Code is read more often than it is written, that’s why keeping the code clean is very important part of creating maintainable and long living system. Consistency, naming rules, commenting habits, function organization, exception handling – all contribute to code readability and quality.
Developers face code design and micro-architecture challenges during every coding day. Designing your code properly from the start is very important. Moreover, every programmer is a designer. Design patterns, code organization principles, dos and don’ts are covered in this intensive 2-day course.
Junior or senior developers who would like to improve their code organization skills.
Students must have at least few years of software development experience.
The course is taught in English (Contact us if you prefer Swedish).
All students will receive course slides as well as demo and exercise code examples.
