Manjot Singh

I am a Computer Science and Engineering student and automation-focused full-stack developer. I build practical systems using Python, JavaScript, Next.js, Node.js, MongoDB, LangChain, and LangGraph. My experience includes developing an LLM-powered invoice automation workflow that extracts invoice details, categorizes records, and exports structured data to CSV and Excel-based workflows. I have also built AI career guidance, browser automation, and URL-shortening applications with secure authentication, analytics, rate limiting, database indexing, and scalable backend APIs. I enjoy turning manual processes into reliable automated workflows and building user-focused web applications.
