Slow APIs
Critical endpoints are becoming harder to scale, monitor, or maintain.
Backend systems
Fitzroy refactors services, builds APIs, and repairs integrations so core software becomes easier to change, observe, and operate.
Where we help
Service boundaries and APIs
Data and integration paths
Performance and failure handling
Authentication and access controls
Deployment and operational visibility
Technical debt reduction
When to engage
Delivery drag
New features take longer because core systems are tightly coupled.
Fragile integrations
Third-party systems break, fail silently, or lack clear ownership.
Production risk
Technical debt is creating reliability, performance, or scaling concerns.
Deliverables
Reworked services and APIs
Implemented changes with tests and clear interface contracts.
Reliable integrations
Explicit data flows, error handling, retries, and ownership.
Release and handover
Deployment changes, instrumentation, runbooks, and decisions recorded alongside the code.
Backend architecture diagnostic
Which dependencies, APIs, or operational risks are limiting delivery and reliability?
Typically two working weeks; fee, access, deliverables, and acceptance criteria agreed in the statement of work.
Review scope and deliverables →We can begin with one critical system boundary and define the next increment from measured behavior and delivery needs.
