01 About

I build web platforms
end to end.

I'm a senior software engineer with 7+ years building and maintaining enterprise web platforms across frontend, backend, and content-management systems — from architecture through production support.

I've delivered production solutions across modern web stacks, including React, Next.js, Vue, Node, PHP, and headless CMS platforms. Recent work includes NASCAR's fan profile and rewards platform, CMS migrations, authentication systems, mobile content APIs, and an LLM-powered product demo at AlphaSense.

I focus on building reliable, scalable experiences through thoughtful architecture, clear integrations, strong testing practices, and the performance, accessibility, and usability standards that make products successful.

Beyond engineering, I help businesses improve how their websites perform across modern search experiences. My consulting work combines technical SEO, Core Web Vitals, structured data, accessibility, content architecture, and AI Search Readiness to create websites that are faster, easier to understand, and better positioned to be discovered through both traditional search and emerging AI-powered search experiences.
