How we work

Simple, professional, and designed to fit product teams without fuss.

Do you work with UK and international clients?

Yes. Work is typically performed remotely from the UK. Any jurisdiction-specific requirements can be discussed up front.

How is work scoped?

We prefer a statement of work (SOW) for a defined period or set of deliverables. For ongoing support, we can also work on a time and materials basis with clear written scope and priorities.

Do you provide documentation and tests?

Yes. Deliverables normally include appropriate automated tests and concise documentation where it improves long-term maintainability.
