API Integration Consulting
Discovery through first production cutover for teams connecting partner or internal APIs who need clear contracts and a staged rollout.

OakCore Development Consulting
We design how your systems talk to each other — mapping integrations, shaping backend services, and leaving your team with contracts and runbooks they can own.

When integrations stall, delivery stalls
Product teams often inherit half-finished API work: brittle webhooks, unclear ownership of payloads, and backends that grew by accident. OakCore sits with your engineers and product leads to clarify boundaries, sequence the work, and design services that stay maintainable after we leave.
Our flagship offer is API integration consulting — discovery through first production cutover — with backend service design and integration audits available as companion work.

Flagship: API Integration Consulting
For teams connecting payment processors, CRMs, logistics partners, or internal services who need a clear contract map, staged rollout, and hands-on design review — not a slide deck of vague principles.

Work that usually sits beside an integration programme — pick what matches your current bottleneck.
Backend Service Design
Shape service boundaries, ownership, and interfaces so new integrations do not collapse into a single brittle codebase.
Integration Audit
A focused review of existing integrations — webhooks, retries, contracts, and ownership gaps — with a prioritised remediation list.
From recent engagements
Specific outcomes from Australian teams who brought us into live integration work.
“OakCore redrew our partner API map in the first week. We still had to negotiate rate limits with the carrier, but the failure modes were finally written down instead of living in Slack.”Priya N. · Head of Engineering, Melbourne logistics firm
“The backend service boundaries they proposed felt conservative at first. After two release cycles we were glad — onboarding a second marketplace didn’t require rewriting the original service.”Marcus T. · Product lead, Sydney retail stack
