I have done a two month intership at HUBILO where I learnt to manage data in EXCEL sheets. Actually I was supposed to collect data about various colleges(Around 600) of India and I had to fill them in EXCEL sheets. So, I had a very good experience working on spreadsheets. Moreover, being an engineer, I had worked on EXCEL a lot during my college fests.
I know, I am a new freelancer but I promise, I won't let you down if given a chance. Let's make a deal. I will work on your sheets for one day then if you don't like my work then you won't let me work on it. And you don't have to pay anything for the first day! But, if you like the work, then 10% on day 1 as down payment. And the rest after the completion of work.
I hope you like my proposal. Looking forward to chat.
