Things to Downplay
Firstly, a major concern for a lot of employers would be the "serially starting up"? Because one thing that worries employers is a lot of job changes in a short period of time. (For the obvious reason that they're worried about you jumping ship to a new job at an inconvenient point)
The other would be "burned out". Nothing says "hire someone else" like "I've done my best work, now I'd like to settle for you". You need to find a more positive way to describe what you're looking for in a company.
What to Emphasise
At the end of the day, CV's fall into two types. One is the one you put online for recruitment firms. In this case, just dump literally EVERYTHING on it. Every programming language you'd be willing to work in, every soft skill you possess, every place you've worked for. They're basically using a big ol' regex, and you want to catch as many jobs as possible so you get a good range of available jobs.
The other CV is the one you write for the companies you're actually seeking out yourself. These are the ones you tailor, for example emphasising that you've got very strong programming skills in the area the company you want to work for works with, and why you want to work for them.
Note that occasionally, a recruiting firm will contact you based on the former CV, and it's often worth drafting a CV of the latter type, in order to get past the far more stringent hiring department of the companies they send your CV on to.
The other thing that helps with either kind of CV is examples of how you've applied your soft skills.
For example: "Very Customer Focused" vs. "Customer Focus: During one project dealt with the client on a weekly basis, clarifying requirements and demonstrating prototypes over the entire project lifespan. This helped to build trust and contributed to being offered further work from this client."
The first will be picked up by the regex, along with every other CV on the internet. The second will prove that you actually did something they can talk to you about in interview, and will be picked up by the regex.
Basically, write something that hits the requirements so that it's listed when they look for it (programming languages, soft skills), but when you read it back makes you think, "I'd like to talk to this guy and find out if he's actually worth hiring". And for god's sake don't add anything that gives them an excuse to reject you. Any firm worth working for is getting multiple applications for each place. If they see something that makes them go hmmmm, that allows them to trim the stack of the CV's down by one.
