Andreas Herzinger

As a Generative AI Engineer and Full-Stack Developer, I combine academic depth with pragmatic product development. My focus is on transforming state-of-the-art language models (LLMs) into robust, business-critical applications – from intelligent process automation to scalable voice agents.

Research & Expertise

Unlike pure "no-code" developers, I bring profound background knowledge from research. During my work on the "Rankify" framework at the University of Innsbruck (Data Science Group), I delved deeply into Retrieval-Augmented Generation (RAG). I understand not only how to connect APIs but also the mathematical and architectural foundations of modern LLM inference (Chain-of-Thought, ReAct). I also contributed to a research paper that has now been submitted for an ACL conference.

Currently, I develop AI products for startups that deliver real added value. My focus areas are:

Advanced Automation: Development of complex, scalable workflows with n8n (Self-hosted/Cloud).

Conversational AI: Building chatbots and personalized voice agents (via Vapi, Twilio & LLMs) that dynamically access company knowledge.

Software Engineering: Solid full-stack development (Python, Flutter, Java) and database design (SQL/NoSQL) to seamlessly integrate automations into existing IT infrastructures.

I work precisely, standardized, and with the aim of building solutions that are maintainable in the long term.
