I'm Nirajan Karki — I build software by day, debug the human condition by night, and have arrived at one philosophical truth: all systems tend toward chaos, and my job is to delay the inevitable with clean architecture and questionable caffeine intake.
I build bulletproof backends, craft pixel-perfect UIs, and occasionally make APIs that don't break on random Tuesdays.
When I'm not explaining to rubber ducks why my code isn't working, I'm turning coffee into full-stack solutions with Python, JavaScript, and whatever shiny new framework everyone's talking about this week.
