Operational Questions

Absolute clarity on how we match your company's speed.

I lead every project personally. You have direct contact with me throughout the entire process, with clear updates and coordinated decisions at every stage.

Yes. I'm with you from start to finish: defining goals, structuring, designing, developing, testing, and final deployment.

Yes. They can be entirely under your name and control. If you prefer, I can also provide and manage the hosting for you.

I work with both. My primary focus is B2B / business, but I also build projects for professionals and personal brands.

It depends on the scope. A corporate site is usually ready between 3 and 6 weeks. For more complex platforms, I set a phased schedule.

We start with a diagnostic call. With that information, I'll present a clear proposal with scope, timelines, and investment required.
