I also have a "portfolio" site, and I am in a career path where none of my peers have a portfolio site. There I show off my technical expertise in a handful of software packages that are crucial to my career. The domain name is a technical name about these software packages.
Last year I concluded a successful job search and landed a very good job at a very good company. I used my personal website domain name as my contact, and highlighted my portfolio site in my resume to back-up my experience and expertise.
It was often a topic during my interviews.
These days I am studying Data Analytics / Data Science (and now ChatGPT/ML too) in order to augment my skillset and possibly make a career pivot. I have taken a very short very good domain name about data and I have started to blog about my perspective of Data Analytics/Data Science from my present career track (they kind of intersect / overlap a bit), documenting my learning progresses, collecting resources etc... this actually has landed me 1 interview at a great company without applying (the recruiter saw my LinedIn profile and this site); but the job was way above my head, but it was a good experience.
I advice everyone who asks me for job hunting advice the same: don't job hunt, build a career, and also build an online presence and a portfolio. I am no good at helping people getting a job in 30 days or less, but I am very good at coaching people in getting a great job 5-10 years down the line, if they start now.
Moreover, writing every day (I do that on my own Google Docs), helps think better; better thinking leads to better problem solving; which leads to better writing.
And then ChatGPT came along, and it's changing everything by augmenting people's capabilities.
Stay tuned.
