JarrahSoft: Shopify stores, custom websites and web apps

Backend & API development

The part nobody sees, built so everything else can rely on it.

APIs, integrations and business logic that stay fast under load: multi-tenant SaaS, POS systems, payments and mobile backends.

We design and build the backend systems products run on: APIs shared by web and mobile apps, payment flows that never double-charge, queues that keep slow work off the request, and integrations with the tools you already use.

Deliverables

  • REST APIs for web and mobile
  • Multi-tenant SaaS architecture
  • Payment and webhook handling
  • Queues and scheduled jobs
  • Third-party integrations
  • Tests and API documentation

A good fit if

  • You are building a web and mobile app on one API.
  • You need payments, webhooks or third-party systems connected reliably.
  • Your current backend is slow or hard to change.
  • You are turning an internal tool into a multi-tenant SaaS.

What's included

API design
Clear, versioned endpoints with token auth (Sanctum) shared by web and mobile clients.
Multi-tenancy
Tenant scoping on every query so one customer can never see another’s data.
Payments
Stripe, local card rails and mobile wallets, with webhooks and idempotent processing.
Background work
Queues, retries and scheduled jobs for imports, emails and syncs.
Integrations
Google APIs, Shopify, OpenAI, maps, couriers and scraping services.
Quality
Automated tests and API docs so changes ship with confidence.

How it runs

Model
We map the data, users and edge cases before writing code.
Contract
API endpoints agreed with whoever builds the clients.
Build
Endpoints, jobs and integrations, tested as we go.
Harden
Load checks, logging and alerts before go-live.

Frequently asked questions

Can one API serve both our website and app?
Yes. Several of our builds use one Laravel API for a React web app and an Expo React Native app.
Do you write tests?
Yes. Critical flows like payments and permissions get automated tests.
Which databases do you use?
MySQL and PostgreSQL most often, with Redis for caching and queues.
