A proud contributor to the Crusade of Answers -- more info on meta. We are recruiting: just visit the chat room. :)

A mathematics enthusiast caring to help others out. My most knowledgeable areas are logic and category theory. Additional topics of interest are algebraic topology and set theory.

When applicable, in the process of answering/helping out, I point people to the community effort ProofWiki which catalogues and rigorously founds proofs in all areas of mathematics.

I am not a native speaker of the English language; please feel free to point out any errors.
