Hello,
I have been developing since 1995, and since then, have come across a lot of issues/up-gradations/enhancements and successfully implemented them.
Managing the urgency for the clients, in any timezone is the best aspect i have managed.
My main development technology since then is VB, ASP, C#, SQL Server/Oracle.
Changing the code in a way to adhere to the current coding standards of the app/website is must, to better handle the handover/transfer/understand task to other developers.
Hope to hear from you soon.
Thanks,
Mansoor Ali A
