Freelance · Performance Marketer · Based in Belgium

I grow e-commerce brands and build the machines that scale them.

I'm Mert. I take fashion brands from a blank Shopify store to thousands of real orders with Meta and TikTok ads, and I build the software behind it: profit tracking, automatic scaling and AI agents that work while I sleep.

Numbers from the till, not from the ad platform.

Revenue I drove as a freelance performance marketer: Merra (July – December 2025) and Merravè (July – October 2026). Merravè figures come from real Shopify orders, with test and cancelled orders filtered out.

Merra

Jul 2025 – Dec 2025 · First client, the brand that became Merravè

Where it started. I joined a new fashion store as its performance marketer, ran paid social on Meta and TikTok, and helped grow it past six figures in revenue before the brand was rebuilt as Merravè.

€100K+revenue
1,300+sales on Meta & TikTok

  • Built the store, the product range and the offers from scratch
  • Scaled a seasonal coat to 563 sales on Meta in winter 2025, at about €24 per sale
  • Learned which creatives sell: one ad alone drove 395 sales
  • The lessons became the playbook and the tooling behind Merravè

Merravè

2026 – present · Brand, store, paid social, operations

A women's fashion label around one idea: clothes two sisters would actually wear. I helped build the brand and the store, find the products, and I run every euro of advertising on Meta and TikTok.

Bonny & Rose

2026 – present · Brand from zero, store, catalogue, launch

A second brand for a different woman: American, 40+, timeless and comfortable. Built from a blank page in weeks, from the name and identity to a full catalogue and the first campaigns.

  • Name, logo, navy identity and a brand story with two sisters from New York
  • Shopify store with its own product page standard, size charts and offers
  • AI research pipeline that analysed 30 competitor brands to pick the catalogue
  • Launched on Meta in the US with structured product tests

Shopdeck

2026 – present · The operating system behind the brands I work with

Ad platforms tell you what they want you to hear. So I built my own platform that counts profit against real orders, and lets the money follow the winners automatically. Now also used by another e-commerce brand.

  • Real profit per campaign, product and day: Shopify orders joined with Meta and TikTok spend
  • Autoscale: winners get +20% a night on real profit, and roll back after two loss days
  • WhatsApp alerts every 20 minutes for campaigns that burn money, plus a live visitor tracker
  • A 24/7 server with AI agents for research, product photos, reporting and campaign drafts

About

Marketer with an engineer's toolbox.

I spent six years in IT support and full-stack development before I started building brands. That background is my unfair advantage: when tracking breaks, data doesn't add up or a process eats hours, I fix it myself, in code.

Today I work as a freelance performance marketer for fashion brands, end to end: product research, brand and store, creatives and ad copy, paid social on Meta and TikTok, and the numbers behind it. I judge every campaign on real sales and real profit, not on what an ad platform claims.

I'm studying Digital Marketing at SyntraPXL alongside it, and I speak Dutch, English and Turkish.

Profit first

Break-even per product, cost per real sale, and budgets that follow the till.

↯

Test fast, kill faster

Fixed rules for stopping, keeping and scaling, so no money waits on a hunch.

⚙

Automate the boring

Scripts and AI agents do the repetitive work, so the time goes to decisions.

Process

From idea to scaling winner.

The same loop for every product and every brand.

Research

Find what already sells: competitor ad libraries, TikTok Shop data and long-running ads.

Build

Product page, photos, offer and pricing, ready for mobile shoppers.

Test

Several hooks and creatives against one product, one broad audience, fixed budget.

Judge

Cost per real order against break-even, after a full day, never on platform numbers.

Scale

Winners get more budget automatically; fatigue gets fresh creatives.
