What I'm looking for

I’m looking for part-time roles in AI workflow automation and internships in AI/ML or cloud integration and backend development.

Since December 2025, I’ve developed and put AI agents into production using n8n, OpenAI, and REST APIs. My projects include a nutrition assistant that analyzes meals sent by WhatsApp or Telegram, automated restaurant bookings, and a voice receptionist for a physiotherapy practice.

I also developed an MCP server to connect AI agents with external tools, and built a cloud data pipeline for manufacturing data using Microsoft Azure and Azure SQL Database. I’m a Mechatronics student at SRH Hochschule Berlin, combining software development with an engineering background.
