+title: My First Post
+date: 2026-03-06
+summary: Welcome to my blog! Here I'll share thoughts on software development, projects I'm working on, and things I find interesting.
+tags: [dev, personal]
+---
+
+# Welcome to My Blog
+
+I've been meaning to start writing about the things I build and learn, and I'm finally getting around to it.
+
+## What to Expect
+
+I plan to write about:
+
+- **Projects** I'm working on, like this website and the other things on my portfolio
+- **Software development** tips and patterns I find useful
+- **Problem solving** approaches that have helped me grow as a developer
+
+## Why a Blog?
+
+Building things is great, but explaining *how* and *why* you built them is just as valuable. Writing forces you to organize your thoughts, and hopefully someone else finds it useful along the way.
+
+Stay tuned for more posts!
