Product Architecture

Shape the structure behind complex products so teams can make better decisions, faster.

I clarify domains, journeys and system boundaries so the product can scale without accumulating avoidable complexity.

Let's talk →

Consistency at scale

Unified experiences across products and platforms.

Faster delivery

Reusable building blocks and clear patterns.

Better collaboration

A shared language between design and engineering.

Long-term impact

Systems that evolve with your product.

WHAT THE WORK CAN INVOLVE

A practical architecture that connects the product language, its users and the teams who evolve it.

  • Architectural direction and evolution strategy
  • Domain and capability mapping
  • Information architecture and navigation model
  • End-to-end journey and service blueprint
  • Content and data model alignment
  • Platform and integration boundary definition
  • Architecture principles and governance model

ARCHITECTURE TRANSFORMATION

Different symptoms can share the same structural cause.

When the underlying product structure is unclear, friction appears across journeys, language and decisions.

WHAT PEOPLE EXPERIENCE

  • Disconnected journeys
  • Duplicated concepts
  • Navigation exceptions
  • Conflicting terminology

THE SHARED CAUSEUnderlying product structure

WHAT BECOMES POSSIBLE

  • Shared boundaries
  • Shared vocabulary
  • Coherent journeys
  • Clearer decisions

APPROACH

Start with the whole product. Focus where structure matters most.

Move from broad context into evidence-led investigation, then carry what you learn back into the map.

  1. 01LANDSCAPE

    Bring the whole product into view.

    1. 01

      Overall discovery

      Map products, users, journeys, domains and constraints.

  2. 02PRIORITY AREA

    Find where structure is creating the most friction.

    1. 02

      Identify opportunities

      Make structural tensions and areas of leverage visible.

    2. 03

      Prioritise

      Choose the problem where focused work can make the biggest difference.

  3. 03FOCUSED INVESTIGATION

    Zoom in before deciding what to change.

    1. 04

      Deep discovery

      Investigate the active structural problem with focused evidence.

    2. 05

      Decide

      Agree the boundaries, response and evidence for success.

  4. 04INTERVENTION

    Change the structure in its real product context.

    1. 06

      Execute

      Put the decision into practice across journeys, systems and teams.

  5. 05UPDATED LANDSCAPE

    Learn from the change and choose what deserves attention next.

    1. 07

      Learn

      Observe what changed and what the product reveals.

    2. 08

      Reprioritise

      Return learning to the opportunity landscape and begin the next cycle.

↺ Learning updates the landscape, so the next investigation starts with better context.

EVIDENCE

Product architecture in practice.

Selected work and thinking where product structure clarified journeys, boundaries and decisions.

Your Hiring Process Has More Users Than You Think

Most hiring processes are designed around the one person who gets the job. But everyone else leaves with an experience that can influence who applies next. What happens when we look at hiring as a service designed for everyone who participates in it?

CASE STUDY

Making a complex candidate journey explain itself

A ground-up rebuild of the candidate screening experience, separating the constraints we had to respect from the legacy behaviours we no longer needed to inherit.

CASE STUDY

Turning legacy complexity into a system teams could move forward with

I helped modernise a fragmented legacy product by clarifying its core patterns, introducing reusable design-system foundations, and creating a more consistent way for teams to make and scale product decisions.

RECOGNITION

Product architecture may need attention when…

  1. 01

    Journeys work independently, but they do not feel like parts of one product.

  2. 02

    Navigation keeps growing through exceptions and special cases.

  3. 03

    The same concept means different things in different areas of the product.

  4. 04

    Adding functionality requires changes to unrelated parts of the product.

  5. 05

    Teams disagree about where capabilities belong.

  6. 06

    Nobody can confidently explain how the whole product fits together.

START WITH THE FRICTION

Tell me where the product is becoming difficult to reason about.

We can trace what sits underneath the complexity and work out where clearer structure would make the biggest difference.
