1] Build a capabilities slide deck.<p>Frame this exercise as what you would prepare if you were given the opportunity to do a 15 minute formal pitch of your capabilities to a room full of potential clients&#x2F;employers.<p>Advertising Agencies and Consulting companies often have this as a section of their pitch decks. This is the &quot;generic&quot; part in which they are telling potential clients why they are generally capable and able to handle whatever will come up in the course of the project and they focus on the people and skills that they think make their agency stand-out while also assuring clients that they have all the &quot;table stakes&quot; covered.<p>The deck will help you with interviews and networking. How do I tell my story succinctly and engagingly?<p>2] Create an online portfolio website and other mini-sites. 
Build a portfolio site describing your accomplishments in various projects at your current newspaper job and include URL to relevant page. That portfolio site should also link to 2 or 3 mini-sites that demonstrate various sub-sets of your skills in action.<p>This is helpful because you can just send someone you are networking with a single URL that lets them explore who you are and what you can do.<p>3] Map out your skills. For each skill: label, short description, depth of experience, breadth of experience, assessment of your skill level, clear path toward improvement, enjoyment level and local market demand.<p>What this map will help you to do is decide where to focus your specialization budget, your time, money and intellectual energy. Ideally you would find a skill where you already have a nice breadth and depth of experience, market demand is at least moderately high and that skill has a clear path forward for improvement such as online courses, great books for moving toward expert status.  Of the things you have listed, Javascript stands out as the skill that has market demand and a clear path toward expertise on top of your practical experience. It also has the virtue of being demonstrable.
