I'm happy to announce that key upgrades have been successfully completed.
I've moved this website, along with most of my other services, into Docker containers. The motive for this is because it streamlines and compartmentalizes your environment—no more "it doesn't work on my machine". The latter feature also decreases your host's attack surface by logically isolating the contained subsystem.
The second important change concerns the frontend. Though I focused on backend early in my career, the experience of working as a full stack developer helped me challenge my frontend insecurities.
Now, I may not be a UI/UX designer, but I've picked up on some of their cues. Left to my own devices, I prefer making, or at least starting with, minimalistic designs. So that's what I've gone with for the website. I'm using Bootstrap, which simplifies the process of making the site design more responsive across different viewpoints (another skill I picked up from my professional work).
In the spirit of Agile, I'll keep iterating and improving the website.
