As a freelance Backend & AI Systems Developer, I architected a Node.js and Express.js CMS with role-based access control, REST APIs, and PostgreSQL. I also built workflow automation pipelines connecting APIs, databases, and AI services.

At CSEC-ASTU, I developed a backend for a Student Management and Lab Portal and worked on early RAG prototypes and chatbot workflows. I’m also building a cross-platform mobile app with a companion Express.js backend, and have developed RAG and AI agent projects using LangChain and open-source LLMs.
