Frequently Asked Questions
What industries does Mayordomo Digital specialise in?
Mayordomo Digital specialises primarily in financial technology (FinTech) and
enterprise software engineering. Robert Butler has delivered production systems
for ClearBank (real-time banking), Paymentsense (payments infrastructure),
NewDay (consumer credit), and ASOS (retail e-commerce), bringing
regulated-industry rigour to every engagement.
What cloud platforms does Mayordomo Digital work with?
We specialise in Microsoft Azure and cloud-native patterns: containerised
microservices with Kubernetes, Azure Service Bus, Azure Functions, and Azure
DevOps CI/CD pipelines. Architectures are designed for portability so clients
are never locked into a single vendor.
How does Mayordomo Digital approach site reliability engineering (SRE)?
We implement full-stack observability using OpenTelemetry, define Service Level
Objectives (SLOs) and Service Level Indicators (SLIs), and build automated
alerting with self-healing runbooks. The goal is 99.99% availability through
proactive engineering rather than reactive firefighting.
Can Mayordomo Digital assist with financial services compliance?
Yes. With hands-on experience at FCA-regulated institutions, we understand
PCI-DSS, audit-trail obligations, and financial data governance. We design CQRS
and event-sourced architectures where compliance is a natural consequence of the
system design rather than a retrospective bolt-on.
How do I engage Mayordomo Digital for a project?
Email robert@mayordomo.co.uk or
connect on LinkedIn for an initial conversation. We typically begin with a
no-obligation scoping call before proposing an engagement model — whether
fixed-scope delivery, retained advisory, or embedded consultancy.
