It slows down as users grow
A backend built for a demo buckles under real traffic, and fixes mean a costly rewrite.

Accounts, data, payments and integrations built securely and ready to scale.
An app is only as good as what's behind it. We build the backend and APIs your app relies on, with secure authentication, a well-designed database, payments, notifications and integrations with the systems you already use, so it stays fast as you grow.

Sound familiar?
The problems we hear most often before someone asks us about APIs & backend.
02
Security as an afterthought
Weak authentication and exposed data put users at risk and the business in breach of privacy law.
03
Systems that don't talk
The app can't connect to your CRM, stock or billing, so staff copy data by hand.
What's included
01
API design
Clear, versioned APIs documented for your app and any future clients.
02
Authentication
Secure sign-in with email, social providers or SSO, plus roles and permissions.
03
Data model
A database designed for your data and queries, with backups and migrations.
04
Payments and subscriptions
Stripe or in-app purchases set up correctly, including receipts and refunds.
