DevOps since 2014. My overall experience can be split into two phases depending on location.
The first phase is in Asia (Shanghai, China). I've worked with American and European companies in Shanghai on long-term contracts, typically lasting 5-7 years. During this period, I focused on building and supporting clients' infrastructure, which included working with various Cloud platforms such as AWS, AliCloud, and IBM, as well as On-Premise solutions like ESXi\Proxmox, and Hybrid setups.
The second phase is in Ukraine (Kyiv), where I work for an outsourcing company. Contracts in this phase have varying lengths, usually lasting one year. The primary focus is migrating a client's On-Premise or Cloud infrastructure to other Cloud platforms. Worked both independently or in a team of up to 15 members.
