Why large engineering orgs quickly hit the limits of GitHub's queue — and what they actually need. Over the last couple of years, GitHub has been rolling out its own merge queue feature. It's a welcome recognition of a real problem: teams need better ways to manage
Best Practices
DORA metrics have become a staple in the world of software engineering management. Initially popularized by the "Accelerate" book and Google's State of DevOps reports, they've become a kind of north star for measuring engineering efficiency. You'll find them referenced in strategy

You push a PR. CI kicks off. Ten minutes later, red. You check the logs. It’s a test that fails every now and then — you’ve seen it flake before. It times out, or throws a weird assertion. Maybe it’s infra. Maybe it’s racey. Maybe you don’
Technical
A few weeks ago, something broke in production. No big deal — we've all been there. I did what I’ve done hundreds of times before: Checked logs, wrote a patch, pushed to a new branch, and waited for CI. Except CI failed. Not because of my change, but

Best Practices
Python is a fantastic language for writing elegant and flexible wrappers around functions and classes. Wrapping functions is a common practice in software engineering—whether you’re abstracting a third-party library, simplifying a complex API, or just reducing boilerplate. However, blindly wrapping functions without proper type annotations is a dangerous

While this approach served us well in the early days, we eventually realized that to scale effectively and maintain a sense of accomplishment, we needed to introduce
In the ever-evolving world of software development, one size rarely fits all—especially regarding project management. At Mergify, we've spent the past year transforming how we work, creating a system that aligns deeply with our values and team culture. It wasn't just about finding the right
As development teams continue to streamline their workflows, merge queues have emerged as an essential tool for ensuring code quality, especially in complex CI/CD environments. However, with a range of merge queue options available, how can teams select the best solution for their needs in 2025? Here’s what
