About the Author

Steve Publications

Steve is a technology professional with over 20 years of experience in software development, server infrastructure, cybersecurity, vulnerability research and reverse engineering. He specializes in analyzing complex systems, identifying weaknesses and improving security.

Beyond his professional work, Steve collaborates with researchers and industry experts to create practical technical books covering software development, cybersecurity, cloud computing, DevOps, AI and enterprise technologies. His goal is to help IT professionals, students and enthusiasts develop practical skills through clear explanations, real-world examples and hands-on exercises.

At Steve Publications, we use AI to assist with translation, proofreading and editing but not to replace the research, technical expertise or hands-on experience behind our books. Some authors publish under pseudonyms for privacy or professional reasons.

Every book is written, reviewed and maintained by experienced professionals, supported by a private community of over 420 engineers and researchers. We prioritize technical accuracy, practical value and regularly updated content over mass-produced AI-generated text.

We welcome experienced professionals interested in writing or reviewing books, especially in specialized and emerging technology fields. If you'd like to contribute, contact us with your area of expertise.

We stand behind our work. If a book doesn't meet your expectations, Leanpub offers a 60-day money-back guarantee.
