Hey, I'm Marvin

I help brands get found, get read, and get results.

SEO strategy, editorial copy, and AI prompt engineering. Currently leading search at Britt Creative Co. and content at DNA Magazine Australia.

Three things, done right

Every brand needs to be findable, readable, and persuasive. I make sure all three are covered.

SEO Strategy

Technical audits, keyword research, on-page optimization, local SEO, and AI search visibility (GEO/AEO). I make Google and AI assistants work for you.

Copywriting

Blog articles, landing pages, ad copy, email campaigns, and editorial features. Written for people, optimized for search engines.

AI Prompt Engineering

Custom GPT systems, AI workflow automation, and prompt optimization frameworks. I build tools that make AI actually useful for marketing teams.
