Who I am

Cillian Cooke

I’m a Computer Science student at Trinity College Dublin and co-founder of Lockup — phone-free classroom software for schools, now signing schools for the 2026/27 term. I also build Atlas, a proximity-based social platform in Flutter.

Outside of code I play football for Leinster Celtic and juggle with Trinity’s Circus Society.

Overture I

Every note is born equal

Every note is born equal, yet
An artist must decide what note comes next.
A choice that should never rest with one alone.
Equality does not mean perfection.

Across this universe, infinite lives begin.
Infinite lives end.
And I, as an artist, as a lover, must choose but one.
A choice made infinitely impossible.

With the concept of infinity,
With a gesture most romantic, I will
Divide infinity to reach you,
Until infinity becomes one.

And with that,
Multiply one to infinity.

Nothing here yet.

Atlas

A proximity-based social platform built solo.

Atlas app icon

Atlas is a social media app I’ve been building alone for over four months. No ads, no algorithmic feed, no bots. Content discovery works as a map of posts. Bluetooth Low Energy means you mostly see content from people you’ve actually been near.

Drag the interest tags — the coloured bubbles follow, the same interaction model as the Atlas map.

  • Stack: Flutter (Dart), Firebase, Bluetooth Low Energy
  • Solo: design, backend, frontend, architecture

Lockup

Software-driven focus for the modern classroom.

Lockup app icon

Lockup is the startup I co-founded with friends from college. Instead of pouches and confiscation, students check in each morning and their phone stays locked for the school day — teachers watch compliance live from a web dashboard.

We’ve incorporated Lockup Technologies Limited, shipped the student app, and signed schools for the 2026/27 term.

  • Stack: React Native
  • Student app + teacher/admin dashboard
