Meet Xavier: The Developer Behind Kalyxo
From the son of French travel agents to San Diego web developer, living the American Dream one website at a time.
Est. 2022 in San Diego
Bonjour! I'm Xavier
My love affair with America started early. As the son of French travel agents, I've been visiting the U.S. since I was a baby. Those trips planted a seed: the American Dream. That dream finally bloomed when I won the Green Card lottery and moved to San Diego in 2012.
In March 2021, I proudly became an American citizen. It was the culmination of a journey that started with childhood visits and grew into a lifelong commitment to this country and its entrepreneurial spirit.
After 6 years leading front-end development teams at agencies like Siege Media, I founded Kalyxo in 2022 with a simple mission: give small business owners the freedom to focus on what they do best while I handle their web presence.
Today, I help businesses across San Diego (and beyond) build websites that actually work. Fast-loading, mobile-friendly, and optimized to turn visitors into customers. All starting at just $150/month with $0 down, because great web design shouldn't require a second mortgage.
Why Kalyxo Exists
The Problem I Kept Seeing
Working at agencies, I watched small businesses struggle with their web presence. They'd either go without a website entirely, or pay $10,000+ for something that looked dated within a year. Many ended up with slow, broken sites that actually hurt their business.
It drove me crazy. Small businesses deserve better.
The Solution I Created
Kalyxo bridges the gap between "no website" and "overpriced agency." I offer the expertise of a senior developer with the personal touch of a local partner—all for just $150/month with $0 down.
Professional results. Personal service. Finally affordable.
How I Work Differently
I Speak Your Language
No tech jargon. I explain everything in plain English (or French, if you prefer!). You'll always understand what's happening with your website.
I Build for the Long Term
Using modern technologies like Astro and React, I create websites that stay fast and secure for years. Less maintenance, more peace of mind.
I'm Actually Here
Based in San Diego, I understand the local market. When you need support, you get me, not a call center. Real help from someone who knows your business.
I Care About Results
A beautiful website means nothing if it doesn't bring customers. I focus on performance, SEO, and conversions: the things that actually grow your business.
The Experience Behind Your Success
The Foundation Years
Started my career in Paris, building web applications for major French companies like ENGIE and working with global brands at Wunderman. Learned that good code is universal—but great service is personal.
The Agency Years
Led front-end development at Siege Media in San Diego, managing teams and optimizing websites for Fortune 500 companies. Mastered Core Web Vitals, accessibility, and what makes websites truly perform.
The Kalyxo Years
Founded Kalyxo to bring enterprise-level expertise to small businesses. Currently helping 15+ local businesses thrive online with custom websites, ongoing support, and strategies that actually work.
When I'm Not Coding
You'll find me spending time with my wife and our two kids, exploring San Diego's incredible beaches and parks. We love discovering new playgrounds and family-friendly spots around town.
I'm also passionate about helping fellow French-speaking entrepreneurs navigate the U.S. market, bringing a bit of that French attention to detail to American business hustle.
And yes, when everyone's asleep, you might catch me sneaking in a gaming session. (Hey, problem-solving is problem-solving, whether it's debugging code or defeating bosses!)
A Website Transformation I'm Proud Of
When USA Conseil came to me, their website was like a time capsule from 2004. This French travel consultancy had been serving clients for two decades, but their online presence wasn't reflecting their expertise. The challenge: Modernize everything while preserving the soul of their brand. The result? A complete transformation that honored their heritage while catapulting them into 2024.

This is what I do best: Take businesses with incredible stories and make sure their websites tell those stories beautifully and profitably.
