The Effective Software Engineer guides you from clean coding habits to organizational empowerment, bridging the gap between developers and leaders.
Spring Boot 4 changes everything you thought you knew about building Java applications. Virtual threads make blocking code fast again. Native images deliver instant startup. First-class API versioning finally solves the "how do we evolve our APIs?" problem. But here's the catch: upgrading isn't just a dependency bump. Jakarta EE 11, new auto-configuration patterns, GraalVM constraints, and reactive vs. virtual threads— getting it right requires understanding the *why* behind every change. This book is your production-ready guide to Spring Boot 4 and Spring Framework 7. Written for intermediate developers who need more than "hello world" tutorials. Learn how to: • Build cloud-native microservices that scale • Migrate from Boot 3 safely and incrementally • Design APIs with built-in versioning and resilience • Choose between reactive, virtual threads, and native images • Secure distributed systems with JWT and OAuth2 • Implement observability that actually helps you debug production issues 300+ pages. 27 chapters. Real code. Real architecture. Real problems solved.

Fifty RF‑101 Voodoos arrived in Vietnam. Forty‑seven were shot down in a year. The pilots who survived didn't fly faster aircraft — they cycled through the OODA loop faster than the missiles chasing them. Jeff Sutherland was one of them. He went on to co‑create Scrum. Now, six decades later, he is running AI agents through daily sprints at machine speed — and this book is the playbook for how to do it without getting shot down.

We're authors too, and we built Leanpub to be the platform we would love to use. It turns out, we weren't alone...
As an academic, I like Leanpub because it lets me write and get my ideas out there quickly. Leanpub is simply the best place for publishing my books.
Leanpub's book-creation tools allowed me to focus on creating the types of books I wanted to write instead of worrying how to create my own book publishing toolchain. I have never regretted using Leanpub to publish my ebooks.
Leanpub takes the pain out of publishing. They provide the tools, you provide the books and then magic happens.
I love using Leanpub because I can write my book using simple Markdown notation. Leanpub let's me focus on my content and they handle the rest.
Leanpub is a game changer for independent authors, removing the hassles associated with formatting, book production, and electronic sales, freeing up the time to do what we do best: write.
Leanpub helped me achieve my goal of publishing a book. Its simple, easy to use interface got my book up and making money within weeks, I love Leanpub!
Leanpub helped me gauge interest in my book, get payments early on when it was only a few chapters, and has got me a bunch of sales just from people browsing around the site.
Leanpub helps me see my books as I write them. Even better, I can find readers early, to read my books and offer suggestions. I can pivot, if I see the need.
Leanpub made it simple for me to run with my book idea and build my reputation in the Ruby community. I went from first draft to first sale in days, not months or years.
Four years ago, I joined Leanpub to just give it a try. Today, over 28,000 book sales later, I cannot help but say that I'm the biggest Leanpub fan on this planet!
Leanpub makes publishing your own book super easy. The fact that you can release updates continually helps with the mindset of getting a minimum version out ASAP and then iterating to improve.
I earn more royalties from my books on Leanpub than I do with well established publishers or through Amazon (which I publish on thanks to Leanpub's mobi conversion).
Leanpub allows me focus on content, takes care everything else and offers an amazing author royalty. It’s a fantastic platform for writing and publishing books.
I love that Leanpub makes writing and publishing a beautiful book so simple. I no longer spin my wheels with layouts and formats - Leanpub gets out of the way when it's time to write, and then automates everything when it's time to publish.
With Leanpub, the first person who purchased my book for $9.99 almost two years ago (and only received a preface, and two short intro chapters) has had access to almost every bit of knowledge I've gained in those two years, and *that's* the value.
Simple and lean, forces me to focus on writing and marketing, and pays excellent royalties.
Leanpub forces you to focus on writing and gives you immediate feedback. Allowing Leanpub to take care of the curation and delivery helped me focus on shipping my book.
While most eBook exporter apps today can generate PDF files and many support ePub, there's one tool we recommend above all after trying 8 of the most popular: Leanpub.
