API development & integrations

Make your systems talk to each other.

Most businesses run on several tools that don't share data. I build clean APIs for your web and mobile apps and connect the platforms you already use, with queues, retries and logging so integrations keep working when a third party has a bad day.

What I can build for you

REST APIs for mobile and web

Documented, versioned APIs with secure authentication.

Payment integrations

Gateways, webhooks and reconciliation.

Booking and quoting engines

Multi-step quote-to-booking flows with live pricing and availability.

Affiliate and marketing platforms

Tracking, commissions and partner integrations.

CRM, SMS and email

Sync customers and send notifications automatically.

Reliable background jobs

Queues, retries and monitoring so failures get noticed and fixed.

  2. Clear proposal. Scope, milestones and a fixed price or monthly plan, in writing.
  3. Build in the open. Regular demos and progress updates; you see working software early.
  4. Launch and support. Deployment, monitoring and ongoing improvements after go-live.

Common questions

Can you integrate a platform that has poor documentation?

Yes. I've worked with plenty of under-documented APIs. I test thoroughly and add logging so problems are visible instead of silent.

Do you build APIs for mobile apps?

Yes. I build and document APIs for Android and iOS apps, including authentication, push notifications and offline-friendly endpoints.

What happens when a third-party API goes down?

Integrations run through queues with retries and alerts, so temporary outages don't lose data and real failures get flagged.
