AI side projects

In my spare time, I apply AI to problems that carry personal and societal weight. If you're interested in contributing, feel free to drop me a line.

  • Pyxida

    health · cardiology · 2026

    A personal companion that helps adults with congenital heart disease (CHD) navigate lifelong care with confidence and clarity. It brings a patient's multi-year medical history and care into one coherent, longitudinal picture, and provides appointment preparation and personalized physical-activity guidance.

  • FindMyHeart

    health · metabolic · 2026

    A cardiometabolic companion built for what generic fitness apps miss. It synthesizes your medical records and medication profile with real-time wearable data, delivering clinically contextualized feedback and personalized lifestyle interventions. Developed during LifeHack Athens 2026, a 36-hour life sciences hackathon at the heart of Panathēnea.

  • birdii

    news · llms · 2025

    An AI-native news app that redefines how we engage with news. Instead of static headlines, birdii turns each article into something you can interact: summaries, additional background information for unfamiliar topics, and a conversational Q&A that lets you ask follow-up questions and dig as deep as you want.
