Progressive rollout, scheduling workflows, and experimentation with just a basic configuration

Dials on an old-school machine

When you build a new feature, orchestrating the actual launch schedule between the Product, Engineering, and Marketing teams can be challenging.

While it seems easy to launch something new, a poorly executed rollout can end up being your worst nightmare.

Always use the right kubectl version for your cluster 🎛

In my company, I keep switching on multiple Kubernetes clusters depending on which project I am working on.

And to make it even more fun they don’t have all the same version (yes we still have a k8s 1.9 running).
A good practice I try to follow is to keep the…

Use the Chain of Responsibility design pattern to modify app behavior based on configuration changes

Boost your productivity with all the tools you need in one place

Assortment of tools

I love working with Go because it is easy to code and easy to build.

But like with all other programming languages, you have to deal with a lot of tooling. …

Let’s improve the performance of our web applications

Assorted items on a coffee table

A cache that periodically refreshes in the background is a common pattern that is used in several use cases, but how can we achieve this in Go? In this article, I will guide you through the concepts behind the implementation to help you understand how it works.

Your back end is a simple YAML file

I absolutely don’t think human/manual QA gates should be involved in between the writing of code and its being live. To avoid breaking things every time and to have an early cutoff system, you should use feature flags.

There are a lot of systems available on the market to manage…
