Web, SaaS and mobile applications

A good application is more than an interface. It is a data model that survives five years of change, permissions you can explain to an auditor, and an admin panel the team actually wants to work in.

What we do

• SaaS platforms — backends most often in Java or Kotlin on Spring Boot (Node.js too), Next.js frontends. OAuth2 with MFA, billing, coupons, customer-facing APIs.
• Customer portals and admin panels — interfaces where customers manage their accounts and the team runs sales, support and processes. We build them so that the next internal tool is another tab, not another application.
• Mobile applications — React Native (Expo) for iOS and Android: maps, geolocation, push notifications, in-app purchases, multiple languages. We take the app through the whole App Store and Google Play release process.
• Backends for apps — Supabase or a custom API, PostgreSQL with PostGIS, serverless functions, end-to-end tests.

How we work

Short iterations with a working test environment from week one. Every change goes through a pipeline with tests — including mobile apps, where end-to-end tests protect against regressions that cannot be rolled back quickly.
