Alexis Thierry-Bellfond / 2026Interface → Logic → Runtime

I'm Alexis, a full-stack developer based in Paris. I turn real-world constraints into web, mobile and business software products.

Start the journey

Three living products

THREE PRODUCTS.THREE MECHANICS.

Each project has its own identity, its own mechanics and its own vision.

Independent student product · Active

EpiTime

A timetable that follows the student, not the other way around.

A cross-platform timetable for EPITA, available on the web, as a PWA and on Android. Microsoft sign-in, offline caching, course reminders and widgets keep the day readable even when conditions are not perfect.

Useful information remains one gesture away, with or without a network connection.

React Native / PWA / Python / MSAL / React

Community platform · Since 2021

WorkshopRessources

Community knowledge transformed into a product people can navigate.

A long-running platform for game-content creators, evolving from an initial PHP version into a modern service with accounts, structured resources, search and community publishing.

Years of iteration transformed a personal idea into a maintained platform.

React / OAuth / Python / MySQL / Moderation

README Studio

A GitHub profile editor that turns a blank page into a personal surface.

A local-first visual editor for GitHub profile READMEs. It assembles blocks with drag and drop, lets each be tuned in an inspector, previews the result in GitHub light or dark mode and exports clean Markdown.

A GitHub profile can be designed and published without an account, a backend or Markdown friction.

My method

THE INTERFACEIS ONLY ONE LAYER.

I like projects that demand the entire chain: framing the need, composing the interaction, modelling the data, making creation easier and reducing complexity.

My job is not to accumulate technologies. It is to make a complex system understandable, reliable and useful to the person using it.

  1. 01

    Understand the real constraint

  2. 02

    Design the complete journey

  3. 03

    Plan for imperfect conditions

  4. 04

    Diagnose with evidence

  5. 05

    Ship, observe, refine

WHERE I TESTTHE LIMITS.

Smaller systems allow me to explore another constraint, another runtime or another way of making feedback tangible.
