Your ads are only as good as the data feeding them. I fix the data.
I'm a GA4/GTM tracking engineer with a developer background: 115 Upwork projects, 6,000+ hours, Top Rated Plus. I build and repair the tracking layer that decides whether your ad budget scales or burns: GA4, Google Tag Manager, server-side GTM, Consent Mode v2, Meta CAPI, and Google Ads conversions.
Results clients paid for and kept:
- Recovered 15-40% of conversions lost to Consent Mode misconfiguration
- Cut GA4 event duplication by up to 60% with clean dataLayer architecture
- Raised attribution accuracy with server-side conversion APIs for Google, Meta, LinkedIn, and Reddit
- Turned hours of manual reporting into minutes with Looker Studio dashboards teams actually open
What I handle end to end:
- GA4 + GTM: events, ecommerce funnels, custom dimensions, cross-domain tracking
- Google Ads conversion tracking and enhanced conversions
- Meta Pixel + Conversion API with deduplication and event-quality checks
- Consent Mode v2 and GDPR/CMP setups: Cookiebot, OneTrust, custom banners
- Server-side GTM for cleaner data and stronger attribution
- Shopify, WooCommerce, WordPress, Webflow, Framer, and custom JavaScript tracking
- Looker Studio dashboards your team can actually use
Why me and not another GTM freelancer: most can click together basic tags. I read source code, inspect the dataLayer, and debug JavaScript - so the tracking I build survives redesigns, plugin updates, and CMS migrations instead of breaking a month later.
Top Rated Plus | $100K+ earned | 6,000+ hours | 115 jobs completed
How we start: send me your site, ad platforms, and tracking goal. I will map your funnel and tell you exactly what is broken, what is missing, and what it takes to fix it - before you commit to anything.

SERVER-SIDE TRACKING, (also) RESTRICTED-INDUSTRY ADS & PERFORMANCE MARKETING and AI automations - the work most agencies can't quote on.
I scale paid acquisition for brands that break standard agency templates: regulated verticals, broken tracking, signal loss, account-ban risk. If Google and Meta keep shutting your competitors off - or your data's been wrong since iOS 14 - that's exactly where I work.
15+ years in Google Ads, (12+) Meta Ads, GA4, GTM and server-side tracking. Former CTO of a UK marketing agency. ISTQB Certified. I've supported accounts running $1M+/month in ad spend, and I recently scaled a new store from $0 to $200k/month in revenue in 6 months.
โญ "Incredible scaling of ad spend while maintaining ROAS. Tracking and attribution implementation top notch." - verifiedpeptides (Regulated ยท Peptides, Upwork-verified)
WHERE I'M THE SPECIALIST MOST CAN'T REPLACE:
๐ฏ SERVER-SIDE TRACKING & ATTRIBUTION - sGTM, Meta CAPI, GA4, Enhanced Conversions, event deduplication, no-cookie attribution. Built to survive iOS, signal loss, ad blockers and restricted-account conditions. (from $3,500 ยท complex/restricted from $6,000)
๐ฏ RESTRICTED VERTICALS - Supplements, CBD, Peptides, Healthcare, ED, Legal. Compliance architecture, multi-account risk isolation, proactive ban management, policy-aware creative. The work that keeps you live and scaling when competitors get banned. (setup from $5,000 ยท management from $6,000/mo per channel)
๐ฏ GOOGLE & META PERFORMANCE MANAGEMENT - full campaign management, bid and budget optimization, weekly reporting. Generic e-commerce/lead-gen from $5,000/mo per channel; Growth single-channel start from $3,500/mo.
๐ฏ 0 TO HERO (3-month programme) - launch or relaunch paid ads with a working system, clean data and a documented playbook. Tracking included. ($5,000 flat)
๐ฏ AI AUTOMATION - Make, n8n, Zapier, custom AI agents and API integrations that kill manual work in reporting, lead routing, QA and ops, increase sales and decrease lost leads.
๐ฏ FRACTIONAL CMO/CTO - senior marketing or technical leadership on retainer for brands that need an operating layer, not just campaigns. (from $12,000/mo)
WHO THIS IS FOR: brands spending $10k+/month on ads ($3k+ for project work) who are scaling past template agencies, running regulated, or losing revenue to broken tracking.
WHO IT'S NOT FOR: under $3k/month spend, social content/community management, web design, or accounts I can't understand within 48 hours - I don't take work I can't do properly. For starting clients I offer 0 to hero 3 months fixed rate plan. After initial consultation to understand if we are good match.
I connect ads, data, tracking and AI into one system. Better tracking โ better data โ better decisions โ faster scaling. Most freelancers do one piece. I do the whole stack.
โโโโโโโโโโโโโโโโโโโโโโโโโโโ
๐ LET'S TALK โ TWO WAYS TO START:
1๏ธโฃ BOOK A $5 USD 15 MINUTE CONSULTATION - bring your situation, I'll bring the diagnostic. I'll flag the 1โ2 biggest leaks I can see and we'll agree honestly whether it's a fit. Message me "CALL" and I'll send the link.
2๏ธโฃ BUY THE $75 or $150 consultation (on my profile) - the fastest way to get me on a call and start the conversation. Simply go to my profile and book a call. Please read description of consultation and choose right one (30 min could be not enough of time on first meeting).
Don't let broken tracking and template agencies cap your growth. Send me a message, book a consultation call or grab the $5 project now - these spots fill fast.

