Lone Logic
🍎 Lone Logic | Code in silence. Build with clarity.
💡 Exploring code, systems, and retro tech—one solitary project at a time.
I’m a practicing orthopedic surgeon, but I spend most of my free time building systems and fixing old tech.
From GUI applications to retro PCs, from soldering circuits to reviving dead hardware—
I make things quietly, sometimes beautifully.
If you’re someone who enjoys creating, not just consuming—welcome.
