John Boyd-Rainey

I coach programmers on how to write better object-oriented Java, C++ or C# code.

I have run courses on this and related subjects in English and German for a number of years and found that a seminar alone was often insufficient.

One arrangement which has proved to be very productive is that I visit you for a day or two on-site at monthly intervals.

You show me code with which you are having problems, and generally I can suggest possible solutions.

Methods are too long
Classes have more than one responsibility
Flags control the program
Classes are poorly designed.

At the very least we have nearly always found one course of action which you can try out before I return for my next visit.

And I can switch into my role as trainer to teach you a pattern or a refactoring technique as required.

The groups have often refactored their code using a projector, discussing pros and cons of our strategies as we progress.

Along the way we uncover bad smells, OO principles and "bad words" (e.g. if, switch, flag, static, return null).

And design patterns often become clearer to the participants because many books and courses don't provide the correct 'triggers' to curb our procedural way of thinking, so theoretical knowledge rarely helps.

A delegate's feedback after the first day of a course was, "Why didn't I have this course 10 years ago?"

There's more about this on refactorIT.eu
