Niranjan Sah - Full Stack Developer from Nepal
About
I enjoy building things that make computers work harder so humans don't have to.
Somewhere between React components, PostgreSQL indexes, Docker containers, AI agents, and cloud infrastructure is where I spend most of my time.
I started as a full-stack developer, but curiosity kept pulling me deeper. These days I'm just as likely to be designing APIs, optimizing databases, debugging production systems, or reminding an LLM that confidence and correctness are two different things.
I've worked across frontend, backend, infrastructure, and AI systems because real-world problems rarely care where your job description ends.
I like building products that survive real users not just demo day. After all, users have an incredible ability to test edge cases you never knew existed.
Outside of writing code, I'm usually learning something I probably didn't need to know... until the next project proves otherwise.
Based in Nepal 🇳🇵, open to relocation, and always excited by teams solving difficult engineering problems.
