๐ŸงฉSystems Engineering & Integration

Systems that talk.
Business that flows.

When systems cannot talk to each other, people become the integration layer โ€” copying, reconciling and re-entering data. SquareX designs and builds the integrations that make your platform landscape work as one.

Why integration engineering?

Your systems should work as one.

Most organisations do not lack systems โ€” they lack connection. Data trapped in silos creates manual work, inconsistent numbers and slow processes that no single vendor can fix.

SquareX treats integration as an engineering discipline: designed interfaces, governed data flows and monitoring that detects breakage before the business does โ€” so the landscape grows coherent instead of growing new silos.

Can your organisation answer these with confidence?

  • How many manual re-keying steps exist between our systems?
  • What happens to the business when a critical integration fails?
  • Are our integrations documented โ€” or tribal knowledge?
  • Is there one trusted source for each key data entity?
  • Could we onboard a new system in weeks, not months?
  • Do we know the true cost of disconnected systems?
Service scope

What does the service cover?

Integration architecture and delivery โ€” from landscape blueprints to working, monitored interfaces in production.

Integration Architecture

The blueprint for how systems, data and events flow across your landscape โ€” patterns, standards and ownership.

API Design & Management

Consistent, versioned APIs with gateways, documentation and access control as standard.

Event Streaming & Messaging

Reliable asynchronous integration with queues, streams and event-driven patterns.

Legacy System Integration

Connecting ageing systems safely โ€” with adapters and fallbacks that respect their limits.

Data Synchronisation

Master data, replication and reconciliation so every system agrees on the facts.

Interoperability & Standards

Industry and public-sector standards designed in โ€” not retrofitted under pressure.

Integration Monitoring

End-to-end visibility of flows, failures and latency across the landscape.

Secure Data Exchange

Authenticated, encrypted and auditable data exchange internally and with partners.

Migration & Cutover

Controlled data migration with reconciliation and rollback paths.

Deliverables

What you receive

You receive working connections and the documentation to keep them that way.

Integration Blueprint

The reference architecture for your landscape โ€” patterns, standards and ownership defined.

Working Integrations

Delivered, tested and documented interfaces running in production.

Interface Catalogue

Every integration documented: owner, contract, dependencies and service expectations.

Monitoring & Alerting Setup

Dashboards and alerts covering every critical data flow โ€” before, not after, the first failure.

Runbooks & Handover

Operational documentation and training so your team can run and extend the landscape.

Our approach

An engineering-grade approach to integration.

Interfaces are designed, versioned and monitored like products โ€” not glued together under deadline pressure.

01

Map

Systems, data flows, dependencies and pain points documented across the landscape.

See the landscape
02

Design

Patterns, contracts and standards agreed before the first line of glue code.

Design the seams
03

Build

Implementations contract-tested, secured and hardened before production.

Contract-tested
04

Operate

Monitored, documented and evolved as systems around them change.

Kept alive
From advisory to implementation

One partner from architecture to working interfaces.

Integration needs both architecture and engineering. SquareX designs the landscape and builds the interfaces โ€” including the custom software and data flows around them โ€” so the platform landscape converges instead of fragmenting.

Architecture-led. Tool-agnostic.

SquareX selects integration technology to fit your landscape โ€” from lightweight API gateways to full event streaming โ€” never the other way around.

Which systems still refuse to cooperate?

Whether you are connecting a new platform, replacing a middleware layer or untangling years of point-to-point links โ€” start with a systems integration conversation.

Integration outcomes depend on third-party systems, vendor APIs and agreed interface contracts. SquareX documents dependencies, fallback behaviour and operational responsibilities for every delivered interface.
