One of my mentees, Raissa, has started writing blog posts about what she’s learning with C#, with the goal of becoming a C# developer. If you’re just starting out with C# (or simply curious), you should definitely check out her 'Hello World' post 👇 rlimondev.substack.com/p/hello-world

The new "5 Years" ring on my MVP award looks so good 😍 #mvpbuzz

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 got an email saying someone was trying to bid on a domain I own. Nice try. It's mine.

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.

My partner: builds a career that only works at a handful of Dutch companies, on location. Also my partner, atleast 10 times a year: "Should we buy a house in Sweden? Maybe some land? Maybe just rent there?" This man has some wild plans 😆

Sometimes I do miss being stuck on a silly little bug and scrolling through Stack Overflow for hours, then finally feeling the rush of solving it

Talk 2/2 of Update Conference has been given. Now I'm tired 😴 Don't worry, there were people sitting there while I was speaking.

My calendar for the next quarter is looking pretty empty. Looking for an experienced speaker for a conference in Europe or online, or a meetup in the Netherlands or online? Hit me up 🔥

I’m so out of sync with Dutch working life that I kind of forgot today is a holiday. Whoops.

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.

Went outside and touched grass instead of my keyboard.

I'm so sorry for your loss 🫂

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.

Not an engineer? You might be exactly who the .NET Foundation Board is looking for. This election cycle is focused on leaders in business, partnerships, operations, marketing, and community. dotnetfoundation.org/board-electi...

I don't have a sticker collection habit at all. Nope. Not me.

My grandparents love what I do and I always take keychains with me for them when I get back from a foreign country. And the keychain board is finally full! Here we have Brussels, Texel, Seattle, Prague, Kansas City, Stockholm, Lichtenstein, Berlin, Zürich, Warsaw, Tokyo and Luxembourg 🤩

I have been coding in C# for years now but I still need glasses 🥲

I found this ancient business card. This was back when I was still working as an IT support employee. This design still kind of slaps tbh

It's this kind of day...

Finally got a well needed upgrade on the 3D printer. I tried to print a multicolored MVP coaster with my new AMS system. It's not a perfect print but I'll be queen of the 3D prints one day! 🤩

GitHub's reliability isn't great right now. I propose a return to the good old days. Back to FTP.

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.

My magnet collection is very Microsoft oriented

My mom and my grandpa both have a LinkedIn account just to be able to view my posts. I think it's the sweetest thing.

I graduated 2.5 years ago thinking I had it all figured out. I was wrong. The biggest lessons haven't been about the work itself, but about what I need mentally, emotionally, and physically to actually sustain it. It's been an interesting journey for sur

Partner: "Should I buy a new laptop? My 8gb on RAM on my MacBook is not enough" Me: "Why don't you just upgrade your older Lenovo laptop?" ThinkPads rock! You can't convince me otherwise.

Concert on Monday Meetup on Tuesday 2 workshops on Wednesday We're making the most out of this week!

I'm considering writing Dutch content on C# and VueJS 🤔

I’ve realized C# is just too concise. I’m craving more words. Today, I begin my journey into Visual Basic. Finally, a language that understands my need for 'End' 'If' and 'Then' statements.

Last day of MVP Summit. Let's do this! #mvpbuzz #mvpsummit

What a blast for the past at the Archives on Microsoft campus #msarchives

MVP Summit tip 172: Always, ALWAYS, take earbuds with you to networking events This tip also works for other conferences / summits / get-togethers

Just picked up my badge! #mvpsummit

Checking out Microsoft Campus while it's still calm with @johansmarius.bsky.social . Only 1 day left until MVP Summit kicks off.

First thing to buy in the US is always purified water. I hate the chlorine tap water out here.

Slow weekend after VueJS Amsterdam has completely drained me mentally ✨

🙌 Great practical talk from Louëlla Creemers @louella.dev at Vuejs Amsterdam. “One Year of Vue: Mistakes I Made So You Don’t Have To.” 👩‍💻 A look at real challenges from rewriting a production app from Vue 2 to Vue 3 and how architectural decisions evolve as projects grow. #vuejsamsterdam #vuejs

There is no stage like the @vuejsamsterdam.bsky.social stage

Sometimes I have to deal with Python Flask and then I'm extra thankful for ASP .NET

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.
