What I'm looking for

I'm open to contract, part-time, retainer and white-label work.

At Common Thread Collective, I created Shopify landing pages and static and motion ad creative for 50+ DTC brands in the 7–8 figure range. I matched the creative to each landing page, with builds installed and QA'd in each brand's Shopify theme.

As a freelancer, I make static and motion ads from brands' product photos and reviews, with hook variations for creative testing. I also build mobile-first Shopify pages, funnels and tracking for paid social traffic and A/B tests.

At Grupo PDC – Pediatra de Consultório, I built landing pages, registration funnels and conversion dashboards, and developed a pediatric EMR platform as the sole developer. It serves thousands of pediatricians and 1.5M+ children, with zero critical findings in a third-party penetration test. At CicloInvest, I built internal platforms and revenue products that cut manual workflows from 4 hours to 5 minutes.
