I helped a Tunisian e-commerce brand scale Meta Ads performance from December 2024 to March 2025 by improving creative performance, budget allocation, and campaign optimization. Results: • Purchases: 275 → 626 (+128%) • CPA: €10.66 → €7.91 (-26%) • Ad Spend: €2,933 → €4,952 (+69%) • Revenue: €15K → €355K The key win was scaling purchase volume while reducing acquisition cost. My approach: identify winning creatives, shift budget toward what works, and optimize continuously based on performance data.
