In this book, you'll build a fintech transaction ledger from scratch and progressively transform it into a production-ready DevSecOps platform. You'll also deploy it on AWS. The app processes credit a

If you’ve ever spent two days pulling data out of an APM tool just to answer “how many virtual users should I run in my load test?”, this tutorial is for you. By the end, you’ll know how to derive eve

Building production-grade forms in React can be a painful experience. It's one of the parts of front-end engineering that most developers are uncomfortable with. Usually, you'll start with a simple co

Here's a line from an official document published by the people who run the internet: "Readers who cannot distinguish satire by reading the text may have a future in marketing." This line actually s

Additive manufacturing has evolved into a cornerstone of Industry 4.0 and modern industrial production. Whether it's light-weighting aerospace turbine components, printing custom titanium medical impl

For many developers, the AI workflow looks something like this: write a prompt, get a response, copy what's useful, and move on. This covers a surprising range of tasks, from summarizing a document to

For data science leaders and product managers who are overseeing multi-model gateways, the standard regression approach to measuring model quality is fundamentally flawed. You're running a causal infe

Kubernetes ships with controllers that manage a fixed set of built-in resources: Deployments, Services, Nodes, and so on. An operator extends the same pattern to resources Kubernetes doesn't know abou

You push your code. A few minutes later, it is live for real users. Between those two moments runs a long chain of machinery: builds, artefacts, migrations, health checks, traffic shifts. Every produc

Most SaaS landing pages share the same core sections: a hero, social proof, features, pricing, FAQ, and a footer. And most developers end up building these from scratch on every project. That's repeti

As software developers, we're usually taught to prioritize features like speed, performance, and uptime. When we build APIs, our core concern is making sure data gets from Point A to Point B smoothly.

Before I had ever heard the term "HIPAA audit", I spent three days helping a healthcare SaaS startup fix a single misconfigured S3 bucket. Not a breach — nothing was accessed. But the bucket was publi

Ask someone what a QA engineer does, and you'll probably hear a familiar answer: "They test software and find bugs." It's a common perception, and to be fair, finding bugs is an important part of the

A couple of months ago, I went for a 10K run with three different devices on me. Why? Another long story of review deadlines and my own procrastination. By the time I was done with my run and got back
