“The truth can only be found in one place: the code”

Gunnar Siréus
With over 40 years in the tech industry, I’ve had the opportunity to grow alongside the field, working as a full-stack developer with a focus on Microsoft technologies like .NET, Visual Studio, and SQL Server. I’m well-versed in the latest front-end frameworks, including Vue, React, Angular, and Blazor. My work has spanned various industries, from small businesses to large government agencies, and I’ve found fulfillment in crafting practical solutions tailored to each project’s needs.
Beyond work, I’m a husband and father of two daughters, and I enjoy tackling new challenges—both in technology and in life. I approach each project with a straightforward, service-oriented mindset, aiming to build software that’s efficient, reliable, and makes a difference for those who use it.
The Aspiring Full Stack Developer’s Playbook: From AI to Microservices and Kubernetes
Unlock the Power of .NET and Modern Web Frameworks in Record Time!
As a .NET developer, you know that mastering new technologies can be key to staying ahead in your career. But time is always the challenge—how do you learn and apply cutting-edge tools like Vue, React, Angular, Blazor, Docker, and Kubernetes quickly, without getting bogged down by endless tutorials?
Here’s my promise to you:
With this book and the accompanying code, you’ll be able to run complete applications in .NET Core C#, Vue, React, Angular, Blazor, and even orchestrate them with Docker Compose and Kubernetes. You don’t need to understand all the intricate details up front—the code will run on your computer, and you’ll learn by doing. Isn’t that a great start?
How often have you noticed that 80% of your code gets written in 20% of the time, but those tricky 20% of edge cases consume the bulk of your time? This book gathers the “a-ha moments” I’ve encountered over the years and shows you how to streamline your process by solving those pesky coding challenges.
The guiding principle behind this book is simplicity. I firmly believe software development isn’t inherently difficult—it’s often just poorly explained. If you’ve ever been frustrated with convoluted documentation, this book will be a breath of fresh air.
This is not just a book—it’s a playbook. Inside, you’ll find clear, actionable steps to implement modern features like “Authorization with JSON Web Tokens,” “File Upload with Drag & Drop,” “State Management,” messaging, Docker, and Kubernetes. Plus, you’ll discover how to secure your web apps with best practices like Security Headers and NONCEs (numbers used only once).
Even if you’re not an expert on Docker or Kubernetes, the quick-start guides in this book will get your applications running smoothly. You can dive into the details as needed, but the main thing is getting those apps up and running—fast.
As a software legend once said:
“Truth can only be found in one place: the code.”

Reader's Review
It's pretty incredible how some writers need bells and whistles to get their information across. And then there are authors like Gunnar Siréus, who can pack a huge punch and go directly to the point in helping developers level up this skillset with The Aspiring Full Stack Developer’s Playbook: From AI to Microservices and Kubernetes. Siréus's writing is clear, simple, and straightforward. He knows his readership does not need rehashing of the basics and, instead, doesn't patronize us by telling us the basics we already know. When it comes to real guidance, Siréus does an excellent job of breaking down advanced concepts, and he provides real-world examples and hands-on projects. I thought the incorporation of AI for iterative code development and debugging was progressive and kept the work fresh and modern. There's no question that this work will appeal to developers who want to stay current with industry trends and improve their coding practices. This is a solid, well-rounded resource for anyone serious about becoming a full-stack developer. Very highly recommended.
What makes this developer's playbook engaging is Gunnar Siréus's conversational tone, blending personal anecdotes with technical insights. His narrative draws from decades of experience, making complex ideas accessible and relatable. For instance, he compares using AI tools like ChatGPT to guiding an apprentice, offering practical advice on using these tools effectively. He discusses the benefits of ChatGPT for coding and cautions that it does make errors. The book’s thoughtful structure encourages readers to toggle between code and text. Accompanying GitHub repositories allows for hands-on learning, making it ideal for developers who prefer practical engagement. Whether you're exploring Blazor's unique challenges or mastering microservices with NServiceBus, this book offers clarity and direction. Siréus has penned an inspiring and informative resource, motivating developers to innovate while mastering foundational principles. This is not a book to shy away from as it’s written so anyone can understand and learn from it. It’s not a classic textbook with boring instructions. Whether you're an aspiring full-stack developer or a seasoned professional, The Aspiring Full Stack Developer’s Playbook is a valuable addition to your library. I highly recommend it.
As the title implies, The Aspiring Full Stack Developer’s Playbook is a hands-on website design and maintenance guide. Gunnar Siréus is highly experienced in this field and is an international consultant, having worked for high-tech companies in Europe and China. He provides step-by-step guidance on downloading the appropriate software, describing how it fits together and how to avoid its quirks. The book includes screenshots to illustrate the menu options that will be encountered and typical instructions that will be required when setting up systems. The practical advice will save hours of frustration in trying to get new applications to operate. The playbook is packed with technical detail, acronyms, and computer terminology with accompanying commentary. A bonus is that it will be regularly updated to keep track of new developments in this fast-moving industry. The role of AI is also discussed, as well as web security and troubleshooting. This work is aimed at getting new developers up to speed quickly by demystifying the process and providing clear explanations. The author points out that you don’t have to be an expert on software such as Docker or Kubernetes, as the quick-start instructions included will assist in getting applications up and running smoothly. This will prove to be a valuable guide to those entering the field.
The Aspiring Full Stack Developer's Playbook lives up to its name and feels more like a playbook than a reading manual. It's a gem of a book for any software developer or programmer in general. Author Gunnar Siréus draws from experience as a software developer to provide helpful solutions to some of those "tricky code sections" that every programmer comes across from time to time. With clear-cut examples, the book offers a way for software developers to test the applications featured in this book and use them as practical tools to apply in their own line of work. The book is very technical, but Siréus presents each topic and application in an accessible and engaging manner, making them easy for all software professionals to grasp. If you're into coding, definitely grab a copy!
Author Gunnar Siréus has a remarkable gift for explaining technical concepts with extraordinary clarity and accessibility, making complex technological landscapes feel navigable and exciting with smooth and confident writing.
