What I value most and am the most productive doing:

Job combining development with design (UX, UI, datasets, Data Visualisation, JavaScript/SVG/D3/Illustrator/Sketch etc). 

Modern frontend and backend. 
Functional programming.

Clear/transparent business processes or an opportunity to improve ones.

I do my worst at 'cross-browser HTML/CSS' and my best at R&D and structuring things (processes, code planning/refactoring/testing).
