How it works

From first message to shipped results.

No drawn-out onboarding. We move at the speed the work deserves.

Tell me the goal

A quick call or message. Whether it's lower CAC, a rebuilt funnel, or a piece of software you need shipped — we get specific about the outcome and the timeline.

I audit & plan

Within a business day you get a clear read on what's leaking, what to build, and the fastest path to results — no fluff, no 40-slide deck.

I build & scale

Strategy, execution and the system in between — shipped in the same sprint and optimised weekly against pipeline, not vanity metrics.

Selected results

The work speaks in numbers.

A cross-section — healthcare paid media, lead generation, and a full software build — because the range is the point.

Before you reach out

Good questions, straight answers.

Paid media and growth (Google, Meta, LinkedIn, YouTube), social and content, SEO/GEO, CRO, and full-stack builds — websites, landing-page systems, dashboards and CRMs. Most engagements combine a few of these, because the whole point is that one person can own them together.

Any of them. I'll consider a senior full-time role for the right team, work fractionally as a growth lead, or take on a defined project. What matters is clear ownership and fast shipping.

I direct agentic AI (Claude, Codex) to build production software end-to-end. This site, a full agency website and a working CRM were all shipped that way — front end and backend. You get a marketer who can also deliver the product, without a dev queue.

Remote, working with brands, founders and teams across the US, UK and Europe. I keep overlapping hours for calls and launches and stay reachable through the work.

Let's build something
