01
We define the purpose of the project, the main users and the content we need before deciding how to build it.
02
We organize the content and the main journeys, then review the visual direction together before implementation.
03
I develop the interface in manageable steps, checking navigation, content and behavior as the project takes shape.

We review the agreed scope, prepare deployment and document the practical steps for editing and maintaining your website.

A few things you might be wondering
Straightforward answers, before we write the first line of code.
01How do we start a project?
Tell me what you want to build, who it is for and any timeline you have in mind. We clarify the goals first, then agree on a written scope and proposal.
02What kind of websites do you build?
Business websites, portfolios, content platforms and custom web interfaces. I work with React, Next.js and JavaScript, choosing the structure around the needs of each project.
03Will my website work on mobile?
Mobile, tablet and desktop layouts are part of the development scope. Navigation, text and controls are designed to adapt to different screen sizes.
04How long does a project take?
It depends on the number of pages, the content and the required integrations. After reviewing those details, I propose a timeline with clear milestones and review points.
05Can you improve a website I already have?
Yes. We can review its structure, content, performance and usability, then prioritize the changes that make the most sense for your goals.
06Do you work with international projects?
