I managed to pull it off once (~2021). Got from 7.9LPA to 29LPA(26fixed) in a product company remote. At the time of applying I had 3 years full stack and 2 more years as frontend with WordPress experience.
I worked as MEAN stack developer in a service based company, learnt React.. did a bunch of projects back to back.. day and night and weekends.. even tutored for 3 months as a MERN/MEAN stack trainer (2 students)
In current market I just started new job this month but I barely had 2 offers until my last working day
The highest jump was most likely due to the market but I believe I didn't get the offer directly from ~8 to ~29
Interviewed for a lot of companies and offers against offers and had a lucky breakthrough.
It is doable for certain.
