Description

Do you need a professional website that converts, or a custom web application? I build both.

I develop in Next.js/React: fast and optimized showcase sites, landing pages, and complete web applications (online booking, Stripe payments, admin dashboard).

No page builder, no bloat. Clean code, delivered fast.

My 3-step process: we chat for 20 min to scope the project, I prepare a mockup, we put it online.

What I deliver:

Showcase website in 7 business days

Web application / SaaS: timeline depends on scope, defined together

Each project includes Google My Business configuration

Ideal for: Small and medium-sized businesses, startups that want a serious online presence or a custom business tool.
