Ashish Kapoor

Full Stack Engineer | Python, Django, React, Node.js

Hi! 👋 I am Ashish, a Full Stack Engineer with 11+ years of experience.

I design and build scalable web and mobile applications across analytics, IIoT, and SaaS products. I have proven expertise in backend development with Python, Django REST Framework, Node.js, and RESTful API design, combined with strong frontend skills in React and React Native. My track record includes owning end-to-end delivery from backend services, database architecture, and API design to frontend implementation and cloud deployments on GCP and Azure.

Previously, I was a founding engineer at Rill Data Inc, a Senior Software Engineer at Quid Inc, and built the global parking platform at kerb.works. I am an open-source contributor and passionate about clean architecture, system design, and performance optimization.
