PERFORMANCE MARKETING · GROWTH SYSTEMS · AI AUTOMATION

I drive the numbers — and build the systems that hold them.

Performance-marketing operator with a real track record managing six-figure ad spend to profit — plus the rare half most marketers don't have: I build the automation and AI infrastructure underneath, so growth compounds instead of leaking.

01 CASE STUDIES

Proof, not promises.

GROWTH INSTINCT

Helped lift a UK e-commerce store's monthly sales past $100K.

PROBLEM

Alloy Wheels Direct, a UK e-commerce retailer, had strong traffic — ~4,000 organic visits/day — but converted at ~0.5% vs a ~2% category benchmark. Demand was leaking out the bottom of the funnel.

WHAT I DID

A focused 2-week, in-person growth engagement. Audited the funnel and prioritised fixes by revenue impact. The needle-mover: I identified that introducing free shipping was the single highest-leverage unlock, made the case to the owner, got it approved, and shipped it alongside targeted UI/UX fixes.

RESULT

During my 2-week engagement the store was doing ~$80-90K in monthly sales. The owner later confirmed it had grown past $100K/month — following the free-shipping change I identified and pushed through, plus targeted UX fixes.

PAID PERFORMANCE

Scaled a brand's paid channel to 4.21× ROAS.

PROBLEM

An e-commerce brand needed profitable paid growth on a marketplace where wasted spend destroys margin fast.

WHAT I DID

Built the full campaign architecture and ran ongoing optimisation — keyword research, bid and structure management, tight ACoS control across the catalog.

RESULT

$234,583 in sales on $55,746 spend — 4.21× ROAS at 23.76% ACoS, over 8 months. Verified with a real ad-console screenshot.

SYSTEMS BUILD

Built the system a home-services business runs on — and scaled it ~7×.

PROBLEM

The business was leaking leads after the click — missed calls went nowhere, no follow-up, no review engine. Great at the job, losing money at the front desk.

WHAT I DID

Built an end-to-end CRM + automation stack: missed-call → instant-SMS text-back with intake form, a multi-channel inbox, an AI voice agent for overflow calls, a full job pipeline, and automated review + referral requests on completion.

RESULT

The live GHL dashboard shows it working — AU$21K tracked revenue in a recent 30 days at 72.97% conversion through the funnel I designed. Owner-reported, the business has grown ~7× (from ~$4K to ~$30K/mo) since it went in.

OUTBOUND

Ran cold-email campaigns to 60-80% open rates.

PROBLEM

Most cold outreach dies in the inbox — low-20s% open rates, no replies, wasted lists.

WHAT I DID

Built and ran the campaigns end-to-end — list building and enrichment, domain warmup and deliverability, multi-step sequencing, and copy tuned to the offer.

RESULT

60-80% open rates across several campaigns — 61% on one 173-send sequence — with real replies and booked calls.

03 OPERATOR

The operator behind the results.

I started in e-commerce — building and launching my own product on Amazon, learning paid growth the hard way, on my own money. That turned into managing six-figure ad accounts for other brands, then five-plus years across e-commerce, agencies, and SaaS marketing in three countries.

Today I run ClearScale — building AI-automation and growth systems for businesses — and I run my entire operation on infrastructure I built myself. I've always been an operator first: I build the thing, market it, and keep it running. Now based in Asia, working remotely with teams worldwide.

"We used to get jobs word of mouth — now, since our whole marketing structure was reworked, we get more enquiries than ever, 99% through Google, and we haven't even run paid ads yet. Amazing job, highly recommended 🙌"

05 FAQ
What role am I looking for?+
A growth or marketing operator seat at a startup — head of growth, growth lead, or performance marketing. I run the full stack: paid, SEO, CRO, lifecycle, and the automation underneath. Open to full-time, fractional, or contract-to-hire.
Am I available full-time, and where am I based?+
Yes — remote, full-time. I'm based in Asia (GMT+7) and work comfortably across US and EU hours. Fractional and contract-to-hire also work well.
What's my edge over other operators?+
The combination. I drive real performance — six-figure ad spend to profit, an e-commerce store past $100K/month — and I build the systems that hold growth: CRM, lifecycle, AI agents, and the infrastructure underneath. Most operators do one or the other; I do both.
Can I work with your stack?+
Almost certainly. I run GoHighLevel, Next.js / Vercel, Supabase, N8N, Claude / LangGraph, GA4 / GTM, and the major ad platforms daily — and I pick up new tools fast.
What proof and references can I show?+
The case studies are right here; my portfolio page has every tool and system I've built with a live demo; and I'll share references on request.
How do we start a conversation?+
Book a 15-minute call or email me — a quick chat about the role and whether it's a fit. No pitch, no pressure.
