Hire API Development Expert Who Designs for Developers

APIs are products too — with developers as the users. I design REST and GraphQL APIs, build integrations, and write documentation with 15+ years of experience making systems talk to each other reliably.

Why API expertise matters

Every company is an API company now.

Every company is an API company now — whether it’s your public developer platform, the backend your apps consume, or the web of third-party integrations holding your operations together. I’ve spent 15+ years designing APIs developers actually enjoy using, and integrating everything from payment gateways to ERPs.

Hiring an API specialist means getting versioning, auth, rate limiting, webhooks, and documentation right the first time — instead of discovering the gaps when partners complain or scale breaks things. I also rescue existing APIs that have grown organically into a mess. More on full-stack development, or start at hire me.

What you get

API expertise, end to end

  • REST APIs designed like products — Resource modeling, consistent conventions, thoughtful status codes and errors — APIs your consumers can learn in an afternoon.
  • GraphQL where it fits — Schemas, resolvers, and federation for apps that need flexible data fetching without endpoint sprawl. Chosen deliberately, not by fashion.
  • Third-party integrations — Stripe, CRMs, ERPs, logistics, marketing tools — connected reliably with proper error handling, retries, and idempotency.
  • Webhooks and event-driven design — Async architectures with queues and webhooks that keep systems decoupled and resilient when traffic spikes.
  • Documentation developers love — OpenAPI specs, guides, and runnable examples. Great docs cut your support load and speed up partner onboarding.
  • Security, versioning, and limits — OAuth2, API keys, rate limiting, and a versioning strategy that lets the API evolve without breaking consumers.
How it works

From mapping to launch

  1. Integration mapping

    We map every system, data flow, and consumer of the API — internal and external.

  2. API design first

    You review the OpenAPI spec before code exists. Design disagreements are cheap at this stage, expensive later.

  3. Build and test

    Implementation with contract tests, load tests, and sandbox environments your consumers can integrate against early.

  4. Docs and launch

    Published documentation, migration guides for existing consumers, and monitoring from day one.

FAQ

API questions, answered

REST or GraphQL — which should we use?

REST for most cases — it’s simpler to cache, monitor, and evolve. GraphQL when clients need flexible data shapes, like complex dashboards or mobile apps. I’ll recommend based on your consumers, not trends.

Can you integrate our systems with a specific tool?

Very likely. I’ve integrated payment gateways, CRMs, ERPs, and dozens of SaaS tools. Tell me the systems on a discovery call and I’ll confirm feasibility — including when an off-the-shelf connector beats custom code.

How do you document APIs?

OpenAPI specs as the source of truth, plus guides, authentication walkthroughs, and runnable examples. Your partners should integrate without ever emailing you.

Can you fix our existing messy API?

Yes. I audit versioning, auth, error handling, and performance, then stabilize the highest-pain areas first — usually without breaking existing consumers.

How do you handle API versioning?

URL or header versioning with a clear deprecation policy: new versions ship alongside old ones, consumers get migration guides and generous timelines. No surprise breakages.
