Platform · development & technical maintenance
A whole country
in one app.
holandia.app helps Poles in the Netherlands with news, work, paperwork and language. I build and maintain the platform: the apps in both stores, the AI features and everything running underneath - from database to daily automations.

I build and I maintain
I do not hand over and disappear.
What is listed below I do every month - that is why these projects are still running.
Hosting & deploysPushing new versions live without downtime - with a rollback plan.
Updates & securityCore, plugins and dependencies kept current; nothing sits still for years.
SEO & findabilityStructure, speed, sitemaps and multilingual setup that keep adding up.
BackupsAutomatic, tested, and genuinely restorable when it matters.
MonitoringI notice before the client calls - logs, uptime, error reports.
Further developmentNew features as the business grows. A site is not an end point.
