What Is madelinemiller.dev and Who Is Maddy Miller?

madelinemiller.dev is the personal portfolio and technical blog of Maddy Miller, a software engineer who goes by the handle me4502. The site describes her as a Senior Software Engineer on the Clipchamp team at Microsoft, originally from Queensland, Australia. It hosts a portfolio of her software work, a collection of technical articles, and a showcase of experiments she has built over the years. If you want to know who is behind the Minecraft mods WorldEdit, WorldGuard, and CraftBook, or you're looking for her writing on developer experience and web technology, this is the place to start.

Who is Maddy Miller?

According to the site's own introduction, Maddy Miller is a software engineer and computer scientist from Queensland, Australia. Her professional role is Senior Software Engineer at Microsoft, working on the Clipchamp team. Outside of work, she develops the Minecraft mods WorldEdit, WorldGuard, and CraftBook, and contributes to a range of open source software projects. The site also notes an interest in deep-diving into technologies and optimizing performance.

For readers who want a fuller picture of her involvement in the Minecraft community, the site points to a separate in-depth page on her contributions, as well as a large Q&A she wrote for the ten-year anniversary of her article writing.

What can you find on the site?

The homepage frames the site as three things: a portfolio, a blog, and an experiments showcase. In practice, visitors will find:

• A software portfolio — a record of projects she has built.
• Technical articles — regularly published blog posts, mostly in the Technology category, with some in General.
• Experiments — a showcase of things she has tried over the years.
• Contact and background pages — including a contact page and a more detailed "about me" section.

Recently updated posts

The homepage lists recent articles with dates, categories, tags, and reading times. Three examples give a sense of the content mix:

The July post is a retrospective on building custom plugins a few weeks after getting a TRMNL X e-ink screen, described as a process that differed from expectations. The June post is the ten-year writing anniversary Q&A mentioned above. The April post is an explainer on CGNAT, arguing that most discussions miss the situations where it is unavoidable and that many users still treat IPv4 scarcity as theoretical.

Who is this site for?

The site is most useful if you fall into one of these groups:

• Minecraft server administrators and mod users who want to know the developer behind WorldEdit, WorldGuard, and CraftBook, or find her community contributions.
• Developers interested in technical writing on developer experience, web infrastructure topics like CGNAT, and hardware experiments such as e-ink plugin development.
• People evaluating her work — recruiters, collaborators, or open source contributors — who want a portfolio view rather than a resume.

If you're looking for documentation for the Minecraft mods themselves, this site is a pointer to her work rather than the mod documentation; the homepage directs readers to a separate page for her Minecraft contributions.

How to use the site

1. Start at the homepage to get the short introduction and the list of recently updated posts.
2. Use the software portfolio link to browse projects.
3. Use the articles link to read blog posts beyond the recent few.
4. Use the more about me link for background, and the contact page if you want to reach her.

One practical note: the recent posts carry dates in 2026, so treat the homepage as a snapshot of what was newest at the time you visit rather than a fixed archive. For anything beyond the recent list, follow the "See More Posts" link.
