About Me

Joshua Tesch

I'm a full-stack web developer with 4+ years building production WordPress, headless CMS, and JavaScript applications.

Today I'm the technical owner of a marketing website: architecture, Core Web Vitals, technical SEO, analytics, accessibility, and increasingly the content strategy behind them.

I also build AI tooling that does real work: an MCP server that lets AI assistants manage WordPress, and an autonomous multi-LLM pipeline that audits SEO and AI visibility every week.
