About
Premesh Devasani
I'm a data engineer and AI systems builder focused on the intersection of reliable data pipelines, modern LLMs, and real-world analytics. I build things end-to-end — from raw data generation to production-ready dashboards and AI agents.
What I'm focused on
- →Building analytics infrastructure that scales — BigQuery, dbt, and Python pipelines that don't need constant babysitting
- →AI-augmented analytics — using LangGraph and Claude to turn natural language questions into precise SQL answers with charts
- →Shipping production-quality work — not notebooks or prototypes, but deployed systems with auth, error handling, and real data

- dbt Core / Cloud
- Python (Pandas, Faker, SQLAlchemy)
- Apache Spark (PySpark)
AI & Apps
