I'm Aswin, a Data Engineer from Chennai, India. I build production data pipelines by day and ship SaaS products that solve real data problems by night.
I care about end-to-end ownership — designing the schema, writing the ETL, deploying the API, building the UI, and making sure users can actually get value from data.
