About Me
Background I started my career as an intern C# developer, and ever since I have been hooked on all that is software. I have developed software such as security applications, eCommerce systems, data integration platforms, and much more.

Ideas of an Imposter
The Imposter Syndrome is like the fog of war: The term seeks to capture the uncertainty regarding one’s own capability, adversary capability, and adversary intent during an engagement, operation, or campaign. This definition is in regards to military operations. However, the definition can be applied to the imposter syndrome as well. Like most psychological states, it makes us see life…
Automating The Arrange Phase With AutoFixture
In a previous article, we refactored a unit test in two ways. The builder and fixture patterns encapsulated an object’s creation, which simplified the arrange phase of a unit test. These two patterns produced a lot of boiler-plate code. It would be nice to never have to create an arrange phase in the first place. AutoFixture tries to produce unit tests with no arrange phase. As the…
Extending The Razor View Engine With View Location Expanders
In a previous post, I dived into view results, and how the razor view engine executes a razor view. Part of the post discussed a feature called view location expanders. An expander does what its name describes. It expands on locating a view within your application, that is, a way to change how your .cshtml files are located. View Localisation A good example of a view location expander, is the…
MSBuild Maintenance Made Easy With Shared Properties
The New MSBuild MSBuild is the build engine for .NET and Visual Studio. It is written in such a way to be composable, allowing you to combine project files. If you have ever used Visual Studio, then you have indirectly used MSBuild. When you open Visual Studio, it is using MSBuild to restore, build, and manage your projects. Recently, a new version of MSBuild has hit the streets. This came out…

2 Simple Ways To Improve Your Unit Tests
Over the past 20 years, testing has become a cornerstone of software development. To turn software development into a true profession, we need to create robust, secure, safe, and efficient systems. The simplest tool in our toolbox starts us on this road: the unit test. Like an accountant, the unit test is a fantastic way for us to perform double-entry bookkeeping. The unit test double checks our…
How to Create Bogus Data in C#
Programmers are lazy. We love tools that automate our lives. Why not automate data? A time-consuming but necessary part of a programmers job is seeding data into a database. Demonstrations, load performance, styling, testing, all need a way to generate data. A rudimentary way of doing this is by hand. Spending days, sometimes weeks, inputting data into a system until it represents a realistic…
Trust Your Data, Not Your Mind
When you add decor to your home, previous decor can look worse. You paint one wall a bright blue, but at the same time, the shine of the wall next to it dulls a little. Your codebase is a never-ending cycle of refactoring. Small improvements to one part, makes you see small improvements for another part. Shining a light on a piece of your code, shines problems on code around it.

Making a Master Puppeteer
There are many ways to test a program. From starting miniscule with unit testing, to more grandiose UI testing. Puppeteer falls firmly in the latter category. Puppeteer advertises itself as a Node library which provides a high-level API to control headless Chrome over the DevTools Protocol That is a lot of words. Puppeteer is a walking advertisement of the true potential the Chrome DevTools…

The Wonderful World of Webpack
Webpack is a JavaScript module bundler, or so the blurb goes. This is an apt name for it. However, what I would like to do in this article, is to expand on the true power of Webpack. This article will not explain how to use Webpack. Rather, explain the reasoning behind it, and what makes it more special than just a bundler. Webpack is still a Bundler One of the main reasons for tools like Webpack…

A type-safe REST
In the current age of microservices, we have communication between different processes across a wide variety of hosts and platforms. At other times, we integrate with 3rd party libraries, downloading information and metadata that may be necessary for our current application. On some of those occasions, we need to interact with a REST API. Wouldn’t it be nice if when interacting with REST…

Docker Compose for a Simpler Life
Docker is a tool that allows you to create containers on the fly, allowing you to easily deploy applications on any environment. This blog post won’t give you the in’s and out’s of all that is Docker. Docker is too big to delve into as a whole in one blog post. This post will discuss docker-compose; a tool that runs and synchronises containers simultaneously. I am a windows man…
Sharing Controller and Views in ASP.NET Core
This post will describe how to share controllers and views across ASP.NET Core applications, shared via an ASP.NET Core library. Best practices within the model-view-controller (MVC) world dictate that we should keep our controllers as thin as possible. Controllers should be extracted away from business logic, operational logic, and any sort of decision making. The only real thing controllers…
The Interface Segregation Principle
Why is the single responsibility principle (SRP) so hard to define? From my experience, SRP stumbles people much more than any other SOLID principle. I thought back to my own struggles with the five principles, and thought it would be better to explain SOLID in a different way; or rather, a different order. What is an interface? a point where two systems, subjects, organizations, etc. meet and…
Using IConfigureOptions<T>
The configuration API in ASP.NET core is now a first-class citizen. It is now easier than ever to configure applications within a .NET application. If you visit the main documentation page Configuration in ASP.NET Core it will give you detailed instructions on how to use it. One part of the documentation discusses the IOptions snapshot. This allows you to take a configuration file - typically json…
What is DevOps?
“Are you a software developer that spends hours setting up your development environment? Do you hate the fact that it works on your box but not theirs? Do you have to spend hours setting up other people’s environments to work with you? Does this sound like your job? DON’T FRET! Docker is here!” - Mr. Joe Sales for all things Docker. This is what software development looks…
