Integration Engineering

Systems that actually talk to each other.

We design, build and maintain the APIs and integrations that move data between the systems your business runs on, so your team stops doing it manually.

What’s included
  • RESTful and GraphQL API design and development
  • Partner API integrations (payments, CRMs, ERPs)
  • Event-driven architectures with webhooks and queues
  • ETL and reverse-ETL pipelines
  • Workflow automation and idempotency
  • OpenAPI / AsyncAPI specifications
  • Authentication and rate limiting
  • Observability and audit logging
Outcomes you should expect

Fewer manual hand-offs

Automated flows replace spreadsheets and copy-paste.

One source of truth

Data reconciled between systems with idempotent, replayable pipelines.

Integrations you can trust

Every external call is retried, logged and monitored for drift.

How engagements are scoped

A discovery sprint, a written proposal, then we ship.

We don’t publish list prices because no two engagements are the same. Every project starts with a short, paid discovery so you and we can agree on scope, timeline and cost before we write any production code.

Start a discovery sprint
01

Discovery sprint

A short, paid engagement where we map the problem, review any existing code or systems, produce an architecture brief and deliver a written proposal with scope and pricing you can act on.

02

Scoped build

Once you accept the proposal, we ship against written scope and milestones. Weekly demos, transparent progress, no open-ended hourly meters.

03

Operate or hand over

After launch we can run the system alongside you, iterate on it under a retainer, or transition it cleanly to your team with documentation and knowledge transfer.

Routinely. We’re comfortable integrating with SOAP endpoints, flat-file exchanges, SFTP drops and vendor APIs that were last updated in 2014. We wrap them in clean, tested boundaries so the rest of the system doesn’t have to care.
Yes, from auth and rate limiting to developer portals, schema registries and OpenAPI-driven client generation. We’ve delivered internal API platforms for both fast-growing startups and enterprises modernising a service-oriented architecture.
Both, depending on the problem. GraphQL is great when you have many clients with different data needs. REST is usually simpler for partner-facing APIs where predictability and caching matter most.
Every integration we build assumes the external service will eventually fail. We implement retries with exponential backoff, circuit breakers, idempotent replay and structured alerting so partial outages don’t cascade into yours. Every integration has a documented fallback behaviour (queue for later, serve from cache, page on-call) agreed during design, so the system’s response to a vendor outage is a deliberate choice and not an accident.
Signed webhook verification on every request (HMAC where the vendor supports it, mutual TLS where they don’t), IP allowlists when the vendor publishes a static egress range, replay protection with timestamps and nonces, regularly rotated secrets, and structured audit logging of every received webhook for investigation.
