Hi district0x,
I was one of the reviewers for the district0x contribution contract, and am an active developer in Solidity, web3 and related technologies.
I am London based and a native English speaker, very active in the Ethereum community and with excellent commercial and academic qualifications:

I have contributed to the OpenZeppelin standards and am familiar with the ENS contracts (I actually met Nick recently at an Ethereum meetup in London where he was presenting ;-)).
I have worked with several blockchain organisations, both in a technical, development and advisory capacities - I am happy to provide references from these organisations on request.
Please let me know if you have any queries or want more information on any items.
Thanks,
Adam
