Who's behind Lumea
One point of contact,
the one who codes.
I'm Karim Sehil. By trade, I'm a Cyber Security Analyst specialising in Application Security: my day job is spotting what can weaken a piece of software.
Alongside that, I design and code websites and applications myself, all running in production: Avelyo for quotes and invoices, Aquarys for water laboratories, Vigie for on-site staff check-in.
With Lumea, I'm the one you talk to, the one who builds and the one who puts it online. No middleman, and security built in from the start.

Process
Simple for you,
demanding for me.
Four steps, zero jargon. You always know where your project stands, what it costs and when it ships.
01
Discovery
A free conversation to understand your business, your goals and your customers. Then you get a written proposal: scope, timeline and a fixed price.
02
Design
A faithful mockup of your future site. We iterate together until every screen is exactly what you pictured — or better.
03
Development
Your site comes to life: fast, fluid, polished on mobile and on a large screen. I show you the progress as it goes.
04
Launch & follow-up
Going live, domain name, baseline SEO. And I stay reachable after launch.

FAQ
The questions I get most often.
From €490 for a one-page marketing site (Starter plan) and €890 for a multi-page site (Business plan); web apps are quoted on request. After a free first conversation, you receive a written proposal with a fixed price. See pricing →
It mostly depends on your content and your feedback. The timeline is written in the proposal, before you commit to anything. Web apps take longer: they come with a detailed schedule from the proposal.
For small updates (opening hours, prices, photos), send them over and I'll handle it. If you want to edit everything yourself, we plan an editing tool in the quote.
The basics are included: well-structured pages, fast loading, titles and descriptions for Google, local information. Nobody can honestly guarantee you a spot on Google, though, and I won't.
I stay reachable: fixes, small improvements, questions. For regular follow-up, there is a monthly maintenance plan.
Not at all — it's actually common. I help you structure your content, write the key copy with you, and can create a simple, coherent visual identity to go with your site.
