Hi,
I am a 6+ yrs experienced software professional who has worked on multiple projects in CMM Level 5 companies. I have mentored many of the new joinees for my projects and worked as Technical lead as well. I have been into multiple JAVA related technologies and was a fully qualified FullStack developer. So, I think I would be able to solve your doubts easily. Depending on the complexity of work I can charge you. Since you are from India, we can discuss the rate and doubts depending on the time that is required to be spent.
Hope we will have a great work together :)
Thanks and Regards,
Anusha Koraboyina
