Stop Being a Hostage in Your Own Startup.If you are a non-technical founder, there is a silent fear you probably don't say out loud: "What if I'm making the wrong technical decisions—and I don't even know it until the budget is gone?". Welcome to the Black Box. Software failure rarely comes from bad syntax or a crashing server. It starts with Information Asymmetry—when the developer knows something you don't, but you are the one paying the price for it. In this world, true power doesn't lie with the person holding the capital; it lies with the person holding the knowledge. Don’t Get Stuck in Dev-Hell is not a book about learning to code. It is a high-stakes management manual written by Ayman Belrhiti, a Software Management Developer who has seen too many smart founders trapped in a "Hostage Situation". Turn the Black Box into a Profitable Asset Through the Founder’s Compass framework, you will learn to stop acting like a "customer ordering a pizza" and start acting like a "pilot reading the dashboard". The Software Iceberg: Why 90% of your project’s risk is hidden beneath the interface.The "Business Credit Card": How to manage Technical Debt so the interest doesn't swallow your cash flow.The 90% Rule: Mastering the art of saying "No" to protect your runway and your team's focus.Talent Liquidity: How to choose "Boring Technology" to ensure you can replace a developer in 24 hours.

Engineering Foundations: The Pillars of Modern Software CraftsmanshipTimeless Principles and Modern Practices for Building Systems That Last In an age where AI can write code in seconds, the true craft of software engineering is more critical than ever. This book is a mentor-in-a-book for a new generation of developers – those who want to go beyond automation and master the art of engineering. Starting with the foundational mindset of a system thinker and the core craft of writing clean, testable code, this book walks through the core and advanced pillars of modern software systems – from Lifecycle Management, Security, and Observability to Architecture and Design, Reliability and Resilience, Data and Knowledge Management, and Collaboration and Culture. It then explores how AI-augmented workflows, tools, and mentorship shape the future of engineering. You will learn to use intelligent tools responsibly, not as a crutch but as an amplifier for your own reasoning. Through practical frameworks and real-world patterns, you will discover how to build systems that are not just functional, but also scalable, secure, and deeply understandable. Tools will change, but the principles of thoughtful engineering endure. This is not a coding manual. It's a manifesto for thoughtful engineers who want to build things that endure.
