Integration & applications

Middleware and integration

Integration architecture, API lifecycle, event design and estate rationalisation.

Capability in business terms

Why this capability matters

An interface can succeed technically and still fail the business. Ownership, retries and reconciliation are design decisions, not operational afterthoughts.

What we typically scope

Integration architecture, API lifecycle, event design, estate rationalisation, hypercare and run.

How we approach the work

Make the contract explicit before the code, and instrument before you investigate.

Work we take on

Example engagement — illustrative. Typical scopes of work, not named client case studies.

The interface nobody owns

Why it happens
A point-to-point interface built by someone who has left moves a file three systems depend on. No documentation, no monitoring, no owner.
How we work it
Instrument invocations for thirty days from gateway, file-transfer and database logs; identify real consumers; write the data contract the interface implicitly encodes; then retire, rebuild or adopt it.
What you end up with
Evidence of actual usage, a written contract with named owners on both sides, and a decision made on data rather than fear.

Intermittent failures nobody can reproduce

Why it happens
An integration fails roughly twice a week, always recovers on retry, and no one has found the cause.
How we work it
Correlate failures against upstream deploy, load and batch windows; add correlation IDs end to end; capture full payloads for failing transactions; test the hypothesis under load.
What you end up with
A root-cause analysis with evidence, a fix or a documented mitigation, and instrumentation that catches the next one immediately.

Rationalising an estate that grew by accretion

Why it happens
Four integration technologies, roughly two hundred interfaces, and a licence renewal in six months.
How we work it
Inventory every interface with owner, volume, criticality and technology; rank by fragility and business impact; model consolidation scenarios against licence and run cost; sequence by risk.
What you end up with
A full estate inventory, a fragility ranking, and a consolidation roadmap with costs and a sequence.

Moving from batch to events

Why it happens
Overnight batch no longer meets the business's latency expectations, and a rewrite has been proposed.
How we work it
Identify the flows where latency actually changes a decision, introduce events alongside batch for those only, design idempotency and replay, run both in parallel until reconciliation matches, then retire the batch path.
What you end up with
Event-driven flows where they earn their place, with batch retired on evidence rather than switched off on faith.

An API programme with no lifecycle

Why it happens
APIs are published by several teams with inconsistent auth, versioning and documentation, and consumers keep breaking.
How we work it
Define standards for auth, versioning, deprecation and error semantics; put a gateway in front for policy; publish a catalogue; set a deprecation policy with notice periods; grandfather existing APIs on a timetable.
What you end up with
A published API standard and catalogue, a deprecation policy with dates, and consumer breakage that becomes a scheduled event.

How we approach the work

Understand the estate

Map dependencies, constraints, decision owners and the current operating model.

Make the decision explicit

Record options, risks, costs and acceptance criteria before implementation.

Make the handover usable

Document changes, operating instructions and the remaining risks.

Delivery is subject to specialist fit and availability.

Start with clarity.
