Dear fellow programmers,
I have been in industry for 15+ years. I have been coding for this long as well. Nevertheless my programming speed and problem solving speed is not increasing. If I try to program fast I introduce more bugs and if I do it slow then also there are corner cases which I miss out. I don't think anyone (including me) can say that its because lack of experience. In short how do I improve my programming speed? Needless to mention that I want to improve quality of my work as well.

Thanks
