Tired of "heavyweight" websites that drive your customers away? 🚀
As a passionate developer based in Strasbourg, I help companies and agencies create ultra-high-performance web solutions, where standard solutions (WordPress, heavy CMS) reach their limits.
🛠 My secret weapon: CoreEngine
I developed my own framework, CoreEngine, designed for pure speed.
Radical Performance: Websites under 1MB, scoring 100/100 on Google Lighthouse.
Zero Technical Debt: No unstable plugins. Your site is robust, secure, and scalable.
Eco-design: Lightweight code for minimal server consumption.
💻 What I can do for you:
High-Conversion Landing Page Creation: Ideal for your Ads campaigns (loading speed = lower bounce rate).
SaaS & Business Tools Development: Custom interface design (Dashboards, management tools like JADBudget).
Performance Optimization (WebPerf): Audit and acceleration of your existing websites.
Maintenance & Peace of Mind: Clean code that is easy to maintain long-term.
🤝 Why work together?
Choosing my profile means getting the agility of a freelancer with the rigor of an engineer. Whether you're a startup looking for an MVP or a Strasbourg-based company wanting to boost its local visibility, I transform your technical needs into growth levers.
