Hi, I can connect aws instance on winscp. I did it before for many customers. FYI, I am aws certified solution architect associate and sysops admin associate. I have 5+ yrs experience handling server administration and deployments on AWS, Linode, Digital Ocean and 13+ yrs IT industry experience. Till date, I had deployed 200+ sites on AWS.
Let's shake hands and get started. I can assure quick and quality delivery.
