Mobile Backend, APIs and Cloud Infrastructure
Secure, scalable backends that power your apps — auth, data, payments, notifications and analytics.
Your app's front end is what users see; the backend is what makes it trustworthy. Authentication that does not break, data that does not corrupt, payments that reconcile, and notifications that arrive — these are backend concerns, and getting them wrong is what destroys app reviews.
We build backends on the right tool for the scale: Firebase for speed to market and managed infrastructure, Supabase or Postgres for relational data and fine-grained security, or a custom Node.js service where business logic demands it.
Every backend includes authentication with proper token handling, role-based permissions, rate limiting, audit logging, automated backups and monitoring — regardless of the platform chosen.

Typical backend uptime
The problems we fix
Insecure authentication
Tokens stored insecurely, no refresh strategy and missing permission checks expose user data and API keys.
Data that scales badly
Schemas designed for a prototype collapse under real query patterns, producing slow lists and failed writes.
Unmonitored failures
Without logging and alerting, backend errors are discovered through one-star reviews.
How we fix them
Secure auth architecture
Short-lived tokens with secure refresh, device binding, revocation and role-based authorisation checks server-side.
Query-driven data modelling
Schemas and indexes designed against your real read and write patterns, with pagination and caching throughout.
Observability by default
Structured logging, error tracking, performance tracing and alerting on error-rate and latency thresholds.
