À propos de Jérémy

Senior PHP/Laravel developer working on backend systems in production.

Votre backend ne devrait pas ralentir votre produit.

J’interviens sur des systèmes PHP/Laravel déjà en production
→ quand ça devient lent, fragile ou difficile à faire évoluer.

Situations typiques

  • Les features prennent de plus en plus de temps
  • Certaines parties du code sont “intouchables”
  • Les bugs reviennent régulièrement
  • L’architecture est là… mais n’aide pas vraiment

Ce que je fais

  • Reprendre du code legacy sans bloquer la prod
  • Stabiliser avant de scaler
  • Ajouter de la structure là où ça apporte vraiment de la valeur
  • Rendre le code plus simple à faire évoluer

👉 Pas de rewrite inutile
👉 On améliore ce qui existe déjà

Ma façon de travailler

  • Onboarding rapide
  • Décisions pragmatiques
  • Code maintenable par l’équipe (bonne pratique).
  • Formation de l'équipe si nécessaire
Disponible en full remote (France, Belgique, Europe)
Possibilité de déplacement sur site ponctuellement.

English version

Your backend shouldn’t slow your product down.


I work on PHP/Laravel systems already in production
→ when things get slow, fragile, or hard to evolve.

Typical situations

  • Features take longer and longer to ship
  • Some parts of the codebase are “untouchable”
  • Bugs keep coming back
  • The architecture is there… but doesn’t really help

What I do

  • Improve legacy code without blocking production
  • Stabilize before scaling
  • Add structure where it actually brings value
  • Make the code easier to evolve

👉 No unnecessary rewrites
👉 Improve what already exists

How I work

  • Fast onboarding
  • Pragmatic decisions
  • Maintainable code the team can own
  • Team support when needed
Available for full remote work (France, Belgium, Europe)
Occasional on-site visits possible.
