The product I worked on as ServioAI is now Pairio β€” accepted to YC Spring 2026, live in 4 German manufacturing plants. The two founders, Tim Zinkl and Matthias Wolf, took it through the batch after my departure.

Project Overview

Joined as the first engineering hire on a 3-person team alongside the founders Tim Zinkl and Matthias Wolf. Built the platform across four surfaces β€” FastAPI backend, Next.js web app, Expo mobile app, and a Microsoft Office add-in β€” all in one monorepo. I insisted on being in real customer conversations to keep the AI pieces grounded in actual maintenance workflows, not assumptions.

Worked Oct–Dec 2025, capped off with a full web β†’ mobile port in the final month. Left to focus on my master's thesis at TUM.
