I think the simplest is doing small consulting projects. There are often people looking to launch an app or build a prototype or whatever it is where you can work a couple hours a week on it and make a pretty good rate.
In my experience if you are a pretty good developer and good at communicating, you can find small bits of work without much effort. Now I'm doing a lot of consulting so charge more, but previously I would pick low stress / low mental fatigue projects, with people I enjoy working with (often pre funding prototypes), and charge between $65-$85/hr which could be another $500-600 / month at 2 hours per week.
I also never used any of the freelancing sites, and always found work through personal connections, since it dramatically lowered the risk of getting a bad fit for me.
It's not always prototypes necessarily but mostly it's about reaching out to people you already know and letting them know you are helping people on the side with software work.
I was very lucky in that I happened to be good friends with a super-connector type person who always has people asking him for help. If you know other people who are doing consulting work, you can talk to them, if they are good they won't be particularly protective because good people always have more work than they can do.
In general, it can take time to build this up but in my experience it's valuable to see how you can help / give to others around you, and it will come back to you at some point. You have to learn to avoid the time wasting clients and people who look for you to do spec work, but after you've learned to spot them it's not so hard.
spec = specifications. This could be 1. requirements gathering (use case focussed in words of client) -> 2. functional specifications (use case focussed in terms of developer / exhaustive) -> 3. technical specifications (low level plan on how to implement). Often 3. and sometimes 2. aren't done explicitly, but are part of iterative / agile methodologies. 1. however, must still be done imho
Thanks. I did know that spec by itself is short for specifications - I'm a developer, and also have software engineering experience, so knew abut your points 1 to 3. My point was that spec work seemed like something else. Also see my other reply to a child comment to yours.
I think in this case, the parent meant working speculatively [0] which can be seen as risky for some, but also a way to get some reputation & awareness.
Thanks. Yes, I think this is what the original comment meant that I was asking about. Now I remember where I read the term "spec work" - it was some weeks ago on avc.com, Fred Wilson's blog. And someone gave the same answer there as you, IIRC.
