I conceive, design and build software from first premise to production.
I work with founders and design-led teams on new products, prototypes, and the systems beneath them. My work moves between product strategy, interaction design, engineering, and the operating loops that turn a promising prototype into a durable product.
I am based in London and interested in senior product engineering, prototyping, and design-technology leadership roles.
- Siteinspire — an independent design reference platform I have conceived, designed, engineered, edited, and operated from day one.
- Material intelligence — a connected body of private product, interface, graph, and evaluation work for making material knowledge usable. Public details are deliberately limited.
- Product creation and prototyping — shipped products, native applications, editorial systems, and decision instruments spanning early premise, interaction design, implementation, and handoff.
The fuller product story, including public and access-controlled case studies, lives on my portfolio.
- AgentSurface — a practical standard, scorecard, and transformation toolkit for making software useful to agents.
- Arc — a disciplined workflow layer for taking agentic software work from premise through implementation, review, testing, and release.
- WireText — an editable, text-native wireframing system: Figma, but everything is text.
- Patternmode — focused React interaction patterns designed to survive real product constraints.
- Motif — image-generation tooling built around repeatable, inspectable creative workflows.
- Envelope gives local coding-agent CLIs typed Zod inputs and outputs.
- @howells/ai provides one typed TypeScript contract across model providers while preserving escape hatches.
GitHub is the working catalog; the portfolio is the edited argument.
