Namaskara.

Shri S.L. Abhyankar is a retired engineer, based in mumbai. He is pretty fluent in Gujarati, Marathi, Kannada and of course, Samskrit.

He has a couple of blogs, including gItA, vyAkarana, where he opines that Samskrit could be learned in a different way.

He is a very humble man who, despite the tremendous amount of work he's doing, comes across as a perpetual learner.
