I build, launch, and optimize e-commerce stores for small and medium-sized businesses, while managing Meta Ads campaigns focused on sales, customer acquisition, and WhatsApp conversations.

For SIFRA, I optimized the existing store and managed Meta Ads campaigns. From April to July 2026, online-store revenue rose from R$16.8K to R$33K while ad spend increased by 8%; online purchases rose from 45 to 74, and ROAS improved from approximately 3.9x to 7.1x.

For CASA DO HANDMADE, I built and continue to manage its Nuvemshop store, including product catalog updates and promotional campaigns. In May 2026, campaigns generated 47 online purchases and approximately R$4.4K in revenue on R$890 in ad spend, while customer-acquisition campaigns generated approximately 30–40 WhatsApp conversations per day.

I also built and launched ZIG ZAG’s Nuvemshop store and supported its launch with initial Meta Ads campaigns. I’m continuing to develop my practical expertise in Google Ads, Google Analytics, tracking, and e-commerce marketing.
