I build backend systems that handle real-time communication, AI-powered workflows, and payment infrastructure — primarily with NestJS, TypeScript, and LangGraph. Currently working on TaaSNet out of Seoul.
Production work and personal systems — each built to solve a specific technical problem. Expand any card to see the breakdown.
Current Work
TaaSNet needed a backend that could simultaneously handle real-time video/audio calls, multi-step AI workflows, payment billing, and live platform analytics — each with different reliability and latency requirements.
Side Projects
Needed a reusable notification service that could deliver messages across Email, SMS, and WhatsApp through a single unified API — without coupling delivery logic to calling services.
Designing a chat system that scales horizontally requires solving cross-instance messaging, write-path reliability, and AI agent integration — all without blocking the real-time message loop.
I'm a backend engineer based in Kathmandu, specializing in NestJS, TypeScript, and real-time systems. My day-to-day at TaaSNet spans API design, AI workflow engineering with LangGraph, and live communication infrastructure.
I got into backend engineering because I like building things that continue to work reliably under pressure — queues that don't drop messages, APIs that handle concurrency correctly, systems you can debug at 2am without reading every line of code.
Outside work, I build personal projects to explore patterns I can't always try in production: distributed chat systems, OAuth2 flows from scratch, notification microservices with proper audit trails. Building things to learn them properly.
Building backend infrastructure for an AI-powered talent marketplace. Core work: LangGraph AI workflows, real-time WebSocket features, Agora/ZegoCloud integration, Stripe Connect billing, and centralized logging.
Maintained and extended the organization's website and backend systems. Collaborated with external teams on web applications and user management workflows for member schools across the PABSON network.
Contributed to a full-stack online learning platform — user auth, course management, and a Word2Vec recommendation engine. Also delivered training sessions and prepared project documentation.
Bachelor of Science in Computer Science & Information Technology. Coursework in algorithms, networking, databases, and software engineering.

I'm open to backend engineering roles, contract work, and interesting technical problems — particularly around real-time systems, AI integrations, or NestJS/Node.js architecture.
