If you want to get promoted, doing a good job is not enough. 👉🏼 You need to be seen doing the work of the role you want. Over the last few months, I’ve written several articles about Staff Engineer, technical leadership, ownership, and breaking out of silos.

One of the main challenges on dev teams with not so much experience is the cultural mindset. Some folks think about programming and the best practices of the language used. Sorry, when you work in a tech company, you do not program, you develop software, which is beyond the programming language.

End-to-end ownership is non-negotiable Staff Engineers own projects from problem definition to delivery. You are the person people ask. You manage dependencies. You align priorities. Ownership means no hiding behind “that’s not my part”.

I did not create this memecoin nor do I endorse any memecoins. This technology is being used to automate pump and dump schemes. The "community" is recruiting "investors" and co-conspirators with upfront payments and the promise of future gains by collectively exploiting each other.

I have to admit it: when I started seeing people in my work environment using agents on their own (marketing, sales, HR…), I was surprised. Before that, I thought: “We developers will be the first to use this!" And it wasn’t like that.
