About
Placeholder bio. A few paragraphs about who you are and what you do. This first one might cover the shape of your career — what you build, the kinds of problems you gravitate toward, and roughly how long you have been at it.
A second paragraph is a good place for specifics: the domains you have worked in, the tools you reach for, and anything that would help a reader decide whether you are the right person to talk to about their problem.
A third can be more personal — what you do away from a keyboard, what you are currently learning, or what you are looking for next. Anything longer than this probably belongs in its own post.
