Integrations

Connect external platforms and internal systems without making your team the adapter between them.

Why this work matters

An integration is not complete when two APIs can exchange a successful example payload. It is complete when the systems disagree, an event arrives twice, a credential changes, a provider is unavailable or a record cannot be reconciled—and the business still knows what happened.

What I can take on

01

Clarify the source of truth, ownership and lifecycle of every important piece of data.

02

Design API, webhook or file-based connections around the actual guarantees of each provider.

03

Transform, validate and persist data so downstream work has a stable contract.

04

Add retries, reconciliation paths, observability and safe replay rather than relying on a happy path.

Usually a good fit when

  • People manually move information from one system to another.
  • A provider integration works until a real exception occurs.
  • A workflow depends on events arriving from several external platforms.
  • The business needs a dependable connection, not just a one-off script.

Probably not a fit when

  • A vendor already provides a stable native integration that meets the requirement.
  • There is no agreed source of truth for conflicting records.
  • The integration would create a new dependency without an owner for operating it.

How an engagement starts

01

Understand

Describe the process as it exists, including the workaround and the point where it breaks.

02

Shape

Turn the problem into a constrained system: scope, interfaces, states, risks and a first useful slice.

03

Build

Implement the system, connect it to production reality and leave behind something the team can operate.

Start with the real process

Discuss a workflow.

Bring the manual steps, the exceptions and what people currently do to keep things moving. That is enough to begin a useful conversation.
