API development

Reliable REST and GraphQL APIs, webhooks and integrations.

Mobile apps, partners and internal tools all depend on your API. I design clear endpoints, document them, test them and put rate limits, logging and versioning in place, so other teams can build on top without guessing.

What's included

  • API design and OpenAPI documentation
  • REST or GraphQL endpoints
  • Webhooks and event-driven jobs
  • Integrations with CRMs, payment and shipping providers
  • Automated tests and staging environment
  • Rate limiting, logging and error tracking

How a project runs

Four stages, clear checkpoints, no surprises on the invoice.

  1. Discovery

    A call to understand the business, the users and what success looks like. You get a written scope, a timeline and a fixed quote or an hourly estimate.

  2. Plan and design

    Architecture, data model and screens agreed before any heavy coding starts, so changes are cheap while they still can be.

  3. Build

    Short cycles with a live preview link you can click through every week. You see progress, not status reports.

  4. Launch and support

    Deployment, monitoring and a handover with documentation. Then a support window, or ongoing maintenance if you need it.
