Start-up development - from idea to production (1.5k customers per day).
I worked in startups where used cryptocurrencies.  Developed web games based on various blockchains for working with tokens (as game currencies) and NFT (game items).  I was mostly alone in the backend team, so I myself developed the architecture and chose the necessary technology stack.  I also performed the role of devops, used GCP as a cloud, deployed everything on Kubernetes, usually used Postgresql and MongoDB as databases, and also used Apache Kafka.  I used Python and Shell for scripts. Also participated in the development of game mechanics
