The example below might seem like very simple advice, but I found people across many codebases do not know this.

Introduction In one of the projects I used to work on, we’ve employed CQRS approach with PostgreSQL as a write storage and NoSQL database as a read storage.

Large language models are used widely across the industry these days.

Many articles focus on the benefits of microservice architecture such as the possiblity of independent horizontal scaling of components or reduced cognitive load, due to compact codebase aligned with a business capability.

One of my recent projects was to create software that would automatically generate music based on a predefined set of rules.

I’m usually skeptical about leetcode tasks since this is not something you’ll encounter in your daily line-of-business code.

It has been written a lot about the value of unit testing and still a lot of developers may have witnessed codebases with unit tests being too brittle or rarely discovering actual defects in software.

Recently I’ve investigated autocomplete functionality of our system as there were a lot of complaints that it returns irrelevant results.

I use my side-project KyivStationWalk as a set of my opinionated takes on software architecture.

When interacting with a service asynchronous communication often is a preferred way.

When working with files there are often both APIs operating byte[] and Stream so quite often people chose byte[] counterpart as it requires less ceremony or just intuitively more clear.

Recently I’ve been tasked to provide date in a specific format from backend to the frontend and I’ve noticed a behavior that I’ve found a bit odd. private static void OutputDateInfo(string value) { Console.WriteLine($"Input: {value}"); if (DateTime.TryPar…

In case one wants to retrieve files from catalog Directory.GetFiles is a simple answer sufficient for most scenarios.

Working with multimedia is terra incognita for most of the developers since it’s something that one rarely encounters while working with usual business applications.

In my experience, the main thing to do in order to improve application performance is to reduce the number and duration of IO-calls.

Introduction While the article title may sound controversial as there is clearly nothing wrong with using string in your code below I’ll show the case where string type doesn’t clearly communicate all the necessary properties of a domain in question.

When I was playing around with my pet-project Kyiv Station Walk I’ve noticed that manually removing test data is tedious and I need to come up with a concept of the admin page.

Why locking things Microservice architecture becomes widely adopted these days.

Consider this simple code downloading page contents using Puppeteer-sharp. let renderHtml = async { BrowserFetcher().DownloadAsync(BrowserFetcher.DefaultRevision) |> Async.AwaitTask |> ignore let options = LaunchOptions() options.Headless <- true let!
