When you work on an Agile tech company like Shutl there are many things happening at the same time every week. Developers are constantly shipping new features and maintaining the company’s systems working to make clients happy. Sometimes this means adding features, sometimes this means fixing bugs that only manifest on remote corner cases and therefore…
Test Driven Development with Unit tests and Integration Tests The golden rule of Test Driven Development is never write new functionality without a failing test. Yes. You need to start each feature writing a failing acceptance test, which guides your application design and defines application behaviour. While this test is failing, the feature is not…
That technical challenge is coming, and when it does, do you want TDD by your side? A true story A year ago I had no experience with tests. During an interview, I was given the task of writing a method that returns the nth number of the Fibonacci series, without using recursion. I was so excited…

I’ve also had the opportunity to meet people with a solid background in other tech stacks such as Ruby, Scala, Clojure, etc.
Working with a service-oriented architecture has many benefits and here at Shutl we try to take advantage of them. Creating different layers of services allows for potentially smaller, more reusable codebases that are easier to scale and more flexible in terms of the wide variety of technologies that can be used. At Shutl, our services…
One of the recruitment stages at Shutl is a pair programming exercise where candidates pair with one of our developers on adding couple of features to a small web service. One of the features includes adding a markup to the base price.
For some time we have been collecting metrics using Statsd, feeding them into Graphite and alerting on them via Nagios.
