Hi , Just went through your requirement . I'm an OSCP and CISSP certified security researcher, found critical vulnerabilities in Google, Microsoft , Adobe, Twitter, MasterCard, WesternUnion , Royal bank of Scotland and many more.
I have good experience with Aws Instance and previous tested it and reviewed the configuration as well. I'm comfortable to show you certificates and my name in 'hall of fame list' of these giants ....Have rewarded by all these organizations many times and privately invited by them for Securing their IT infrastructure/server and domain.
I have been appointed by US based bank AGfirst (Farm credit bank) to perform Infrastructure /Server/Web application Penetration testing and worked for many financial giants across the world.
I'm desperate to help you secure your Web application/server and IT infrastructure .. Waiting for your revert. Thanks Geet
