I help companies find where AI actually pays off.
Then I build it with them until their team runs it on their own.
About
I'm Mussie, a Berlin-based web developer and growth engineer. For 15 years I have worked between marketing and engineering: I design the funnel, build the site, and wire up the data behind it.
Strategy, code, data, and AI in one person, so nothing gets lost in a handover. Sites in Next.js, automations in n8n, apps on Supabase, agents on OpenAI and Anthropic. You own everything I build.
