Samir Neupane

I’m a full-stack developer focused on building production-ready web applications and automation that genuinely helps users and teams. I’ve developed and maintained full-stack products like a CRM, real estate, and housing services using MongoDB, React.js, and Node.js, while also bringing AI workflows into everyday operations.

Recently, I leveraged LangChain to automate professional real estate analysis and built an AI-powered WhatsApp sales agent to handle customer conversations, lead nurturing, and follow-ups using n8n, Gemini AI, Twilio, Pinecone, and CRM integrations. I also designed reliable messaging automation with a persistent Node.js + Twilio scheduler and worked on analytics dashboards with REST APIs and data visualizations (Metabase and Apache Superset), supported by performance and monitoring practices like composite indexing, Prometheus, and Grafana.
