Hi, I'm Julien

Clinical Orthotist · MedTech & Connected Medical Devices
Bridging clinical practice, product, and embedded systems

I am a state-qualified orthotist with four years of clinical experience in France and Canada, followed by a second path into software engineering, Linux systems, edge computing, electronics, and embedded technologies.

I work where both worlds meet:

the human body, physical devices, software, and real-world deployment.

Development activity notice
Since January 2026, my active development work has been hosted primarily on my self-managed Gitea instance: git.enuxia.fr.
This GitHub profile remains available for selected public projects, historical repositories, and professional visibility.


What I bring

Clinical and field experience

  • Four years working directly with patients
  • Biomechanical assessment and functional analysis
  • Design, fabrication, fitting, and adjustment of custom orthoses
  • Collaboration with physicians, surgeons, and physiotherapists
  • Practical understanding of morphology, comfort, materials, and real-world device use

Systems and software engineering

  • Rust systems and backend development
  • Linux and edge infrastructure
  • Communication with physical devices
  • Embedded and IoT experimentation
  • Secure local and on-premise deployments
  • Production-oriented system integration

A bridge between both worlds

I can understand a clinical need, discuss it with healthcare professionals, translate it into product or technical requirements, and collaborate with software, hardware, product, and engineering teams.


Current direction

I am focusing my career on technologies that improve mobility, rehabilitation, autonomy, and clinical practice.

Areas of particular interest include:

  • Digital orthotics and assistive technologies
  • Connected and instrumented medical devices
  • Clinical applications and product development
  • Embedded systems for healthcare
  • Edge computing and local healthcare infrastructure
  • Device integration and interoperability
  • User testing and field deployment
  • Technical and clinical support

I am open to opportunities in France and across Europe.


Enuxia Health

I co-founded Enuxia, a technology project progressively specializing in healthcare systems.

Our direction is to design, integrate, secure, and maintain systems connecting:

  • software and healthcare data;
  • local and edge infrastructure;
  • physical equipment;
  • sensors and embedded systems;
  • healthcare professionals and real-world workflows.

The long-term ambition is to contribute to non-invasive assistive technologies, clinical instrumentation, active orthoses, and human functional augmentation.

Enuxia is being developed progressively, with a strong focus on useful, maintainable, secure, and field-ready systems.


Selected work and repositories

Most of my recent development activity is hosted on my self-managed Gitea instance:

Since January 2026, I have used it as my primary environment for:

  • active software development;
  • private and internal repositories;
  • infrastructure-as-code;
  • Docker and deployment configurations;
  • CI/CD workflows;
  • embedded and edge projects;
  • technical documentation.

GitHub remains my public-facing profile for selected repositories and professional visibility.


Selected projects

Production Rust system

Designed and deployed a production system using:

  • Rust
  • Axum
  • WebSocket communication
  • Physical access-control readers
  • Real-time decision logic

The system is actively used by an institutional client and connects backend software with equipment deployed in the field.

Healthcare and edge infrastructure

Work and experimentation around:

  • Linux-based local systems
  • Docker and service orchestration
  • Secure networking and VPNs
  • Monitoring and remote maintenance
  • Raspberry Pi and edge nodes
  • Offline and locally controlled architectures
  • Healthcare-oriented self-hosted services

Embedded and physical systems

Projects involving:

  • communication between software and physical devices;
  • Raspberry Pi and microcontroller-based systems;
  • sensors, GPIO, and device protocols;
  • firmware experimentation;
  • hardware integration;
  • field deployment and diagnostics.

Digital health education

I teach digital health topics to Bachelor's and Master's students, including:

  • connected medical devices;
  • health data sovereignty;
  • cloud versus edge computing;
  • cybersecurity in healthcare;
  • artificial intelligence in healthcare;
  • healthcare interoperability;
  • regulatory considerations.

Hands-on hardware

Personal projects involving:

  • electronic soldering;
  • component selection;
  • hardware assembly;
  • firmware configuration;
  • Raspberry Pi systems;
  • FPV drone design and construction.

Technologies

Systems and software

Rust C Python Linux Axum Tokio

Communication and integration

WebSocket MQTT REST APIs GPIO Device Integration

Edge and infrastructure

Docker Proxmox Traefik VPN Git Raspberry Pi

Embedded and hardware

Embedded Linux Microcontrollers Sensors Electronics IoT

Healthcare

Digital Health Medical Devices Orthotics Biomechanics
HL7 / FHIR concepts DICOM concepts Health Data Protection


What I am looking for

I am particularly interested in roles such as:

  • Clinical Application Specialist
  • Medical Device Product Specialist
  • Field Application Specialist
  • Clinical or Technical Support Specialist
  • Digital Orthotics Project Manager
  • Embedded or Systems Engineer in MedTech
  • Product and user-testing roles for assistive technologies
  • Healthcare technology deployment and integration roles

My goal is not to choose between healthcare and technology.

It is to work on products and systems where both are necessary.
