About — Diwash Bhandari | Backend Engineer & AI Developer

Diwash Bhandari is a Backend Engineer and AI Developer based in Kathmandu, Nepal. With 5+ years of experience building scalable backend systems, AI-powered applications, and multi-tenant SaaS platforms, Diwash specializes in FastAPI, PostgreSQL, Redis, LangChain, and cloud-native infrastructure on AWS and GCP.

I build scalable backend systems, AI-powered applications, and multi-tenant SaaS platforms that ship fast and scale reliably.

My journey started with building REST APIs and real-time backend services, and evolved into designing AI/ML pipelines including RAG systems, vector databases, and LLM-powered applications. Over 5+ years, I've shipped 15+ production APIs handling millions of requests, architected secure licensing infrastructure, and mentored engineers across cross-functional teams.

I'm currently available for backend development projects, AI/ML integration consulting, system architecture reviews, and cloud telephony solutions. I work remotely with teams globally, and I'm open to full-time roles, contract work, or consulting engagements.

Beyond code, I write about backend engineering, AI/ML patterns, and system design on Medium. I also contribute to open-source projects and occasionally speak at tech meetups in Kathmandu.
