I turn your idea into a custom web application that runs in the browser

Beyond a corporate site; a real application with user logins, a database, calculations and business logic. I build custom web software from scratch with a modern, fast (Core Web Vitals-friendly) and scalable architecture.

The problem

Sound familiar?

An ordinary website isn't enough; your business has its own logic.
Templates start limiting you as you grow.
You need real-app features: user accounts, calculations, data flows.
Slow, clunky solutions lose both users and Google.
The solution

A fast application written around your business

I listen to what you want to do and build the app around it. Because I work with modern tools (Next.js, TypeScript), it's both fast and secure; speed and being found in search are considered from the very start. When new features and more users come later, it grows without pain. Since the same person handles design and code, you never feel a gap between the two.

FAQ

Frequently asked questions

How is it different from a website?
A site shows information; an app does work. If there are logins, data processing, calculations and logic, it's a web application.
What technology do you use?
Modern, widely-used and long-lived technologies like Next.js, TypeScript and PostgreSQL. This site runs on the same foundation.
Can I grow it later?
Yes — the architecture is built to scale from the start; it expands painlessly as features and users grow.
Do you design it too?
Yes — design and code come from the same hand. That's why the interface is both beautiful and usable, with no gaps.
