Each row is a skill, each column a year. Colour builds up with experience: every role adds its weight for each year it was held. A ring marks a year the skill was in active use; a diamond marks a certification. Hover any square for the roles behind it.
Drag the cards or the year bar to move through time. Each card carries the colour of the country worked in.
Change any text, hide company names, add your photo, and set how heavily each role used each skill, from 1 (touched it) to 5 (it was the job). The page updates as you go. Press Save changes at the top to keep them.
This removes the page and everything stored about it, straight away. It can't be undone.
