🧠From Generative AI to Legacy Code
Fullstack developer for 12 years, first as Tech Lead, then as CTO on technically demanding SaaS projects.
My playground? The PHP ecosystem (Laravel, Wordpress, native code) and JavaScript (VueJS, Nuxt, jQuery), with a particular appetite for AI since its rise.
🎯 What truly motivates me
Working on concrete projects: I like to understand an existing system, analyze it, and evolve it without rushing it. Technical debt, refactoring, SQL optimization, or legacy migration don't scare me.
Being proactive: my experience with startups and business teams has taught me to estimate costs, plan, and translate technical challenges to non-technical stakeholders.
Applied innovation: I am simultaneously working on a personal project (cyberflair.net) where I use generative AI (OpenAI, DeepSeek) with Laravel 12 and MCP. I don't just follow trends, I experiment with them.
đź’Ľ What I can bring you
A dual skill set: equally comfortable with legacy codebases (PHP 5, procedural MySQL) and modern architectures (Laravel 10/12, VueJS 3, Tailwind, CI/CD deployments).
A transversal vision: I have held Tech Lead, Senior Developer, and CTO positions – which allows me to have a technical, organizational, and product perspective.
A genuine taste for support: I am used to working autonomously, but I also know how to organize small technical teams, conduct project reviews, and ensure rigorous follow-up.
