Worst freelancer, Never work with him, He will make you believe that he will put extra efforts and will do anything to bring business or contracts, Since 1s day when the contract was awarded he disappeared, He me cleverly requested me to fund the first milestone in advance so that he can use that money to buy the subscription etc. but nothing happened and I ended up losing money
