APIs & Integrations

I design APIs and integrations the boring, durable way: idempotency, retries, webhooks, clear contracts, and event-driven syncs that replace fragile nightly batches.

this is you if…
  • You integrate with ERPs, payments, or partners
  • A nightly batch keeps breaking
  • Your public API breaks consumers when it changes
  • You need webhooks that actually deliver

What I do

  • API design & versioning
  • Idempotency & retry strategy
  • Webhooks & event streams
  • Third-party integration
  • Contract tests & docs

What you get

  • A documented, versioned API
  • Resilient integration services
  • Webhook delivery with retries
  • Contract & integration tests
  • Consumer migration guide

Common questions

  • Most work is fixed-scope or capped: after a discovery call we agree on a written scope, milestones, and a price before any code is written. Ongoing work runs as a monthly retainer with reserved days. You always know the number up front — no hourly meter running in the background.

  • No. I’ll work in your stack — I’m language-agnostic on principle. My “stack” page is where I’m fastest, not a list of requirements. For greenfield work I’ll recommend deliberately boring, maintainable choices and explain the trade-offs.

Book a 30-minute call. We’ll talk through what you’re building, what hurts, and whether I’m the right person for it. No charge, no pitch — and a scoped plan before any work begins.
