What I Build

Real tools solving real problems. Each product is designed, engineered, and shipped to production — not a prototype or a side experiment.

AccessKnight

Live

Scan any site for WCAG accessibility and AI readability — free.

AccessKnight audits any page for both WCAG 2.1 accessibility and AI readability, then hands you one report — with the shared fixes that satisfy screen readers and the AI engines (ChatGPT, Perplexity, Google AI) that now read and cite the web.

Key Features

  • 33 automated WCAG 2.1 checks
  • AI-readability scoring & crawler access checks
  • Copy-paste, code-level fix suggestions
  • Monitoring alerts & auto-scans
  • Export as text, JSON, or PDF
  • White-label reports & API access (Agency)

Reach

Product line

The systems our studio runs on, packaged for freelancers and small agencies.

Where the tools above are built for developers, Reach is built for people running client work: white-label deliverables, delivery systems, and AI-search (GEO) methodology — the same documents and workflows Horizontal Impact uses with its own clients.

About Me

I build products that solve real problems.

I'm a developer who thinks like a product owner. I don't just write code — I design systems, ship SaaS products, and obsess over accessibility because the web should work for everyone. Every project I touch gets the same treatment: production-ready, WCAG compliant, and built to convert.