Google Ads, LinkedIn and Meta specialist with 14+ years managing budgets from $2K to $3.5M+ across global brands (Shell, Land Rover), B2B SaaS (ChannelAdvisor, Yoco), and international education (50+ markets). I don't just run campaigns - I build the data infrastructure around them: attribution models, GA4 and CRM setups, lead quality frameworks, and dashboards that connect spend to pipeline and revenue. If your ads are performing but you can't explain why โ or your data and your results don't tell the same story - that's where I work.
I've cut CPA by 75% and grown qualified leads by 40%+ YoY โ for budgets big and small, from lean startups to $3.5M/year enterprise accounts
I help B2B and e-commerce companies turn paid media into a predictable revenue engine โ whether you're spending $2K or $200K a month. Over 14 years, I've run performance marketing at both enterprise scale and hands-on, growth-stage level, and I bring the same rigor to every account regardless of size.
Results I've delivered:
โข 500% increase in sales through digital channels at a global EdTech brand
โข 75% reduction in CPA within 12 months of taking over global paid media
โข 175% conversion rate uplift through landing page and UX optimization
โข 40K+ qualified leads/year across 25 countries and 4 regions (NOAM, LATAM, EMEA, APAC)
โข 40%+ YoY lead generation growth across Paid Media, SEO, and Affiliate
โข Quality Score improvements from 2 โ 9 on underperforming Google Ads accounts
โข $200K+ in cost savings through marketing process simplification
Where this comes from: As Head of Performance Marketing at Education First / Hult International Business School, I managed a $3.5M+ annual ad budget across 25 countries. More recently at Shell, I led global digital marketing across 12 markets, delivering a 175% conversion rate uplift through UX and performance optimization.
Platforms:
Google Ads (Search, Display, Shopping, PMax, YouTube) โข Meta Ads โข LinkedIn Ads (B2B/ABM) โข Bing, Yahoo, Yandex, Baidu, Naver โข Amazon Ads โข Affiliate
Networks
Industries: EdTech/Higher Ed โข SaaS B2B โข Enterprise E-commerce โข Energy โข Finance
Beyond campaign management:
โข CRM & marketing automation (Pardot, Marketo) โ lead nurturing, pipeline tracking
โข Full-funnel analytics & ROI dashboards โ real attribution, not vanity metrics
โข Team & agency/vendor management
I offer flexible monthly retainer packages (Starter / Growth / Premium) so you get senior-level strategy without the overhead of a full in-house hire. Both agency-side and senior in-house experience mean I align campaigns with real business targets โ not just ad account KPIs.

โ Member of 32 Upwork Talent Cloud groups (Enterprise Professionals, Microsoft UTC, Netflix Print Production, Unilever, Tata Communications, Holland & Barrett, Janus Henderson, and others)
โ AI-powered audit and automation capabilities (MCP + RAG architecture)
