Freelancer profile translated to English.
Back to original languageAbout Matthieu
You have a digital product that works but is starting to show its limits.
Your app slows down under load. Your junior team is hesitant to touch the code.
Or your internal tool is standing, but everyone is afraid to touch it.
This is exactly the kind of situation I step into.
Full-stack developer with 17 years of experience (Symfony, React, PHP, API Platform),
I support Reunion Island SMEs who need a senior technical perspective without hiring a full-time CTO.
I intervene in two situations:
→ Your digital product is growing too fast for your team. The app is sluggish, bugs are piling up, customers are complaining. Your junior team is doing its best. You need someone to structure, optimize, and secure, without redoing everything.
→ Your aging internal tool is becoming a risk. Developed 5 to 15 years ago, it is critical but fragile. Each modification is expensive. The developer who knew it has left. You need to regain control gradually, without breaking what works.
No jargon. No systematic overhauls.
An honest audit, concrete recommendations, and support for your team to implement the right changes.
