I have known @ecoinstant and collaborated on many different projects and initiatives over the last seven year. He and @thecrazygm (who I haven't worked with directly, since Eco is a great project manager) have been super response to my thoughts and feedback during the develop of the tools already mentioned.
Eco has also been my project manager on various pieces of work for Hive SBI over the last few years and some of that work owes it's completion to his untiring efforts to make sure things were moving forward, especially when I was the bottleneck!
