Process

How it works

  1. 01

    We talk

    You tell me what you need, even if the idea is not fully defined yet.

  2. 02

    I propose a solution

    Together we define the features, budget and timeline before we start.

  3. 03

    I build

    You follow the project’s progress and can give feedback throughout development.

  4. 04

    Go live

    I test, polish, and support you to get the project online.

About

Behind the code

I’m Lucas, a freelance application developer based in Lille and available remotely.

I like turning an idea or a concrete problem into a simple, modern tool that is actually useful.

From websites to Discord bots, dashboards and interactive Twitch experiences, I build solutions around the project rather than forcing the project into a ready-made template.
