About

A designer, creator
and lifelong learner.

I’ve worked in digital design since the early web era, across agencies and product teams, designing experiences that are useful, meaningful and human. I’m increasingly exploring the intersection of design, AI and product building.

How I work, according to AI

The recurring pattern

Across Charles' product and generative work, the same method keeps appearing: define the source of truth, specify constraints, compare the result against intent, turn failures into explicit rules, and iterate without disturbing approved work.

What stands out

  • Systems thinking
  • Clear intent
  • Controlled iteration
  • Design systems
  • Edge-case definition
  • Implementation QA
  • Scope discipline
  • Preserves approved work
  • AI collaboration
  • Cross-functional thinking

How he works

Systems over screens

The work is defined as connected behaviour, states and rules rather than isolated screens. Product logic, lifecycle and edge cases are treated as part of the design.

Intent before implementation

Visual truth and functional truth are separated. Figma defines presentation; requirements define behaviour, content and scope. Implementation is reviewed against both.

Controlled scope

Approved work is protected. Changes are deliberately surgical, with explicit instructions about what must not change.

Failures become rules

Bugs and generation errors are treated as evidence of a missing or violated rule, then converted into reusable specifications.

Human-directed AI

AI is used as an implementation and creative collaborator, not the product owner. Intent, judgement and final approval remain human-directed.

Specification as a design skill

The same discipline extends from UX into generative media: assign references, preserve fixed assets, define motion and constraints, then iterate against intent.

The shift

From individual outputs to reliable systems

The work increasingly shifts from producing individual outputs toward designing systems that reliably produce the intended outputs.

What connects the projects

MindLens: behavioural systems and trust

Considered: discovery, content and community mechanics

Portfolio: communication and prioritisation

AI creative work: direction, consistency and controlled generation

Different problems, one consistent method.

Underlying strength

Design specification and controlled iteration.

AI Critique

Strong systems thinking, explicit state and edge-case definition, high sensitivity to implementation drift, and a consistent preference for preserving approved work rather than repeatedly redesigning.

Bottom line

The strongest pattern is not a particular tool or medium. It is the ability to translate intent into constraints, test the result against that intent, and progressively make the system more reliable.
