Back to original languageAbout Calixte
Freelance developer specializing in web performance. I help product teams deliver faster, more secure, and more profitable websites — pages that convert and satisfied customers.
Losing customers due to a slow website or a fragile back-end. I intervene to diagnose, prioritize, and fix critical points (API, response times, security) to transform technical performance into measurable business results.
What I do specifically:
- Quick diagnosis and prioritization of high-impact actions.
- Back-end and front-end optimization to reduce loading times and errors.
- Iterative delivery to validate impact from the first weeks.
Typical proof and results:
50% reduction in loading time and +25% conversions on an e-commerce site.
Testimonial: “In 6 weeks, Calixte stabilized our APIs and increased our conversion rate.”
Available for short missions or long-term support.
Simple action: book 20 minutes for a free audit — I'll send you a clear and prioritized action plan.
