API Strategy and Systems Integration Consulting

CatalytIQ Systems helps organisations connect systems securely across cloud, legacy and modern platforms for seamless user and business experiences. I'm a Brisbane-based Technical Business Analyst, so the focus is on getting the requirements, data and design right before anything is built.

Who this is for

• Organisations with a growing number of point-to-point connections that are hard to change.
• Teams replacing or upgrading a core system that many other systems depend on.
• Organisations that want to expose data or services to partners or customers through APIs.

API strategy

• Mapping the systems you run and the data that flows between them.
• Deciding which capabilities should be offered as APIs, and to whom.
• Agreeing standards for API design, versioning, security and documentation.
• Weighing up integration platforms against custom builds.
• Defining ownership and lifecycle so APIs stay maintained.

Systems integration across cloud, legacy and modern platforms

Different situations call for different patterns: real-time APIs, event-driven messaging or scheduled batch transfers. Legacy platforms often bring constraints of their own. The aim is an integration approach that is consistent and supportable, rather than a growing web of one-off connections.

Integration requirements and design

• Data mapping between systems, including formats and reference data.
• Interface specifications that delivery teams and vendors can build against.
• Error handling, retries and reconciliation.
• Non-functional requirements such as volume, response time and availability.
• Test scenarios that cover the edge cases, not just the happy path.

Security in integration

Integrations are a common weak point. Each connection should use proper authentication, least-privilege access, secure secrets management and logging. See how client access and data are handled on engagements.

Integrating AI services

AI features increasingly arrive as APIs too. LLM integration applies the same integration discipline to connecting language models with your systems.
