Data Engineer & AI Systems Developer

I ship production LLM agents, RAG pipelines, and ETL systems that turn complex data into decisions. Two years building reliable, observable AI & data infrastructure at Data n Dashboards — automating workflows with Airflow + Snowflake and engineering agents on LangChain & LangGraph.

Graduated as Silver Medalist with the highest CGPA (3.967/4.00) in NED University's Computer & Information Systems Engineering batch of 2021. Passionate about agentic systems, responsible AI, and the engineering rigor that makes them production-ready.
