L'Antoine

Something beautiful, built to last.

We design and develop web experiences with the care of a craftsman — for the baker who wants their first online presence, and the company ready for something more ambitious.

A few project types we work on

Artisan bakery Showcase & ordering
Property agency Listings & search
Fashion boutique E-commerce

What we build

From a first online presence to something more complex — every project starts with listening, and ends with something that works.

How we work

No methodology slides, no project management theatre. Just clear heads, honest conversation, and work that moves forward.

01

Listen

We start by understanding what you actually need, not what we think you need. A conversation, not a questionnaire.

02

Shape

Ideas become structure. We map the architecture, the flows, the content — before a single line of code.

03

Build

Development happens in the open. You see progress, you can ask questions. Nothing lands as a surprise.

04

Deliver

We hand over something finished — documented, tested, and ready for the long run. Then we stay close.

Human

Behind every project is a person. We build relationships before deliverables.

Honest counsel

We'll tell you what we think, even when it's simpler or cheaper than what you asked for.

Complexity, made light

Technical depth should never feel intimidating. We translate it.

Responsive

A question asked is a question answered. We're present throughout.

What we work with

The craft is in the choices. We work with tools that are proven, maintained, and matched to the scale of what you're building.

Front-end

The visible side

Designed to be felt, not just seen

Interfaces that are smooth, accessible, and precise — from first impression to last interaction.

React Next.js TypeScript Tailwind CSS Astro

In plain terms What you see on screen — its layout, its speed, how it responds when you tap or click.

Back-end

The engine room

Built for real conditions

The logic behind the interface — robust, well-structured, ready to scale when the time comes.

Node.js PHP 8 Express REST API GraphQL

In plain terms The part that processes requests, stores information, applies rules, and sends back what you need.

Database

Where things are kept

Structured to retrieve, structured to evolve

Data modelled with care — fast to query, safe to grow, clear to maintain.

PostgreSQL MySQL 8 MongoDB Redis Prisma

In plain terms Where your content, users, orders, and everything else lives — and how fast it can be found.

APIs & Integrations

Connected

Platforms rarely stand alone

We wire systems together cleanly, reliably, and with documentation that holds up over time.

Stripe Notion Airtable Webhooks Custom REST

In plain terms Making your site talk to your payment provider, your CRM, your booking tool — without losing anything in translation.

Performance & Security

Built to hold

Speed is a feature. Security is a foundation.

Neither is an afterthought. Both are built in from the start, not bolted on at the end.

Lighthouse 95+ HTTPS/SSL OWASP Rate limiting CDN / Caching

In plain terms A site that loads fast, doesn't leak data, and doesn't break under pressure.

Advanced AI Workflows

State-of-the-art tooling

The unfair advantage

We use the most capable AI systems available to accelerate development, improve quality, and open possibilities that weren't accessible before.

LLM integration Semantic search RAG pipelines AI-assisted dev

In plain terms From automating complex tasks to building intelligent features into your product — thoughtfully applied, never for show.

Let's talk about
your project.

No pitch decks. No automated replies. Just a real conversation about what you're building.

A personal response

Every message is read and answered by Mathieu, directly.

No jargon

If something technical needs explaining, we will. Plainly.

No pressure

We'll tell you honestly if we're the right fit. And if we're not, we'll say so.
