What I'm looking for

Remote SEO-only roles: full-time, contract or long-term freelance. Technical, on-page, local and e-commerce SEO plus AI search (GEO). Based in Brazil, available for US working hours.

At Freelance / Self-Employed, I’ve delivered SEO projects across 10+ countries and managed SEO for 200+ websites. For multiple clients in competitive niches, I increased organic traffic by 500%+ in under 90 days.

I develop and execute SEO strategies from technical audits through content campaigns. My work has included securing #1 Google rankings for highly competitive keywords and achieving an average of 93% yearly organic growth across nearly all managed projects.

I use a four-pillar approach: auditing, error correction, page optimization, and content creation. I build white-hat SEO systems for businesses and e-commerce brands, and I’m available for freelance projects and long-term contracts globally.
