Hello World!
Writing “Hello World!" as your first program is a long tradition in programming.

I've been mentoring a select group of young, motivated women who want to get into the field. Seeing their hard work, perseverance, and motivation, just like I had when I first started learning, is lovely.

I keep thinking I've finally figured myself out. Then life reminds me I haven't. Rethinking and relearning how I function in my twenties isn't easy, but it might be one of the most important things I'll ever do.

If you love TypeScript, you’ll probably enjoy C#. If you love C#, you’ll probably enjoy TypeScript. Hard pill to swallow for some, but it’s true.

All the Michael Jackson songs being back on the charts makes me want to buy a vinyl player and steal all my parents’ MJ records. It’s so good.

How much money do you spend on AI subscriptions? I'm at 20 USD a month but I feel like a lot of developers spend way more than that.

10 talks. 15 blog posts. 3 mentees. Another year on the .NET Foundation board. And, most importantly, another year of caring for and contributing to this amazing community. MVP renewal submitted. Here’s hoping for year 4 as a Microsoft MVP ✨

Vibecoded a simple React Native app with GPT Codex to track whether or not I need to check / water my plants ☘️💦 All plant apps in the play store are way too much.
Mobile app screen titled “Plant Watering” showing a “My pots” section. A weather card displays “Max 18.4°C • Precipitation 0 mm.” Below are multiple pot entries with status labels marked “Checked.” The first entry is “Pot 50x50,” planted on 04-21-2026 with 4 plants, noted as already checked today. The second is “Pot 42x50,” planted on 04-23-2026 with 6 plants, also already checked today. The third is “Pot 30x30 L,” planted on 04-24-2026 with 3 plants, already checked today. A button labeled “Add pot” appears near the top.

I decided to make the jump from Google Pixel to Samsung. The Galaxy S26 Ultra is on its way! I love DeX and One UI on my Samsung tablet, so I'm excited. I’ll probably still forever hate the Samsung app bloat though.
