Selected work

2024 - present / Titan Shark Technology Group

InboundSavvy

A website builder and site-audit platform, co-built from the ground up. I own the builder console, the audit engine, authentication, the AI integration and the deployment infrastructure. This site runs on it.

The Console

Drag-and-drop builder with a template library and a static-site generation pipeline. Publishes customer sites to a CDN with domain attachment and SSL handled automatically.

Web Audit

Runs 200+ SEO, performance and accessibility checks against any URL, down to robots.txt, sitemap.xml and CSS, with scheduled monitoring and tiered guest access.

MCP server

Site editing from Claude, ChatGPT, Gemini, Cursor and Copilot. Per-site scoped credentials keep each assistant locked to a single tenant.

Edge architecture

Static output on a CDN with no application server or database in the request path, TLS 1.3 throughout. Removes a class of runtime failure and costs $2.50 per site per month.
