Hi, I'm Marcus
Full-stack developer with 9 years of building websites across every platform imaginable. I built VitalSite to fold everything I learned into a single tool — so the problems that show up on every project get caught in one scan.
Nine years, every platform, one recurring problem
Over nine years I've built and shipped 95+ websites — on WordPress, Shopify, Wix, Webflow, custom React stacks, and everything in between — and wired them into CRMs and automation platforms to run real businesses.
Across all of them, the same issues kept surfacing at the end of every project: missing security headers, broken SEO and structured data, accessibility gaps that exclude real users, and no single place to see it all. Every launch meant stitching together three or four separate tools, each with its own dashboard and its own blind spots.
So I decided to take everything I'd learned — across every platform and CRM I'd touched — and put it into one product. VitalSite is the tool I wish I'd had on every project: it scans your whole domain for security, visibility, and accessibility in a single pass and hands back one prioritized, AI-written fix list.
A full-stack toolkit
Front-end
React, Vue, and vanilla JS — accessible, responsive interfaces that feel fast.
Back-end
Node, REST & SSE APIs, Postgres/Prisma, auth, payments, and background jobs.
Platforms & CMS
WordPress, Shopify, Wix, Webflow, and fully custom stacks — I have shipped on all of them.
CRM & automation
HubSpot, Salesforce, and bespoke CRM builds wired into real business workflows.
Security & SEO
Hardening, headers, Core Web Vitals, structured data, and AI/GEO visibility.
AI engineering
LLM-powered features, fix generation, and answer-engine optimization.
Solve the whole website — not one slice of it
Most tools check one thing. Real websites break in three directions at once. VitalSite exists to close that gap: one scan, three pillars, exact fixes — so anyone, technical or not, can ship a site that's secure, discoverable, and usable by everyone.
