About

Less rework, fewer surprises in production

Most expensive mistakes in software start as a misunderstanding. My job is to find them before a line of code is written.

I sit between the business and engineering. I run discovery and refinement, model processes in BPMN and UML, write user stories, use cases and API specifications, and keep every change traceable back to the reason it was requested — so product owners, architects, developers and QA are all working from the same picture.

I have done this in large enterprise programmes and for an early-stage startup. Outside the day job I own nine iOS apps end to end, which keeps me honest about the other side: prioritising a backlog, making trade-offs and living with them in production.

Open banking

Led the requirements for an Open API that lets banks offer third-party services inside their own digital banking — the contract partners and internal teams build against.

Payments without the guesswork

Mapped how an undocumented payments system and internal portal really worked, then helped redesign their APIs so the team could change them safely.

E-commerce at scale

Requirements across web and mobile for a large platform, including non-functional requirements and end-to-end test cases spanning CRM, ERP and CMS.

A crypto product from zero

Shaped the first release of a startup: product vision, technical requirements and the scope of phase one.

What I do

How I can help your team

Requirements & discovery

Stakeholder interviews and workshops, refinement sessions, user stories and use cases, SRS and vision & scope documents, and change requests managed with full traceability.

APIs, integrations & data

API specifications in Swagger, BFF and microservice documentation, cross-system impact analysis, non-functional requirements, and data platform work with SQL.

Agile product ownership

Product and sprint backlogs, estimation and prioritisation, risk management, and stepping in as Scrum Master when the team needs one.

Side projects

Nine iOS apps on the App Store

The same skills, applied to my own products. I define, prioritise and ship these apps end to end — driving theory for five countries, a habit tracker, a meditation app and a flag quiz.
