Hi, I'm Amit Karn
4+ years building web platforms, mobile APIs, and GPS/IoT tracking systems. Specializing in Laravel, Next.js, and PostgreSQL. Currently pursuing MS in Data Science.
More than just code
I'm a Senior Full Stack Developer with 4+ years of experience building web platforms, mobile APIs, and complex GPS/IoT systems from Kathmandu, Nepal.
I specialize in Laravel, Next.js, and PostgreSQL, with a focus on writing clean, maintainable code and building infrastructure that actually scales.
I'm currently the Senior Full Stack Developer at Zum Ride— Nepal's first e-cycle rental startup — and simultaneously pursuing a Master's in Data Science at Softwarica College (Coventry University), working on applied ML research.
Outside of work, I love exploring how machine learning can solve real-world problems in urban mobility and environmental health — specifically in the context of Kathmandu Valley.
