Looking to start a career

I'm a Singaporean, who just finsihed serving National service and is now looking forward to start his career in order to have a more secured future and work in a company that I am interested in.

Looking to work in career that does not limited to myself to my education and what I've studied, which is Diploma in Engineering with Business. Would love to explore the different jobs scopes but at the same time focused in building my career so that I can start a family too as I am a family guy.
