WordPress agencies: If you're an agency who uses WordPress, I've been working the last few years on creating a set of tools for managing WordPress sites. I've got a CLI, WordPress plugins, and a WordPress control panel that all work together, and it's what I currently use in my daily job right now.

Crypto enthusiasts: I recently spent a day creating a website that tracks the price of the cryptocurrency Hedera Hashgraph. It was actually an exercise in seeing how fast I could make a website load, and I'm pretty sure you're not going to find a faster price tracker than this.
Photographers: I've written some articles you might find useful on composing images, manipulating color, and noise reduction at mrme.me.
