Hi
I am a Chartered Accountant (Indian CPA) and an MBA Finance with 18+ years of work experience. I am the owner of a small accounting firm. I provide bookkeeping and accounting support to my clients located in different countries. Together with it, I also teach students and help in solving and completing their accounting-related questions and projects.
My core area of expertise lies in teaching students

2) Finance
I teach theoretical subjects too but the above 2 are my favorites. My motto is to have an interactive class and design ways and means to make the concept interesting for my students.
Before starting off with teaching I have worked with different MNC's like GECIS, HSBC and IBM and been a part of their Finance, Accounting, and Financial Analytic teams.
So do provide your questions/queries and I'll be more than happy to answer those and hope to help you in whatever manner I can.
