SOLID
A compact language for discussing object-oriented design choices: responsibility, extension, substitution, interfaces, and dependency direction.
Robert C. Martin — widely known as Uncle Bob — has spent decades treating software development as a craft: something to practice deliberately, teach clearly, and improve one decision at a time.
A self-taught programmer who entered the industry at seventeen, Martin built a career around a simple proposition: the quality of a software system is deeply connected to the quality of the thinking behind it.
His work spans programming, software architecture, education, publishing, and the evolution of development practices. He is especially associated with the discipline of making code understandable — not merely functional — and with helping teams reason about change before change becomes expensive.
In 1991 he founded Object Mentor, a consultancy known for instructor-led training around object-oriented design and emerging agile methods. Later, through Clean Coders and his writing, he turned hard-won lessons into teaching material used by generations of programmers. He also edited C++ Report and became the first chairman of the Agile Alliance, linking technical practice with the communities that shape it.
A compact language for discussing object-oriented design choices: responsibility, extension, substitution, interfaces, and dependency direction.
Use executable tests to drive behavior, reveal design pressure, and keep the feedback loop close to the code.
Favor working software, collaboration, and the ability to respond to change over rigid ceremony.
Programming is professional work: practice the fundamentals, protect quality, and take responsibility for the design you leave behind.
Martin begins working as a software professional at seventeen — the starting point of a career that would grow alongside modern software engineering itself.
He launches Object Mentor, building a consultancy around design, training, and the then-emerging practices of extreme programming and agile development.
Martin signs the Manifesto for Agile Software Development alongside seventeen other authors, helping codify a new vocabulary for building software in the face of change.
Books, talks, video lessons, and workshops extend the ideas of clean code from a chapter in a book into an everyday professional discipline.
We are uncovering better ways of developing software by doing it and helping others do it.
