ENGINEERING WITH INTENT

More than shipping code. I build for clarity, reliability, and real outcomes.

I’m Ashwani, a Full Stack and Backend Engineer working at the intersection of product engineering and cloud data systems. At Cognizant, I architect and maintain distributed Azure pipelines that ingest data from multiple vendors into reliable lakehouse layers.

Before that, I shipped 20+ production features across six applications at Banao Technologies, designing REST APIs and backend services used by more than 10,000 monthly active users. I care about resilient architecture, thoughtful interfaces, measurable performance, and leaving systems easier to operate than I found them.
