About

Kathmandu valley at night, lit up for the Tihar festival
Kathmandu, Nepal · where I buildPhoto: Bikalpa Pokhrel / Unsplash

I've spent the last two years putting AI in front of real people: patients calling a clinic, clients calling a law firm, customers proving who they are on camera.

I started on backend APIs and CI/CD, brought that discipline into Video KYC and RAG at Code Himalaya, then built a voice agent answering a US hospital's phones at MeetGabbi. There, a wrong answer isn't a bug report. It's a patient left waiting.

I'm finishing my BSc IT (Hons) in Kathmandu, where my final-year project teaches the city's own traffic signals to adapt. I speak Nepali, English and Hindi.

FAQ

Before you reach out

Questions recruiters and clients ask me.

What roles are you looking for?

AI/ML engineering roles focused on voice AI, AI agents and RAG, where the work ships to real users. I'm also open to contract and fixed-scope projects.

Have you shipped to production, or only built prototypes?

Production. My voice agents ran for a US orthopedic hospital, ARC Psychiatry and US law firms. At Code Himalaya I deployed AI services with Docker, AWS and CI/CD.

Can you work remotely with a US-based team?

Yes. At MeetGabbi I worked remotely from Kathmandu with a team in Cincinnati, collaborating with product and engineering on healthcare and legal features.

Can you handle sensitive or regulated data?

I've built HIPAA-compliant voice systems with compliance-aware conversation design. My Video KYC system kept face embeddings, audit logs and ID documents securely in Amazon S3.

How do you know an AI system is actually working?

I measure it against honest baselines. In my traffic project, every trained model had to beat a random-control baseline, not just fixed timers. When it didn't, I said so and worked out why.

How quickly can you start? Do you have references?

Email me your timeline and I'll reply with my availability. References from past managers and colleagues are available on request.
