The Twitter BIO can't be underestimated.
I am by far no Twitter expert but I think a good BIO should clearly explain your main interest and what can I expect to see in my newsfeed from you, if I decide to follow you.
Share your BIO and and let's ALL exchange feedback between each other.
Here is mine:

WDYT?

Here is mine featuring a custom made channel art and minimalist bio.
Nice. Very on point.
Thanks

Looks clean! :svk:flag:
The text in your bio is very clear, I know what you do and it doesn’t feel like your selling to much. But your hero image is slightly unprofessional looking relative to your photo. I suggest a more abstract code sample that looks more visually pleasing. I’d be happy to help create one if you’d like.
I would love some feedback on mine! https://twitter.com/joemasilotti
Thanks. How would u improve the hero image? Is a test execution from one of the test files in my blockchain eBook. Maybe that's not very clear?
I like your as well. The emphasis on clean, testable code paints me a clear picture about you.
You could try generating it with Carbon. That way you have more control over the width and such.
It was carbon generated :) Anyway I took your suggestion and created a specific new banner :) Check it out! More feedback welcomed :) Let me know if u want also any extra feedback
Love to know what you think! I'm twitter.com/danielstedman (I don't know how to add a photo here)
I like this a lot: Opinions not mine; they are yours.
To add a photo, upload it somewhere online like https://imgbb.com/ and then add here the syntax in this form (without quotes and spaces): "! [description] (url) "
Here's mine:

Nice. I interpreted it as: "You like to build teams and products because/and you are a teamlead"
