Growth.

Marketing spend shouldn't feel like guesswork. I design, build, fix and wire up the websites, funnels, tracking and automation that turn it into measurable growth — the strategy and the code, from one pair of hands.

01 WHAT I DO CAPABILITIES

The Full Stack Between
a Campaign and a Conversion.

/ 01

Consultation & Audience Strategy

Before a line of code: who your customer actually is. I pin down the demographics, where they live and how to reach them, then map what they want, what they need, and the pain your offer solves — so every build that follows speaks to the right person with the right message.

Marketing Engineering

Full-stack builds done properly: fast front-ends, real back-ends, headless CMS, and the API integrations that hold a modern marketing setup together.

Next.js / ReactNodeHeadlessAPIs
/ 03

Funnels & CRO

Funnel design, A/B testing and conversion-rate optimisation that compounds — so more of the traffic you already pay for turns into revenue.

Targeted Landing Pages

Highly targeted landing pages designed to convert: one audience, one message, one job. Message-matched to the ad, fast to load, and ruthlessly focused on the CTA — built on any platform, or fully custom.

Tracking & Attribution

GA4, server-side tagging, clean event design and dashboards that actually answer the question: which spend is working, and which isn't.

Automation & Martech

CRM, lifecycle email and the Zapier / Make / API glue that runs the repetitive parts of the business automatically — webhooks and custom connections to wire up tools that don't talk to each other out of the box.

Technical SEO & Performance

Core Web Vitals, site architecture and organic growth baked in from the first commit — not bolted on after launch. Plus GEO: structured data and llms.txt so you surface in AI search results, not just Google's.

/ The inheritance

The Webflow site I inherited ran on patchwork — quick fixes layered over quick fixes, to the point where the custom-code workarounds were interfering with the non-technical marketing team's ability to use the site's core functionality at all. And no clear SEO strategy behind it — hundreds of unorganised keywords with no relation to the business, its core offer or its demographic, all needing audited and purged. Foundation first: legacy code untangled, functionality restored, performance stabilised, keyword set audited down to what actually mattered.

/ The rebuild

Sole developer on the full site redesign — partnering with a designer and PM, owning all code, implementation and deployment, with zero SEO drop-off — and working closely with the VP of Marketing and the team copywriter to make sure the site's copy and strategy matched the newly sharpened product positioning. Later led the technical side of the migration to HubSpot alongside a partner agency — every deadline met — and extended the CMS with custom modules: a clean HTML embed, an SEO-optimised FAQ, a Lottie module, and a one-click no-index toggle for easy per-page indexing control.

/ The strategy

Content strategy first: a SEMrush architecture clustering thousands of terms by product and solution, keywords mapped to intent, and direction for the copy team. My own flagship piece — a dropshipping-tariffs guide, conceptualised and executed solo, interactive calculator included — outperformed the homepage for weeks and held top-3 rankings for the year the topic stayed newsworthy. Organic and paid ran as one system — SEO research steering PPC's keyword targeting, and flagging the terms paid no longer needed to buy. Competitive intelligence fed the whole team: competitor breakdowns by product, built into resource sheets — their USPs, social presence, and where they were focusing their efforts.

/ The engine

Underneath it all: a sitewide content overhaul, duplicate-content and cannibalisation fixes, technical SEO, structured data and an llms.txt for AI search — carefully curated in line with the brand and product positioning — multiple new landing pages and lead magnets targeted tightly to specific products and demographics, lead-gen calculators feeding HubSpot with end-to-end UTM tracking, and GA4 flowing into a Looker Studio dashboard I built for the whole marketing team — leads, live ad performance, organic and social trends at a glance, filterable by date — so nobody waits on a report to know what's working. Partnered with RevOps repeatedly to keep automations and forms airtight — and when the cybersecurity audit landed, I was trusted to bring every front-facing property to full compliance, through hands-on fixes and vendor coordination.

/ The payoff

The new site and digital experience lifted website traffic by 50% and inbound opportunities by 45%. Add a 41% lift in organic converted leads in the first year, an enterprise client closed from organic alone — zero outbound — and organic leads and closes that held strong while AI Overviews swallowed everyone else's search traffic. Site health climbed from 67% to 99% in SEMrush's audit — 7 points above the top 10% of sites, 22 above the industry average. Then the quieter wins: a marketing team fluent in the technical standards behind good SEO and AI visibility, duplicate content avoided by habit, a sharper content strategy — and a website the team actually finds easy to use.

04 ABOUT THE APPROACH
David Vaughan — Creative Wavelength

Most marketing problems get misdiagnosed. A strategy gets torn up when the real culprit is a leaky funnel — a build, a tracking setup or an automation quietly bleeding conversions underneath. So I diagnose before I prescribe. Sometimes the funnel needs patching; sometimes the course really does need to change. Guessing is what costs money — a ground-up redesign bought to fix what was actually a messaging problem, or an automation that never got wired in.

/ How I work

The work sits in the gap between marketing and engineering: one person who scopes the campaign, ships the site, instruments the tracking and wires the automation that makes it all run. No juggling three agencies. No six-week handoffs. No pretending to be bigger than I am. Years on lean teams shaped that — wear whatever hat the outcome needs, outgrow the remit without being asked, ship the fix instead of booking another meeting about it. And I've been fully remote since long before Covid made it normal: by choice rather than circumstance, and never treated as a perk.

/ The road here
Thirteen years · every corner

One marriage, two country moves, four region moves and a house. Traditional and performance marketing both, the theory learned as thoroughly as the tools: client ad accounts, print and web design in Photoshop and InDesign (certified), photography, a conversion-rate optimiser stint inside a market research firm, and e-commerce SMEs built and scaled.

Founder — AceFunnels

The four-person funnel agency I founded and ran: webinar funnels drawing accredited investors for US coaching and real-estate brands, and a full e-commerce overhaul for a nutraceuticals company.

In-house — high-growth SaaS

These days I own the web infrastructure of a subscription-commerce platform, custom HubSpot modules and all.

Always sharpening
