major technical innovations: the first open DICOM standard for surgical video storage and transmission, low-latency video data transmission, surgical ontologies, pre-operative and real-time intra-operative medical data visualization, and AI systems for surgical video analysis.

CONDOR is also inspired by the aviation industry, imagining a "control tower" and a "black box" that monitor and record everything happening inside an operating room during a surgical procedure.

  • Development of a microservices architecture system based on web technologies to record and supervise data from operating rooms.

  • Project coordination (project & team management, demonstrations, presentations, article writing).

Junior consultant · Altran

Nov 2016 — Feb 2017

Strasbourg, France

Altran is a global leader in Engineering and R&D services. I worked as a junior consultant for the IRCAD IT team and for the Altran R&D service.

  • IRCAD IT department. Using the AngularJS framework, the goal was to create a web application that lets the IT team easily create LDAP, entry-pass access and NetApp configuration for new users. I also developed the web API to communicate with the LDAP server using Python.

  • Altran R&D project. Development of a PaaS (Platform as a Service) application to compute scientific algorithms on medical images. Users send their algorithm files and medical images through a web interface; the data is then computed in Docker containers and the results are displayed on the interface.

Internship: Final project assignment · IRCAD

Feb 2016 — Jul 2016

Strasbourg, France

The goal of this assignment was to bring the FW4SPL framework (renamed SIGHT) to the web. To do that I used Emscripten, a compilation toolchain that compiles C++/C into JavaScript. I managed to compile a client-side medical-image anonymization tool using the DCMTK library compiled to JavaScript.

  • Use the Emscripten toolkit to compile FW4SPL dependencies (DCMTK, VTK, ITK, Boost...).

  • Use the Emscripten toolkit to compile FW4SPL libraries.

  • Compile a DICOM anonymization application into JavaScript (using Emscripten) for client-side anonymization.

  • Project presentation and report writing.

Internship: Engineer assistant · IRCAD

Sep 2014 — Feb 2015

Strasbourg, France

The goal of this assignment was to develop a web viewing tool for medical data. This tool displays DICOM images (medical images) and 3D models of organs and lets the user interact with them.

  • Conduct a state of the art of WebGL frameworks.

  • Development of a web viewer for DICOM images and 3D organ models.

  • Project presentation and report writing.
