I'm a senior frontend/fullstack engineer and also a team lead of 7 people. I know stuff about browsers, devtools, js, html, css, building layouts, frontend frameworks, backend servers, writing good APIs, optimizing stuff, writing readable code, deploying the app to a server, automating deployment pipelines, etc. You name it.

I want to start writing articles and my question to you is:

• What is the topic you wish there was an article about?
• What topics most of the articles only scratch the surface?
• What do you think is cool, but you don't know how to do?
