Hi, my name is
Sathish Kumar.
Data Engineer by Day.
Product Builder by Night.
I build scalable data pipelines @ Propper International and ship AI SaaS products. Merging robust backend engineering with creative frontend experiences.
01. About Me
I'm a Data Engineer by trade—Python, SQL, and large-scale data systems are my bread and butter. Full-stack development was familiar territory, but shipping complete products always felt like a side quest. AI tools changed the economics.
Now I build and launch SaaS products in domains I'm passionate about. I bridge the gap between heavy backend data systems and interactive user experiences.
Currently, I build pipelines handling 1TB+ daily data at Propper International and craft AI-powered tools in my free time.

- ▹ Python (PySpark)
