Hello!
I help teams ship digital products, websites, web apps, mobile builds and the AI automation that connects them. End-to-end, hands-on, one repo at a time.
/Services
Web apps, marketing sites and internal dashboards built with Next.js, React and Tailwind. Fast, accessible, easy to live with.
LLM-powered systems for triage, summarization and data enrichment, wired into your existing stack, not bolted on.
End-to-end product builds, strategy, design, engineering, ship. Solo and senior, short feedback loops, no handoffs.
n8n and custom pipelines that connect your tools and remove the human glue from internal operations.

Emin Sengül
Co-Founder & CEO · Product Studio at CODE
Gregor ships consistently, without ever needing to be chased. Complex specs become clean, working solutions, on schedule, in scope.
Szattalov Valerio
Founder & CEO · Insivo
With Gregor on the team, I never feel the pace slowing down. He thinks ahead, builds for the long run, and owns the work like a co-founder.
/Who Am I
I design and I build — both, always. Solo on smaller projects, lead engineer on bigger teams. Mobile apps, SaaS platforms, AI ops tools and automation pipelines. Berlin-based, remote across timezones.
