About me
I build products that actually ship. My own apps are live on the App Store and Google Play with paying subscribers, and I run my own AI phone agent and SaaS in production, so I handle the whole stack: app, backend, servers, store releases and everything after launch. What I build: AI voice agents and chatbots (Twilio, OpenAI, Vapi, RAG), iOS and Android apps, SaaS on Next.js with Supabase and Stripe, and n8n or Make automations with custom code where no-code ends. You talk directly to the developer who writes the code. Message me before ordering and I will tell you what fits your budget.... Read more

Have a nice day eU

Feb 2024 - Present • 2 yrs 7 mos

Founder and sole developer of an Austrian software company. I design, build and ship complete products: iOS and Android apps live in the App Store and Google Play with paying subscribers, SaaS platforms on Next.js with Stripe billing, AI voice agents on Twilio and OpenAI, and n8n automations. I run my own servers and handle everything after launch: releases, store reviews, analytics and support. I build the same stack for clients.
