Short personal pitch

As an industry practitioner, I want to help craft "lighter" Hyperledger DLT technologies - designed for high Throughput systems -  like Burrow or Iroha  - to be more production-ready.

Having had a bad experience with an Iroha roll-out for, I was quite frustrated as the initial value proposition was promising: a DLT with decent response time, geared towards mortal developers (smile)

So I want to bring to the table my expertise in software architecture, data engineering, and the privileged insights that I have as a major eCommerce / marketplace operator, so we can make this dream of light DLTs for the masses happen (smile)
