I am a Headless CMS developer specializing in Sanity CMS, Prismic, Strapi, Dato CMS, and Ghost CMS, integrated with Next.js and React frontends. Alongside development, I focus heavily on website optimization, technical SEO, and the newer disciplines of AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization), building sites that perform well in traditional search and are structured to surface correctly in AI-driven answer engines like ChatGPT, Perplexity, and Google's AI Overviews. My recent work includes maintaining and scaling Sanity CMS implementations, building reusable component libraries from Figma designs, and improving page performance from the 30s to 80+ scores through technical SEO fixes like structured data, semantic HTML, crawlability improvements, and Core Web Vitals optimization. I work directly with marketing teams and CROs, handling issues independently without requiring constant handholding. My core skills include Headless CMS setup and migration, custom component development, Sanity Studio customization, Prismic Slice Machine, Strapi API development, and Next.js integration, paired with technical SEO audits, schema markup, and content structuring built to perform well across both search engines and AI answer engines. I am also experienced with headless commerce setups using BigCommerce, WooCommerce, and Shopify.
