PythonI train working professionals and students in data science — Python, SQL, Power BI and machine learning — at Ambuja Foundation in Jaipur. I also work as an MIS/data analyst, and I hold an MSc in Data Science alongside a background in Electronics & Communications Engineering.
This site is a shared learning journal. I write here as I study new topics, and my students write here too as they learn — every article kept in simple, clear English so it's easy to follow regardless of background.
Once a topic has been tested here in writing, it becomes the outline for a short video lesson. The first course is being scoped now — get an email the day it opens.
