Service · Design & Build

Design and build, not just advice.

The short answer

I design and build working software for e-commerce, retail and restaurant brands: clickable prototypes, MVPs and pilots, features in your live product, or design on its own. With agentic AI tools, a senior designer-developer now ships what used to take a small team, and I bring in trusted designers and engineers when a project needs more hands. Every project is scoped and priced up front.

What I build

Why it's faster now

Agentic AI tools turn a clear spec into working code in hours. That changes who can build: one senior person who can design, write the spec, direct the tools and review the result can now deliver what used to need a designer, a front-end developer and a product manager. I've been all three for 15 years, and I build my own sites, apps and an MCP server this way.

It also changes what's worth building. No platform fits every brand, and custom used to be priced for the biggest ones. Now a brand can get software shaped to its own operation and budget, and use off-the-shelf platforms only where the problem really is common.

SaaS products usually get you about 80% of the way to your goal. The last 20% costs you more: custom work billed by the vendor, workarounds your team maintains, features you wait quarters for. That last 20% is often where your advantage is, and it's what I build.

Speed doesn't replace judgment. Every project starts from the problem and a written spec, and nothing reaches production without proper review, testing and accessibility checks.

Who does the work

I lead every project and do much of the design and building myself. When a project needs more hands or a specialist, like native mobile, back-end integration or visual design at scale, I bring in trusted designers and engineers and stay accountable for the result.

How it's priced

Scoped per project: what's being built, for which platforms, and whether it runs in production. Design & Build pairs well with a Digital Audit (decide what to build) or a Fractional Head of Product retainer (lead it over time).

Questions people ask

Can a product consultant also design and build?

I can. I’m a designer, front-end developer and product manager, and with agentic AI tools I design and build working software directly: prototypes, MVPs and pilots, production features, or design on its own. When a project needs more hands, I bring in trusted designers and engineers and lead them.

How much does a design and build project cost?

Each project is scoped and priced after a conversation, based on what’s being built, for which platforms, and whether it has to run in production. Start a conversation →

How do AI tools change what a small team can build?

Agentic tools turn a clear spec into working code in hours instead of weeks, so a senior designer-developer can now ship what used to take a small team. The bottleneck moves to deciding what to build and reviewing it carefully, which is the part I lead. From PRD to prototype with AI →

Is AI-built code safe to ship?

Not without review. Prototypes are for learning. Anything that goes to production gets the same engineering review, testing, accessibility and security checks as any other code, and fits your team’s standards and stack.

Do you replace our agency or engineering team?

Not necessarily. Many clients use me to move fast on prototypes and pilots, then hand proven work to their team or agency. Others have me build features inside their product alongside their engineers.

Not sure where to start?

30 minutes. No deck. Just an honest conversation about where you are and what’s in the way.
