Software Engineering Foundations: Designing Modular Web Applications

Building software that lasts requires more than just writing code that works. To create scalable systems, you must understand how to design clean, modular architectures that remain easy to maintain as they grow. This text-based course guides you through the core principles of software engineering, using web applications as a practical canvas. You will transition from writing basic scripts to designing structured, secure, and robust software systems. What you'll learn: - Understand the core concepts of software design, including modularity, separation of concerns, and conceptual simplicity. - Structure web applications using modern architectural patterns and clean routing. - Apply functional programming principles to write predictable and testable code. - Design relational database schemas and write efficient queries to manage application data. - Implement modern security best practices, including secure authentication flows and data protection. - Practice translating complex user requirements into clear, modular software designs. The course begins with foundational software design definitions and terminology before moving into application structure, database design, and security principles. You will progress through written explanations, conceptual breakdowns, and practical code-focused scenarios. This course is designed for aspiring software engineers, web developers, and computer science beginners who want to build a solid foundation in system design without any prior complex architectural experience.
