Project description:
It is necessary to develop and maintain a crypto e-commerce platform with multi-level access and functionality (client/moderator/administrator parts).

- DevOps: Docker/Kubernetes; monitoring (Prometheus, Fail2Ban, CrowdSec); dynamic mirroring;
Ability to meet the following conditions:
Deployment of nodes for crypto payments (Bitcoin, Ethereum, and other cryptocurrencies);

Work experience and requirements:
- 5+ years in full-stack projects of similar themes described at the beginning. Deep understanding of the development of multi-layer systems.
