About
Hi, I’m Adelina Grebencea, a motivated student passionate about data and AI. I enjoy turning messy datasets into actionable insights and building end-to-end ML pipelines, from data preprocessing to model evaluation and lightweight deployment. I thrive in collaborative environments and love learning new technologies.
Currently pursuing a B.Sc in Computer Science and an M.Sc in Big Data, Data Science, Analytics and Technologies, I have hands-on experience with Python, SQL, Power BI, ETL, and REST APIs through academic projects and freelance work, including an AI-powered Smart Invoice Analytics System that automates data extraction and anomaly detection.

Work experience
Led an AI-driven pipeline for automated data extraction from invoices using GPT-4o, with data validation, normalization, and a fraud/anomaly detection component (Isolation Forest) plus predictive modeling (Random Forest). Built an automated EDA module to visualize spending patterns, seasonality, and top-vendor statistics.
Smart Invoice Analytics System: Automated Data Extraction & Intelligent OCR using OpenAI GPT-4o to extract structured data (client details, line items, VAT) from unstructured invoice images; Data Engineering: validation framework to sanitize inputs and normalize formats; ML & Analytics: applied scikit-learn algorithms including Isolation Forest for anomaly detection and Random Forest for predictive modeling of cost drivers; BI: automated EDA module to visualize spending patterns, seasonality, and top-vendor statistics.
Power BI projects: Preprocessing datasets, data cleaning, transformation with Power Query, data modeling (relationships), and dashboard/report design to support data-driven decisions (07/2025 to 11/2025).
