I am a software developer based in Cambridge, UK. My work and expertise is focused largely on the STEEM blockchain. I support the growth of the network by maintaining a witness node, by developing applications, and community tools engineered to empower this emerging ecosystem.
I am a Utopian Moderator. I review submissions in the development category.
I am currently the 7-th most delegated account - currently 300 delegators! on the STEEM Blockchain.
Weekly Witness Update
As a witness, I feel it is useful to have a weekly report, which will be produced every weekend at the hashtag #witness-report

And not to mention time and efforts spent on: developing new tools, monitoring and upgrading the witness servers. It is profitable only (especially under such low STEEM price) if you are at Top 50, so please do support me by voting me as a witness or set as a witness proxy. Thanks.
I like STEEM and I do believe the STEEM - that is why I have been spending money and efforts on being a witness and promoting STEEM community via developing tools/applications, providing APIs, helping Utopian moderating work etc.

300 Delegators! Thank you!
Please note that the SP you enter is the final amount to delegate. For example, if you already delegate 10 SP and you want to delegate another 5 SP, you will need to enter 15 SP (instead of 5 SP) in the delegation form.
