Specialist Profile

Valentin Adrian Rotaru

I am Valentin Adrian Rotaru, an AI integration and automation specialist based in Germany. My experience starts in entrepreneurship and digital marketing and continues with projects in AI agents, document search systems and self-hosted infrastructure. I connect what a team needs with the technical components that can support that process.

Trajectory & Methods

Background & Technical Focus

I started in entrepreneurship and digital marketing, working with email infrastructure, data and recurring processes. As I deepened automation and AI, I built my own environments to test the connections between models, documents and tools. Today I focus on integrating AI into concrete processes: what information an assistant receives, which tools it may use, and how a person verifies the result. My projects include systems with local models, document search, n8n workflows and agent specifications. I complement my experience with continuing education in AI engineering, LLMOps, security, leadership and finance.
