Hi Sahil,
While it’s a prudent thought to decouple your investment from your primary income, I would say to think through this and no go by the textbook approach. While we could be cynical of the growth etc since we are in the inside but a company like Google is unique.
Also you should factor that INR keeps depreciating against USD so all things being equal, keeping a sizeable part of the investment in USD might be better. Of-course you have to factor the tax considerations etc.
A DIY approach to investments might be exciting but be-aware that Indian stock market (particularly the midcap/smallcap sector) is full of landmines - corporate governance issues, lack of innovation, lack of moats, competition from global established companies etc. I would suggest to invest in index funds if you don’t want to invest in MFs. I don’t know how old you are but remember that investment in your career has the greatest returns.
All the best.
