George Paraschos · open to internships and collaborations
Backends that stay honest under load.
Software engineer in Athens, Greece, finishing a degree in Information & Communication Systems Engineering. I care about concurrency that’s actually correct, APIs that fail loudly, and systems that don’t promise more than they can keep.
Work
Three things worth your time. Each one taught me something I couldn’t have read.
2025Airline management system
Solo buildFlight booking end to end, with a state machine that refuses to let a flight board twice.
- Flight lifecycle modelled as Scheduled → Boarding → Departed → Arrived, enforced in the domain layer, not the UI.
- REST API on Spring Boot and Spring Data JPA over MySQL.
- Frontend in plain JavaScript — no framework, no build step.
2026Camera Sense
Solo buildHands-free computer control through a webcam — gesture, head and emotion tracking, all on-device.
- Tracks up to two hands and names the gesture: fist, pinch, peace, thumbs up and more; drives the real mouse and keyboard via a local Python bridge.
- Head pointer mode: move the cursor with your head, open your mouth to click, tilt to scroll.
- Emotion detection from 52 face blendshapes; room light analysis and frame stats.
- All inference runs in the browser via MediaPipe — no video leaves the machine.
2026Image Inspector
Solo buildOpen any image and see everything: metadata, GPS, colour palette, privacy flags and raw container structure.
- EXIF grouped into camera settings, capture data and GPS with decimal coordinates and a map link.
- Privacy tab ranks metadata that could identify a person, device or place — serial numbers, author, embedded thumbnails, XMP.
- MD5 / SHA-1 / SHA-256 / CRC32 fingerprints and a full walk of every PNG chunk or JPEG segment.
- Headless inspector.py engine works standalone for scripting without the UI.

On GitHub
Live, not a screenshot. Pulled from the GitHub API at build time and refreshed on a schedule.
Rendered on the server and revalidated every 30 minutes — no client-side API calls, no rate limits hit by visitors.

Internships, collaborations, a bug in one of my repos, or a distributed-systems argument you want to have with someone — all welcome.
