Hi, I'm Krisi Jain.

I'm a Data Engineer with almost four years at PwC building production pipelines in Python, SQL, and Spark, along with the validation, monitoring, and alerting around them. Now I'm at a private markets exchange, working on the analytics warehouse and the infrastructure under it, built with dbt, Airflow, and Terraform.
