Applied ML in production.
I build systems that work in production — and propose the tools teams don't know they need yet. Deep-learning classification, computer vision, agentic RAG, ERP systems.

Act I · The Context
The ERP
A full-stack ERP for the Greek agricultural sector — supporting 10k+ farmer clients with declarations, subsidies, land registry, and compliance reporting.
Act II · My Proposal
Crop classification
from satellites.
MSc thesis: ConvLSTM + Conv3D models on Sentinel-2 multispectral time-series to classify crops — and automatically flag declarations that don't match the satellite.
The proposal: The ERP handles declarations, but can't verify them. I proposed using satellite imagery — the same data OPEKEPE uses for aerial checks — to classify crop types automatically and surface inconsistencies before they become penalties.

Timesteps
Sentinel-2 patches per season
Models trained on the PASTIS benchmark (France) and validated on Greek region patches. Architecture: ConvLSTM encoder + 3D convolutional decoder, pixel-level classification.
Act III · My Proposal
Advisory RAG
for the team.
A LangGraph agentic RAG system that answers Greek agricultural regulation questions with citations — built so advisors don't have to memorize 200-page policy documents.
The proposal: Advisors spent hours per week hunting through OPEKEPE bulletins and CAP regulation updates. I proposed a retrieval system that indexes the authoritative sources and answers questions with source citations — reducing a 20-minute search to a 10-second query.

Τι είναι το ΟΣΔΕ και ποιον σκοπό εξυπηρετεί;
Το ΟΣΔΕ (Ολοκληρωμένο Σύστημα Διαχείρισης και Ελέγχου) είναι το πληροφοριακό σύστημα μέσω του οποίου ο ΟΠΕΚΕΠΕ παραλαμβάνει την Ενιαία Αίτηση Ενίσχυσης (ΕΑΕ), διενεργεί ελέγχους επιλεξιμότητας στα αγροτεμάχια και καταβάλλει τις άμεσες ενισχύσεις της ΚΑΠ προς τους δικαιούχους αγρότες.
