Welcome to my professional space! I'm Pankaj, a Data & AI Engineer with over 7 years of remote experience, specializing in LLM/RAG systems, data pipeline architecture, and AI workflow automation using tools like LangChain and n8n.
Currently, I’m advancing my expertise through the accredited B.Sc. in Data Science and Artificial Intelligence program at IIT Guwahati, one of India’s premier technology institutes. The program emphasizes practical, industry-aligned learning across data engineering, MLOps, and applied AI, strengthening my ability to build scalable, innovation-driven AI solutions.
I design and develop intelligent, production-ready systems that merge data engineering principles with modern AI integration. From constructing reliable ETL pipelines to embedding Large Language Models (LLMs) into business workflows, I deliver end-to-end AI solutions that enhance automation, efficiency, and decision-making.
My work focuses on Retrieval-Augmented Generation (RAG), LLM orchestration, API integration, and AI-driven automation across cloud environments like AWS and GCP.
Passionate about global innovation in AI, I’m eager to collaborate with forward-thinking, data-centric teams to build the next generation of scalable, intelligent systems.
