I have been doing this for a couple years now. I am about to make some big changes, as a result of the side work taking off.<p>I work early&#x2F;late, so that side work wouldn&#x27;t conflict with my day job. I worked Saturdays.<p>I&#x27;m a systems guy, not a dev as much as I <i>really</i> want to be. I&#x27;m getting into automation stuff, and learning enough programming to help me be a better sysadmin (Ruby, for Chef).<p>I&#x27;m always reading, and working to improve my skills (technical, and otherwise)<p>I took every opportunity to do side work, for some extra money. It&#x27;s paid off well, and now the scales are tipping to where I&#x27;ve easily replaced my day job income.<p>I have an email address listed in my profile. I&#x27;d be happy to talk more, if you&#x27;re interested.
