An app you cannot build on a template
Bespoke business processes (approval workflows, multi-tenant tenancy, internal dashboards) do not fit into a generic SaaS.
I build dedicated web applications on Next.js. Full control over logic, schema and integrations. Scalable from day one.
Mobile apps (PWA)
Looking for a mobile app for your business? In most cases you don't need a costly native app. A PWA (Progressive Web App) behaves like a mobile app (it installs on the phone's home screen, works offline and can send push notifications) yet ships faster and cheaper, because one codebase covers web and mobile.
I build PWAs with full offline and caching support: install from the browser, push notifications, works without signal. The scope follows what your customers actually use.
Three pillars of a web application
What clients expect from a custom application in 2026.
Performance
An app that does not slow down when 10 users become 10,000. Load-tested before launch.
Security
Login, roles and permissions, every input checked, change log. Customer data safe from day one.
Scalability
Each of your customers gets their own separated space. Heavy jobs run in the background, and you see a problem before a user reports it.
