Hi, I am Delphi expert with more than 15 years of experience in various areas including complex client/server applications with Indy used as communication library. I've also worked in REST applications, server in Delphi and with clients in Delphi, JS.
I also have large experience in performance optimization and debugging, as well as in FTP/SFTP (I've built generic purpose client). As an example of my work you can check System Navigator from www.exeone.com.
