You need to specialize in a specific industry, and I’m not talking about a tech field (iOS dev, AI specialist, etc). Use your skills to market yourself. Here is what businesses care about: “I can make you money” and “I can save you money”. I personally have specialized in the refrigeration industry, which is to say temperature control. So thermodynamics, heat transfer, simulations, sensors, etc. No one has ever asked me if I’ve programmed in x or used tool y, they just say they want something and I make it for them.
To do any of this you need skills but you also need to know people. That is actually the most important part.
No idea. Sedona?
