Proof I use my 3D printer: a keychain display.
I pick up a keychain for my grandparents in every big city. They love to tell everybody that sets foot into their house about how their granddaughter is an international public speaker 😍😆

KCDC is a wrap and my experience of the Midwest of the US has been wonderful.
So thank you all for being so kind and welcome. And a special thank you to the people that came to my session, gave me feedback and asked questions. I really appreciate it.

C# struct, record class and record struct cheat sheet
Do you know the difference between struct, record class and record struct in C# off the top of your head? Nor do I! That’s why I put together this quick reference.

Got asked 3 times after my talk if I make video content because my explanations are so good.
Honestly? I can't handle watching my own face or hearing my voice while editing. Just being real.

Being back in a quiet office after attending Code Europe and WeAreDevelopers almost back-to-back feels really strange.

I don’t think I’m that great of a speaker, but hearing that people enjoyed what I shared and want me back really means a lot.
Whether it’s conferences I’ve spoken at inviting me again or organizers who saw me at one event asking me to speak at theirs, I’m genuinely grateful.
