I believe the answer is:

systems analyst

I'm a little stuck... Click here to teach me more about this clue!

'person could do it' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'organise any messy stats left inside?' is the wordplay.
'organise' indicates anagramming the letters.
'left' becomes 'l' (common abbreviation).
'inside?' is an insertion indicator.
'any'+'messy'+'stats'='anymessystats'
'anymessystats' is an anagram of 'systemsanayst'.
'systemsanayst' enclosing 'l' is 'SYSTEMS ANALYST'.

'this' is the link.

Can you help me to learn more?

(Other definitions for systems analyst that I've seen before include "One helping to create IT solutions" , "one looking to improve operations" , "Professional" .)
