Service

API and Systems Integration

Making systems that were never designed to talk to each other work as one, and stay working.

Why Partner with Us

What Makes the Delivery Different.

The same standards apply whichever service you start with.

Premium quality

Code reviews, automated and manual testing, performance and security checks before anything ships.

Seamless collaboration

Your tools, your standups, your board. We work inside your process rather than beside it.

Deadline driven

Scope is agreed in writing and dates are held. If something slips you hear it early, not at the deadline.

Clear and honest pricing

Written estimates before work begins, and no invoice that contains a surprise.

Senior engineers only

You get the people you met. No handover to juniors after the pitch.

Scalable by design

Architecture chosen for the tenth release, not just the first, so growth does not force a rewrite.

How We Deliver It

Four Stages, and You See the Software in All of Them.

01

Map

Every system, every field and every owner written down, including the spreadsheet somebody maintains by hand.

02

Contract

The API contract is agreed and documented before code, so both sides can build against it at once.

03

Integrate

Sync, retries, idempotency and error handling built for the day a third party is down, not just the happy path.

04

Monitor

Dashboards and alerts on the flows themselves, so a silent failure is not discovered by a customer.

What You Get
  • Documented API contracts in your repositories
  • A field-level map of what moves where
  • Retries, idempotency and a dead letter queue
  • Alerting on every integration, not just uptime
  • A sandbox to test against before you go live
  • Handover notes for whoever runs it next

Questions

Before You Ask Us.

The work queues and retries with backoff, and the operation is idempotent so a replay cannot double charge or double create. That is designed in, not added after the first incident.
