Hi, I'm Johan πŸ‘‹

Fullstack Product Engineer based in Paris, France πŸ‡«πŸ‡·

I design and build software products end-to-end β€” from product thinking and application architecture to backend, frontend, automation and infrastructure.

I like working close to the product: understanding the problem, designing the right technical approach, building it, shipping it and keeping it reliable in production.

What I work on

  • Product engineering β€” turning business needs into maintainable software products
  • Full-stack development β€” web applications, APIs and internal tools
  • Software architecture β€” designing pragmatic and evolutive application architectures
  • Automation β€” workflows, integrations and operational tooling
  • Infrastructure & DevOps β€” Docker, Linux, cloud infrastructure, CI/CD and observability
  • Open source β€” building and maintaining developer-facing tools

Open source

A TypeScript library for generating structured data graphs from application data, built around the Schema.org vocabulary.

Currently one of the main open-source projects I'm working on.

Tech

TypeScript Svelte React Astro Node.js Bun Python PostgreSQL Docker Linux AWS

I also work with technologies such as NestJS, FastAPI, Laravel, Redis, Nginx and infrastructure automation depending on the product and its constraints.

Rootage

I'm co-founder and President of Rootage, a digital engineering studio focused on designing and building useful, reliable and maintainable digital products for businesses.

We work across software engineering, automation, data and infrastructure, with a strong focus on solving operational problems rather than adding unnecessary complexity.
