[Verse 1]
Lines of code at midnight glow
Coffee cold but spirits high
Every bug a chance to grow
Every fix a battle cry

[Chorus]
We build the future line by line
Open source, the code is mine and yours
Together we design
A world that runs on what we pour

[Verse 2]
Pull requests at dawn arrive
Reviews sharp but always kind
In this repo we're alive
Leaving legacy behind
