Unfortunately Mr. Ashok Swain is correct. I think there are three types of software that those huge Indian IT companies work in :
1. E-retail apps like for the food delivery company Zomato or taxi booking company like Ola. But this expertise has come in handy to write software for maintaining and coordinating COVID information and records.
2. The banking software Finacle from the company Infosys and the financial accounting software Tally from the company Tally Solutions.
3. Writing subcontracted software for Western companies like HCL did for Boeing (

And within India there are crucial customers for locally written software such as for the space and military sector.
But yes, despite 160,000 computer engineers graduating from Indian colleges every year and this being true for at least the last twenty years which means that there are at least three million computer engineers in India, there is not a single operating system software within an Indian name. Unfortunate.
In 2010 the Indian military organization DRDO's chief
declared that the org will devise a "futuristic" operating system software soon :
Now, eleven years on in 2021, DRDO still hasn't devised that operating system.
But neither has China.
