Reliable data isn't just a nice-to-have. It's the foundation everything else gets built on. Bad inputs mean bad decisions, wasted hours, and tools that can't do their job properly.
This matters even more now: AI systems are only as good as the data and context they're fed, so clean, well-structured data has become more valuable than ever. Across every project, my goal is the same: to provide data your team can trust without double-checking.

Martim N.
Senior Media Buyer | Meta Ads, TikTok Ads | eCommerce Specialist
Lisbon, Portugal
$25/hr$25 per hour5.0 (24) 32 jobs $40K+ total earnings
Scaling eCommerce Brands with Meta Ads & TikTok Ads — $50M+ in Managed Spend
🎯 $50,000,000+ in lifetime ad spend managed across Meta Ads and TikTok Ads
🎯 ~$700,000/month in active client spend right now
🎯 100% focused on eCommerce: DTC brands, Shopify stores, and 7–8 figure operators
❓ Spending serious money on Meta and TikTok but ROAS keeps slipping as you scale?
❓ Stuck at a revenue ceiling you can't break through, no matter how much you test?
❓ Tired of media buyers who treat your ad account like a $1K/day experiment instead of a real business?
I'm a Senior Media Buyer specialized in eCommerce. Over the past years I've deployed more than $50M in ad spend across Meta and TikTok, currently managing around $500K per month for DTC and Shopify brands scaling past 6, 7, and 8 figures.
I don't run "boosted posts." I build paid acquisition systems that scale profitably — and stay profitable.
◆ RESULTS I'VE DELIVERED FOR eCOMMERCE BRANDS
✅ Scaled DTC brands from $50K/month to $700K+/month in revenue through Meta Ads
✅ Took Shopify stores from 1.8x to 4.5x+ blended ROAS without killing volume
✅ Reduced CAC by 30–50% across multiple accounts in the first 60 days
✅ Launched and scaled new product lines from $0 to $100K+/month in under 90 days
✅ Recovered underperforming accounts spending $50K+/month back to profitability
✅ Built TikTok Ads from a "testing channel" into a primary acquisition engine for multiple brands
◆ WHY eCOMMERCE BRANDS HIRE ME
Most media buyers fail because they optimize the wrong layer. They tweak audiences, restart campaigns, blame the algorithm — and ignore the structural reasons why the account isn't scaling.
I look at the full picture before touching a single campaign:
☑️ Offer strength, pricing, and AOV math
☑️ Creative angles, hooks, and rate of fatigue
☑️ Account structure and learning phase stability
☑️ Meta Pixel + Conversions API (CAPI) accuracy
☑️ TikTok Pixel + Events API setup
☑️ Attribution gaps between platform data and Shopify
☑️ Product feed health and catalog optimization
☑️ Realistic budget vs. profitability curve
Only then do we scale — with data, not guesses.
◆ WHAT I DO
🛒 Meta Ads for eCommerce — Advantage+ Shopping, ASC, manual campaigns, DPA retargeting, full-funnel scaling
📱 TikTok Ads for eCommerce — Spark Ads, creative testing frameworks, Smart+ campaigns, profitable scaling past $10K/day
🎨 Creative Strategy — Hooks, angles, UGC briefs, ad concept development, creative testing systems
📊 Tracking & Attribution — Meta CAPI, TikTok Events API, GTM, server-side tracking, Triple Whale / Northbeam setup
🛍️ Catalog & Feed Management — Shopify feed optimization, DPA, catalog ads
📈 Scaling Systems — Structured testing → validation → scaling frameworks built for stability, not spikes
🔍 Account Audits — Deep audits for brands spending $30K+/month that aren't hitting targets
◆ WHO I WORK BEST WITH
🔹 DTC and eCommerce brands doing $50K+/month in revenue
🔹 Shopify stores ready to scale past their current ceiling
🔹 Founders and CMOs who want a long-term media buying partner, not a quick fix
🔹 Brands spending (or ready to spend) $30K+/month on paid ads
🔹 Operators thinking in quarters and years, not weeks
◆ HOW I WORK
I treat your ad account like my own money is in it. That means daily monitoring, weekly strategy reviews, transparent reporting on the metrics that actually matter (blended ROAS, CAC, contribution margin, MER) — not vanity numbers.
I'm not the cheapest media buyer on Upwork, and I'm not trying to be. I work with a limited number of brands at a time because $50M+ in spend taught me that focus is what drives outcomes.
If your brand is doing real revenue and you're ready to scale Meta and TikTok properly, send me a message 😉
