Nice to meet you :)
I'm a software engineer.
I have a strong interest in destructive innovation in various sectors based on crypto and blockchain.

I believe business value is more important than perfection as an engineer.
We can achieve optimal architecture with a great understanding of the domain rather than the technology itself.
I think that software development is similar to gardening. It doesn't always have to be kept perfect, but it shouldn't be left messed up for a long time.
We should share issues of the codebase and the organization honestly and resolve them continuously.
I believe that management and leadership have a tremendous impact on the productivity and retention of engineering organizations.

Thanks!
