I'm a Technical SEO Specialist with hands-on experience managing SEO across international B2B websites, including enterprise multi-domain ecosystems with 2,500+ URLs. In my current contract role, I lead technical audits, support large-scale site migrations, implement schema and hreflang, and develop AI-optimized content strategies. One migration I supported resulted in +120% organic clicks and +210% impressions within 28 days. I work daily with Google Search Console, GA4, Ahrefs, SEMrush, and Screaming Frog, and I have growing expertise in GEO/AEO — optimizing content for AI-generated search results across ChatGPT, Perplexity, and Google AI Overviews. Beyond the technical side, I enjoy explaining complex SEO concepts in plain language and helping teams build confidence in their own SEO decision-making. I'm comfortable working remotely, communicating across time zones, and providing actionable feedback that teams can actually implement. I'm based in Colombia (ET-friendly timezone) and available for remote mentorship engagements.…I'm a Technical SEO Specialist with hands-on experience managing SEO across international B2B websites, including enterprise multi-domain ecosystems with 2,500+ URLs.
