Summary
Engineer and founder based in Nepal. CTO of G Robotics, founder of Garud Cyber Defence and Bhairav SMS, and co-founder of CMD Nepal. I build across the whole stack — full-stack web, Linux infrastructure, cybersecurity, telecom and SMS (SMPP / A2P) systems, RF hardware, embedded ESP32 and drones — and turn it into working products.
Roles
I lead the tech for counter-drone systems, AI, robotics and VTOL hybrid platforms — plus hands-on training programs.
Defensive security services and infrastructure hardening for organisations in Nepal.
Enterprise A2P SMS routing, OTP delivery and CPaaS platform — SMPP, delivery reports, credits and billing in one place.
Regional cybersecurity research and development.
July – August 2025.
From June 2025.
Security analysis, telecom/CPaaS infrastructure and web platforms.
Selected projects
SMPP bridge and admin panel that ties every message to its route, delivery receipt, cost and the client's remaining credit. Multi-currency reseller settlement built in.
ESP32 Cheap Yellow Display build that sniffs Remote ID broadcasts and plots nearby drones on a live radar screen.
Portable field kit in a custom 3D-printed enclosure for RF work and on-the-go Linux.
Offline voice assistant that runs locally — no cloud, no data leaving the device.
Quadcopter sim with deterministic physics and flight-controller-style rate control, rendered in the browser.
Proxmox VE on a Dell PowerEdge T130 plus VPS nodes, stitched together with MikroTik routing and WireGuard tunnels.
Monitoring for ~100 devices — OLTs, ONUs, MikroTik routers and switch ports — with Telegram alerts.
