Raven's Progressive Matrices — Abstract Visual Reasoning
Python · PyTorch
- Team project attempting to replicate "An Interpretable Neuro-symbolic Model for Raven's
Progressive Matrices Reasoning" (Zhao et al., 2023).
- Reproduced the paper's three-stage neuro-symbolic pipeline — CNN → supervised VAE for
semantic attribute extraction → cognitive-map relational reasoning — reaching 94%
prediction accuracy.

LLM-Powered GDPR Compliance Classifier
Python · SvelteKit · PostgreSQL · Docker · Ollama
- Built a tool that classifies survey questions against the special categories of personal
data defined in Art. 9 GDPR.
- Developed the full stack: SvelteKit/TypeScript frontend and API routes, PostgreSQL schema,
and a three-container Docker Compose deployment. Kubernetes load balancing is planned.
- Ran all LLM inference locally through Ollama so sensitive institute data never leaves the network.

Quick Equipment Log: Hospital Equipment Tracking by Voice
Kotlin · Jetpack Compose · Gemini API · Three.js
- Overnight hackathon with Tallaght University Hospital: replaced the
occupational therapy department's Excel equipment tracker with AI-powered voice logging
from the ward handsets staff already carry. Won Best Use of Technology.
- Android demo app: an LLM turns dictation into a structured bookings via a JSON schema autofills a form: Human in the loop.
- Identified items by the HealthCare21 service stickers already on every piece of equipment, so the solution needs no new hardware.
