Carlos Alberto Cardona B. · Resume

Summary

Technical SEO consultant who verifies every finding against production before reporting it. I rebuilt what Google was receiving from a React app (HTML per route, a Cloudflare Worker with real 301s and 404s, 19 checks before every publish) and daily impressions went from single digits to dozens in two months. I designed Cayu, an SEO research and audit tool generated with Claude Code and tested like an instrument. I come from quality control and medical interpreting: I work well where a mistake has consequences.

What I do

• · Technical SEO audits: crawling, indexing, JavaScript rendering
• · Domain migrations, DNS, 301 redirects and real 404s
• · Prerender / SSG for React, Base44 and AI builders
• · Structured data (JSON-LD) with parity against visible content; AEO and GEO
• · Search Console and GA4 read with two instruments
• · Cloudflare Workers, sitemaps, robots.txt, Open Graph, hreflang
• · Keyword research with real volume and difficulty calculated from the top 10
• · Automation with Claude Code and MCP servers; QA with two inputs that differ

Case studies with evidence (cardonaseo.com/en/portfolio)

• A single page application that Google received empty

  Problem: The site looked complete in the browser, but Googlebot received a title and an empty container.

  What I did: Real HTML per route, a Worker in front with real 301s and 404s, and 19 checks before every publish.

  Result (Sep 17, 2026): Daily impressions on Google went from single digits in July to between 30 and 66 in September.

• Putting cardonaseo.com into production without relying on the dashboard

  Problem: The domain didn't resolve, the platform served crawlers a 350-word template and the sitemap listed noindex pages.

  What I did: DNS on Cloudflare, a Worker as custom domain, my own prerender, real 301s and 404s, authoritative sitemap and llms.txt.

  Result (Sep 19, 2026): 9,820 requests served in five days with 0 errors, and the audit's 7 discrepancies published with their status.

• Cayu, the SEO tool I designed and verify

  Problem: Commercial tools gave numbers without a formula: difficulty 0 on a keyword whose top 10 had an average authority of 46.

  What I did: Four MCP servers in Python and a React app, generated with Claude Code under my specification and tested with two inputs that differ.

  Result (Sep 17, 2026): Three times it showed commercial difficulty was underestimating, two of its own defects found and fixed, and 0.18 USD for 31 keywords in two countries.

• How I decided what to sell with data, not intuition

  Problem: I was going to advertise as an SEO auditor. The biggest search was «agencia seo bogota», and I'm not an agency.

  What I did: I measured volumes in four countries, cross-checked two sources where I could and calculated difficulty from the real top 10, in Spanish and in English.

  Result (Sep 17, 2026): Positioning decided: technical SEO consultant. Four days after indexing, the home page already ranks 1 for my name; the rest gets measured in October.

How I work with AI

I use Claude Code connected to the repository every day. I don't hand-write the code: I specify it, generate it, test it with two inputs that differ and verify it in production before calling it done. What I don't master yet: WordPress and Webflow are not my main platforms.
