Scouting report

SEO-tooling specialist building AI schema/render auditors

assessed from open-source footprint

Mid
54signal

Jose has carved a clear niche in technical-SEO Chrome extensions — an AI-powered schema-markup auditor and an SSR-vs-CSR render auditor — built in JavaScript with Swift and ShaderLab also in the mix. Despite a 16-year-old account, output is light (9 commits last year, 63% of repos abandoned, 1★ max), so this reads as a focused side-pursuit rather than heavy production work. Worth a look for frontend/SEO-adjacent roles.
