Deep Dive: Solution Architecture
Master solution architecture and turn business needs into scalable, maintainable systems
dometrain.com
Excited to announce my new course on Dometrain - Solution Architecture Deep Dive.
The #1 feedback I got on the first course was the depth. Don't worry, this ones goes deeper. Deeper into what it actually means to be an architect in 2025.

Personally, I find the usage of AI in a corporate setting regularly enables the worst behaviors to be amplified and rewarded.
A lot of people care about output vs quality or correctness. And at scale, producing incorrect things is disastrous network effects.

Love seeing all the tools being built to top of the ATProtocol 👌
I recently tried to use Github Projects and got so mad I started another side-project: skyboard.dev!
Skyboard is Trello but on the AT Protocol, a collaborative kanban board where all the data lives in your atproto repo so you control your boards forever

Been burned by “classic” AWS Lambda structure in .NET—700 lines in one file, validation, business logic, and DynamoDB calls all jammed together. Debugging or unit testing that? Nightmare fuel.
Thankfully, I've got the video just for you.

Coming up at Dot Net North, Joshua Crowe on building an extensible CLI toolkit in C#. Small, high-leverage internal tools with workflow logic, a state machine, type-safe command parsing and routing. If you're tired of messy scripts, this one's worth a look. 🛠️

One day the industry will recognize the drawbacks of AI agents and nondeterministic automation, and rediscover the UNIX philosophy of chaining together small purpose built tools in a low cost and predictable way, otherwise known as shell scripts.

I'm the first to be critical of AI, and I'm hugely cynical of it taking all software development jobs. That, alongside the huge environmental and ethical concerns.
But, I have to admit. This last week I've been using a different workflow: 🧵

I always find it nerve wracking giving a brand new talk.
When you get a some feedback after a talk that is 'I've been to a lot of conferences over the years and there are only 2 or 3 that really resonate. This talk is straight on that list"
Sample size of one, but great to hear non the less.

Very excited to be bringing a brand new talk to NDC London later today.
In it, you'll learn about some fundamental patterns of system design. Whatever 'style' of system you're building. From a monolith to a chaos inducing non-deterministic agent.
I hope to see you there!

Ever tried deploying a .NET Web API with almost the same DX as building in ASP.NET, but straight into AWS Lambda? Lambda Annotations turns your methods into HTTP endpoints w/ just a few attributes, DI still works, and w/ Aspire + the AWS emulator, local dev feels pretty native.

The overarching theme was that there’s a change happening in where human effort happens. The hard part used to be building. Now it’s knowing what you want AI to build, and which tools and systems will help you get there.

James Eastham and my latest video on software dev is up! We try to distill down when it makes sense and when not to microservice, hopefully without alienating too many folks. Have a listen and let us know what you think!
It's a great debate in modern software, do you need microservices? Or will a monolith be enough for what you need.
In the latest video in our modern software engineering series @scottgerring.com and me discuss exactly this.

From the personal computing perspective, the cloud has been a disaster — but we shouldn't run away from it.
We can solve a lot of problems by connecting our clouds, turning it into atmospheric computing.
