Business challenges
Why API & Middleware Architecture projects fail
01
Point-to-point integrations that break everything
Every new system is connected directly to every other system. Five platforms means twenty point-to-point connections. Change one and three others break. The architecture becomes unmaintainable within 2 years.
02
No API documentation exists
The integrations work — most of the time. But nobody knows how. The developer who built them has left. Any change carries significant risk because nobody understands what anything does.
03
No error handling or retry logic
APIs fail silently. Data stops syncing. Nobody knows for hours or days. Customer records are out of date across the business while the team works from stale information.
04
Integration governance does not exist
Different teams add new integrations using different standards, different authentication methods, and different error handling patterns. The landscape grows unmanageable within 2 years of the first integration.
What is included
Everything in this service
API Design
Design RESTful APIs with clear endpoint naming conventions, authentication standards (OAuth 2.0, API keys, JWT), versioning strategy, rate limiting, and documentation format. Every API designed to be maintained by a team, not just one developer who happens to know it.
Deliverables
How it works
Our delivery process
Integration audit
Map every current and planned integration — what connects to what, using what protocol, how reliably, and whether it is documented.
Architecture design
Design the middleware strategy and governance framework that eliminates point-to-point complexity.
API standardisation
Define and document the API standards every integration must follow going forward.
Build & test
Build integrations to the agreed standard with full error handling, retry logic, and monitoring hooks.
Governance handover
Deliver the integration registry, governance framework, documentation, and run a knowledge transfer session.
Success stories
Client results
Celumai replaced our 14 point-to-point integrations with a clean middleware hub. We went from spending 40% of engineering time on integration maintenance to under 5%. The governance framework means every new integration now follows a consistent standard from day one.
The API documentation they delivered is the first time our entire integration landscape has been fully documented. Two months after handover it has already prevented two incidents that would have been significant without it.
