@eliasaravantinos
AI/ML Analyst specializing in econometrics, forecasting, and clear AI-assisted research writing.
GreeceWhat I'm looking for
I’m an AI/ML Analyst with 20+ years of experience in research, writing, predictive modeling, and ICT strategy. I specialize in turning complex digital-economy and forecasting material into structured, high-clarity narratives.
In my work, I combine machine learning and econometrics with prompt-based AI training. I generate and refine analytical content, evaluate AI-assisted outputs for reasoning gaps, and apply consistent quality standards—using approaches such as CatBoost and hierarchical models.
I also develop and teach AI/BI education for public managers. I design prompting, predictive modeling, and reasoning evaluation modules, create structured prompts and scenario-based tasks, and review participant outputs against clear qualitative benchmarks.
Earlier, I authored market and technical reports with a focus on accuracy and readable operator strategy briefs, synthesizing multi-domain inputs into actionable insights. I’ve also built analytical tools, dashboards, and decision support reports, and I’m comfortable working with iterative guidelines in remote, asynchronous environments.
