Digital Portfolio presentation tool to visualize and manage digital transformation

  • Project Management
  • Web
  • 3D UI

The Digital team have to manage an extensive project portfolio. They follow each digital initiative in the company worldwide. Each quarter, they produce an internal report to show an overview of the digital transformation progress.

This tool simplifies portfolio management and delivers a modern UI for presenting results to executives.

Le Temps des Glucides

Mobile app for ingested sugar tracking and diet management

  • Healthcare
  • Mobile
  • iOS
  • Android

This project came from parents of a diabetic child who adapted a powerful method to easily calculate how much sugar was contained in any meal, snack or drink.

The app (now retired) featured several ways to add sugar (weight, portion, favorites...), an advanced version was made that calculated how much insulin needed to be injected (but not released due to costly certifications).

I developed and released both Android and iOS versions using the Titanium SDK.

Collaborating with the client, I understood and implemented their carbohydrate‑calculation method.
I developed the iOS and Android version in nodeJS-like JavaScript, and deployed the app on both stores.
The app got covered in several press releases and earn recognition in local entrepreneurs festivals.

Serious Game about industrial operation AI-powered transformation

  • Project Management
  • Game Design
  • UI
  • Game Dev

This game was created for Vivatech Paris tech fair. The goal was to introduce visitors to industry and how AI allowed for enhanced operation.

The game was developed in Unity, I proposed the concept and was in charge of the game design, I was also involved in supervising the development.

The game was later converted to an internal training course for newcomers, ported from iPad to WebGL, and translated into 10 languages.

A few years later, I worked on another similar serious game, focusing on teaching the basic principles of gas cylinder logistics.

Play the game
In 2018, one month before the Paris Vivatech tech fair, I pitched the idea of a resource management game to highlight Air Liquide innovation in operations. I designed the game storytelling and mechanics and managed the development team.
The game switches from tutorial/storytelling and gameplay phases. The tutorials introduce the player to new mechanics and changes in the level.
As the player progresses, the game becomes more complex, with more customers to deliver, more production to manage and occasional equipment breakdowns.
I conducted playtests to make sure the game was balanced, and during the tech fair, I adjusted the difficulty to the ability of real visitors.
A few months later, I updated the design to convert it to WebGL as an internal training course for new recruits. I re-wrote most texts to align them better with the company's vocabulary and I managed the development team and synchronized with translation teams to provide text in 10 new languages.
A few years later, I was asked to design a new game to explain gas cylinders' logistics. This new game re-used some assets of the first one, but most assets were unique.
At the end of each level, the player is given a detailed score and rewards.
An internal competition was conducted between employees to decide who was the best virtual plant manager!

Hachette Livre / Éditions Foucher

Educational quizz mobile app for medical students

  • Education
  • Mobile
  • iOS
  • Android
  • Gamification

The objective of this project was to convert all Éditions Foucher study books to a quizz app.

The app (now retired) used original XML files from the books, removing the need for manual conversion.

The app allowed some free quizz and used in-app purchase to acquire more content.

The biggest challenge was to integrate all the various Q&A layouts, since they were composed of text and many images.

I developed the app in JavaScript using the Appcelerator Titanium.
This allowed to create and manipulate native UI elements for iOS and Android, and get much better performance than other frameworks.
The features a training mode and an exam mode, following the original books structure.
I developed a parser that takes original books XML files and convert them into quizzes. This allowed to integrate hundreds of questions easily using solid material.
One difficulty I encountered was integrating XML quizzes with no existing documentation.
Questions and answers could integrate images and mathematical formulas.
The student scores are tracked by the app to measure their progression.

Air Liquide Healthcare

eCommerce portal for medical gases and equipment purchases in Europe

  • Healthcare
  • eCommerce
  • User Research
  • Design System
  • Web Design

For this project, I conducted 20 interviews across 3 countries and designed the portal's UX.

Working closely with marketing and digital teams, I made sure we improve user adoption and customer acquisition while respecting local legislation (it is not allowed to advertise the qualities of medicine products in Europe).

It allowed hundreds of customer to switch from phone/fax ordering to purely digital.

This project also paved the way to Air Liquide's Design System.

I conducted interviews and user tests at different doctor offices and clinics in France. With help of local partners, we also conducted remote user tests in Spain and Portugal.
This helped us understand current user's habits and expectations before switching to digital ordering.
Air Liquide Healthcare proposes many different products, so I proposed a first screen that would filter products by medical specialty.
This first choice also impacts the editorial content that is displayed on the home page.
The home page features quick access to products and content relevant to the chose specialty.
The product page required a lot of iteration with the legal team. In Europe, advertising medical drugs is forbidden, and the definition of advertising is very large in legal terms.
For this project, I was not able to follow the development phase. I documented each UI component precisely in an integration guide.
Those guidelines were later used to build the Air Liquide's Design System.

Air Liquide Benelux

Augmented Reality tool to collect data and simulate on-site equipment installation

  • Mobile
  • Augmented Reality
  • Prototyping
  • iOS
  • Unity

As an AR/VR internal expert, I was contacted to design and prototype an AR app to experiment AR use by sales teams.

I experimented with different AR framework, and chose iOS ARKit, since it was the most stable at the time.

In retrospect, maybe I should have chosen Android's ARCore since it would have made distribution much easier.

I designed the app in Figma and developed it in Unity using iOS' ARKit library.
The app include features that help sales reps make measurements that are necessary to assess technical feasibility.
It also helps clients visualize their future installation before making any decision.
The app can take screenshots of the virtual installation and then take notes on it. All the captures can be shared in the Google Drive clients directory to facilitate later technical work.
I also made the app natively compatible with iPad.
The 3D models used in the app include markers that describe the different necessary safety areas that should be available.

  • User Interview
  • User Test
  • Workshop
  • Focus Group

I manage and conduct discovery phases, helping you know who your users are and what are the problems that really need solving.

Discovery can take many forms, from remote user interviews to field studies. I also organize workshops and focus groups to collect collective feedback.

UI Design
  • High Fidelity Mockups
  • Design System
  • Design Delivery

I design your product screens, with ergonomy and accessibility in mind.

I define how the different components should react to users interactions, their transitions and animations.

I also have experience creating and contributing to internal Design Systems.

User Testing
  • User Test
  • User Interview
  • Data Analystics

I can manage your user-testing phase, from recruitment to analysis.

I follow a rigorous process to make sure the tests are unbiased and the results convert implementable feedback.

Design Delivery
  • Design System
  • Design Specs
