Niranjan Sah - Full Stack Developer from Nepal

Full Stack Developer @ Kumari AI

Overview

About

Most full stack devs can ship a feature. I build the system around it.

Architecture, APIs, cloud infrastructure, AI integration, deployment pipelines. I take ownership of the full picture, not just my slice of it.

Over the past few years I've worked across the complete stack - React.js, Next.js, TypeScript, Node.js, FastAPI, Django, PostgreSQL, Redis, Docker, AWS, Firebase, Flutter - building production-ready platforms that don't just work on demo day, but hold up when real users arrive.

What I actually care about:

→ Clean architecture that the next developer can understand

→ Performance that users feel, not just metrics that look good

→ AI-powered products built to solve real problems, not win hackathons

I've contributed from idea to production system design, API architecture, database modeling, containerized deployments, CI/CD, and cloud hosting. I don't wait to be told what to build next.

I'm based in Nepal, open to relocation, and actively looking to work with international teams and global products where I can contribute from day one.

Open to junior - mid full stack & AI engineering roles startups, remote-first teams, and technically ambitious products.
