What I'm looking for

I'm looking to build reliable AI/ML and backend products, especially RAG, LLM automation, inference, evaluation, data workflows, and event-driven systems that move prototypes into production.

At Nexi Group, I build backend integrations and SQL data workflows for regulated PayTech systems, improving reliability, data integrity, and automated card lifecycle operations. I've also investigated live payment incidents and delivered fixes across database and service layers.

I'm focused on turning AI ideas into dependable software, from AI-assisted knowledge retrieval that reduced manual lookup effort by an estimated 30–50% to safe GitHub Copilot adoption in regulated development workflows. My interests include ML engineering, RAG, LLM automation, inference services, and evaluation workflows.

Alongside my work at NTUA on EU research projects, I've built Kafka-based integration platforms, AWS document-ingestion systems, and AI-ready SaaS backends. I write about applied AI, cloud architecture, and event-driven systems, and created SpaceSlam to explain real AI engineering to wider audiences.
