Clean code
If a chunk of code cannot be understood without reading it 5 times, this should be considered bad code and refactored. Code should read like prose. KISS

Used to think this should be used from a pragmatic approach and only for certain chunks of code but I was wrong and did not understand it correctly. Red green red green red green red green red green red green red green...

Broken windows theory
This kind of relates to clean code as I firmly believe that once dirty code intrudes your codebase, this will often lead to other developers not making enough effort to write clean code around that dirt code which will in the end spread out to your whole codebase.

Seperation of concerns and domain driven design
This leads to simpler code, safer code, more testable code and more maintainable code.

Commit often, small victories, divide and conquer
If you haven't made a code commit by noon, you are probably taking on too much at once. Always go for small victories as this will lead to a more fulfilling development process and better, simpler and cleaner code.

Continuous delivery/deployment will lead to software that can be more reliably released at all time .
Daily standups can lead to interesting coffee break/lunch time discussions but should be kept to the point, not just "I've added this and that".
Regularly, time should be allocated to reflect, should some code be cleaned up, can we improve a project from things learned in another project, are there certain "annoyances" in the development cycle that can be improved, ...

I am a realist that above principles will not always be possible to follow as we don't live in a perfect world and sometimes deadlines just have to made. Yet I do believe that if they are used from the start, at all times a best effort is done and periodically time is allocated to clean up, this will lead to faster development cycles, less bugs and better maintainable code.

An overview of technologies, languages, frameworks, ... I have worked with over the years. Obviously some might be a bit further down in the back of my head but it's still in there somewhere :)
I have grouped them a bit together per domain.
