Design Manager - Team Lead
2024

Led a cross-functional team of data scientists and UX designers to integrate AI into customer experiences for Docaposte.

We launched 30+ innovation projects in one year, including the design of LaPoste GPT, an internal GenAI assistant.

What I have learned:
AI is more than just chatbots
—It’s about solving real user problems with the right AI for the right job.

My missions:
- Advocated for user-centered AI, balancing technical feasibility with business value
- Ensured seamless collaboration between data science and design teams`

TLDR; ✨ Key wins

  • Built an internal offer mixing UX framing + AI prototyping

  • Prioritized business value over tech hype

  • Created design methods to support AI adoption at scale

  • Delivered POCs in 2 months average

  • Proved the value of AI even when GenAI wasn’t the answer

This initiative was a strategic bet—funded by the executive committee, built from scratch, and designed to infuse AI into every corner of the org.

One team, shared by all, built to serve everyone.

Funded by the executive committee, ensuring a budget independent of business units—effectively making it a free resource for BUs.

Staffing

  • Behind the scenes: 2 Data Scientists = peer-to-peer sparring

  • On projects: 1 UX + 1 Data Scientist, working side by side

  • For prototyping: 1 dedicated UI designer across all initiatives

Our offer

Ideation

Ideation to deliver innovative solutions and API-driven Proof of Concepts (POCs) to ensure reusability across projects.

Team missions: Field observation, Audit, Workshops, Target vision

POC

Prioritizing POCs based on business value and feasibility Diagnostic data : No data, no solution

Missions: UX Research, Workshop facilitation

  • Assessing the project’s data value potential

  • Ensuring the proper functioning of the AI solution

  • Providing a first, lightweight front-end experience

The challenge

Industrialization

Not covered by the executive committee’s budget, this became a major transformation challenge.

The key issue: avoiding the trap of working on POCs that never materialize—risking that the team’s expertise remains theoretical rather than delivering real impact.

Use case : LaPosteGPT

Generative AI for La Poste Group employees

Project Objectives:

  • Define the target vision for a unified platform as the go-to entry point for Generative AI tools.

  • Design and prototype the first version (V1) of La Poste GPT as well as the target vision for the platform.

Success Criteria:

  • A clear vision: The platform becomes an essential daily reflex.

  • Perceived value: The tool is indispensable in users’ workflows.

Methodology

Step 1 - Personas

With so many different employee roles, we grouped them into broad families to simplify the approach.

Questions informed by business insights into user needs:

  • Who are the target users?

    • All employees (personal assistant)?

    • Different teams with specific needs?

    • Both experienced and new users?

  • Is there existing user feedback or data available?

  • What are the users' expectations?

  • What current user problems are we trying to solve with this project?

“What if the future of AI in business isn't generalist, but specialized— and deeply trained?”

— Us at some point

But what if the real game-changer isn't just specialization, but how we centralize or integrate AI tools?

“Centralized platforms vs seamless integrations—what’s the best path to empower your teams and workflows?”

— Also us at another point

Step 2: The business goal in 2 workshops

Workshop A: Value Proposition Canvas – A format I love, especially once an MVP exists.

  • Prioritize one key persona: hybrid profiles who switch between client-facing tasks and preparation work.

La Poste GPT is the Group’s self-service generative AI platform


— modular, hybrid, built by and for La Poste employees.

Workshop B: Semantic Alignment Workshop
– We aligned all stakeholders word by word, mapping out a unified vision + the ideal user journey.

Just accessing the damn thing.
How do I even get to La Poste GPT? Is it an app? A URL? Does it work on my device? Are there restrictions?

We built the entire journey around one central question: “Do you have time?”

→ If yes: how do you use it?

→ If no: what’s stopping you?

→ And in both cases: are you satisfied?

Step 3: User research

  • Strong demand on computer only : all the other tools from the Group are only accessible on desktop

  • Strong need for their personal HR demands

These insights helped design our top features:

  • Usage Library

  • Rich, structured answers: Tables / Graphs / Offer comparison / Customer insights

  • for those who interact with clients directly: that they can have the direct link to subsctription links

Step 4: Deliverables

Guiding Principles of the Target Vision

  • Usage Library to guide users from the home page

  • Categorized, ready-to-use actions (or create your own!)

  • Pin your favorite use cases for quick access

  • Customization available for any user

  • Fully responsive experience

  • Voice input enables hands-free interaction. The vision? A truly conversational assistant you can even use on the move.

One Entry Point
A seamless, centralized experience—no more tool overload

  • Embedded in existing business tools

  • One single access across the company

  • Ask one question → AI picks the right sources

  • Optional: filter sources manually

  • Flag outdated or untrusted data

  • By default, answers use all trusted sources

Beyond GenAI

AI isn’t just about chatbots—
It’s about solving real user problems with the right AI for the right job.

— Our GenAI fatigue

Pure AI approach

You don’t necessarily need design on all AI projects

Use case:

The finance team needed a smarter way to predict customer payments and optimize cash management at scale.

—just a seamless algorithm embedded directly into existing BI tools. The “interface” is the prediction itself.

Sometimes, no interface is the best interface—when AI becomes a silent engine, driving real value behind the scenes.

✅ And it’s ok
