The Code as a Mirror of the Mind: Code is, at its core, the tangible projection of someone’s reasoning

Software engineering is now a crucial business aspect, with code representing a developer's thought process. Code quality reflects the clarity and completeness of the developer's understanding. Errors in conceptualization will manifest as technical debt and poor system performance. The engineer's theoretical foundation, including computer science principles, greatly influences code quality. Strong language proficiency, utilizing best practices, is also essential for efficient and maintainable code. Experience integrates theory and practice, leading to better architecture and anticipation of problems. Even experienced developers have cognitive biases, making code review crucial. Code review is necessary for identifying errors that may have been missed. This process applies collective intelligence, decentralizing code-specific and framework-specific knowledge. Code review promotes reliable and sustainable software development.
