Outside the Loop or out of the context of the post, such as in the header or the footer and even sidebar area in WordPress templates, the_ID() cannot be used as a function. Instead, $post->ID is used to return the post ID. $post is a global object that holds various information about the posts displayed on the page.
I've worked in tech for over 15 years, mostly on digital analytics and automation for large enterprises. My work usually lives at the intersection of business problems and technical implementation — cloud architecture, data engineering, analytics consulting, and the project management that holds it all together. Over the years I've shipped a fair number of complex projects, the kind that take a quarter of patient work before anyone sees the result.
I lead a team of analytics developers, and most of what I've learned about leadership is that it's mostly listening, removing obstacles, and being honest when something isn't working. I like mentoring, I like watching people grow into harder problems, and I'm usually the one trying to turn a tangle of technical detail into something a non-technical stakeholder can actually act on.
