01About

I work end-to-end across the data lifecycle — designing ETL/ELT pipelines, building and deploying machine-learning and LLM applications, and turning messy data into reliable, production-ready products. I care about clean code, honest evaluation, and solutions that actually ship. Currently going deeper on agentic AI, Snowflake, dbt, and Airflow.
