I have wanted to move my blog into my personal site for a while. Actually, I wanted to do this last year, but like a lot of side projects, it kept sitting on the list. I would think about it, open the repo, look at the amount of work, and then convince myself that Hashnode was fine for now. And honestly, Hashnode was fine. The issue was not that Hashnode was bad.
I started using Codex the obvious way: point it at a repo, ask it to make a change, run the tests, and help me clean up the diff. That is still useful. But lately, I’ve been using Codex for a lot more than just code. I use it to help with blog posts, talks, docs, Azure demos, browser testing, research, and random follow-ups that would otherwise sit in my head for too long.

A few years ago(2018), I was working full-time in Tech Support. The job paid the bills, but it wasn’t what I wanted to do long term. I tried staying back after work to study AWS, but most days I was drained. After troubleshooting tickets for 8 hours, my brain was fried. So I made a small shift — I started coming in early. One hour before my shift started, I’d grab a coffee and study.
