What should I do to become a better / professional Flutter engineer?
— A Flutter developer
Hi! I'm Majid Hajian , author of the "Flutter Engineering" project . I am a passionate software engineer since 2006, having taken on various roles ranging from developer to architect. I've been a Flutter community leader and educator since 2019. Ever since I embraced these roles, the above question keeps popping up.
Throughout my career, I have worked in various roles such as a backend, frontend, full-stack developer, software architect, and most recently, Head of Developer Relations. Leveraging my experience, I have spent nearly a year developing the "Flutter Engineering" project. I aim to enhance your skills and lead you towards expertise with this project. Through "Flutter Engineering," I aim to share the valuable lessons I've learned throughout my career.
Although I tend to have a logical and analytical approach, which makes me skilled in programming, I am always curious about becoming a superior software engineer. What is the most effective way to design an application's architecture? How can I manage all aspects of app development, not just coding?
Take a look at the "Flutter Engineering" project! I've compiled a book with architectural and advanced content and supporting materials like videos, code samples, a podcast, and a newsletter.
The Flutter Engineering project goes beyond the book, diving deep into software engineering concepts and advanced topics tailored for Flutter app development.
