My name is Yann, a computer engineer and doctor in sports science (STAPS). Thanks to my multidisciplinary background, I have developed several innovative mobile applications (iOS and Android), websites, and software integrating external sensors and interactive interfaces.

Some notable achievements:

• ✂️ AYEDN: Mobile application connecting clients with hairdressers/barbers, featuring profile management, recommendation algorithm, and geolocation for a personalized experience.

• 🏋️ TRAINIMM: Sports tracking application for a sports science lab, integrating Strava, Garmin, and Suunto APIs to retrieve training data. Available in 3 languages, it facilitates field scientific studies.

• 🎥 MOVINLAB: Platform for creating physical activity programs including exercise videos to guide users.

• 🔬 Website for a scientific study on MS: Web application to supervise a scientific study with a drag & drop system for sending activity plans directly to the subjects' mobile application.

🔎 Available for your mobile and web application projects, I am known for my proactive approach, my rigor, and my passion for developing quality digital solutions.

FANTASI SMART - 2D Game Software for Children with Pathologies
PUBLIC SECTOR
September 2024 - December 2024 (3 months)
Saint-Étienne, France
An interactive software developed in Python for Windows, combining gaming and scientific evaluation to make muscle tests more accessible and motivating, especially for children with SMA (Spinal Muscular Atrophy) and SCI (Spinal Cord Injury).

2D Game with Avatar Selection: Users choose their avatar and perform playful actions like eating objects (bones, bananas, etc.) to represent muscle contractions. The game is designed to make strength tests more engaging.
QIF test (quadriceps-intermittent-fatigue): The software offers an incremental test where users must contract their muscles at different intensity levels (10%, 20%, 30%, etc.). Each strength level is represented by a specific action in the game.

Two distinct interfaces:
Player Interface: Main view with the 2D game, fun and immersive.
Experimenter Interface: Management mode with:
A MVC (Maximum Voluntary Contraction) mode to calibrate strength levels.
Demo and game modes to supervise sessions.
A dashboard displaying parameters and test progress in real-time.

User Management: Experimenters can add and manage participant profiles, with local data backup in an SQLite3 database.
Scientific Study: This software is specifically designed for a study on the evaluation of muscle strength in children with SMA (Spinal Muscular Atrophy) and SCI (Spinal Cord Injury).

This project illustrates the successful integration of technology and gamification to meet specific scientific and medical needs.

A fun and scientific software, designed to evaluate muscle strength in children through an interactive game, transforming clinical tests into engaging experiences.

AYEDN
Full-Stack Mobile App Developer | AYEDN for Barbers
HEALTH AND WELLNESS
June 2024 - Today (2 years)
Saint-Étienne, France
I developed AYEDN, a revolutionary mobile application dedicated to the world of barbers and discerning clients looking to find a professional that matches their style. AYEDN features a dual interface: one for individuals looking for a barber and one for professionals managing their business.

For clients, AYEDN offers a personalized recommendation system based on geolocation and preferences, as well as precise filters (skills, prices, availability, etc.). Users can view barber profiles, check reviews, and book appointments directly.

For barbers, AYEDN is a comprehensive management tool allowing them to track their schedule in real-time, organize their time, manage their services, and increase their visibility through a richly detailed profile.

I led the project from start to finish, handling front-end (React Native) and back-end (Flask, Python) development, as well as configuring a MySQL database. I also managed the repositories on the Apple and Google Play platforms.

EVALIFE MOBILE STATION
PUBLIC SECTOR
October 2023 - February 2024 (5 months)
Saint-Étienne, France
An innovative station designed in collaboration with the RDI design office (Laurent Terrat), combining advanced hardware and software solutions to provide precise assessment of physical capabilities.

Comprehensive Assessment:
Upper body strength: Test performed with a 3D-printed handgrip, specifically developed for this project.
Flexibility: Measured using a linear encoder for optimal accuracy.
Balance: A dedicated test to analyze postural stability.

Dedicated Software: Each tool has its own software developed in Python and controlled via an intuitive graphical interface designed with AngularJS. Communications between the tools and the server are handled by WebSocket for real-time synchronization.

Optimized User Experience:
Touchscreens integrated into each tool, with video instructions to guide the user through the tests.
Quick and simplified registration thanks to a central server controlled via Node.js and a MySQL database.
A central screen aggregates and updates the results of each test in real-time, providing an immediate overview.

Embedded Hardware: Each tool is equipped with a Raspberry Pi for independent management, while being connected to the overall system.
This connected mobile station is a significant advancement in the assessment of physical qualities, combining technological innovation and ergonomics to meet user needs.
