By age 30, many peers have decided to focus on Cisco, on Oracle, on Microsoft dotnet, on IBM, on SAP, on Powerbuilder. Other choose to focus on a domain like online gaming, financials …
(By “focus”, i mean 50%-100% of their tech experience is related to the chosen field.)
I always feel what if one day you discover you don’t like your role in that particular ecosystem, or the vendor starts making questionable moves, or you don’t like the vendor’s tech support, or u notice their discrimination policy .. you would feel locked in, cos you have invested too much into it, putting all your eggs in a single basket.
In my case, i have several years experience in each of
– solaris, linux, hpux, freebsd
– Oracle, mysql
– java, C, perl, php
– weblogic, tomcat, sunone
