Experience
Migration from ECS to EKS
We had a challenging timeline and uncharted territories to migrate from ECS-based workloads to EKS, in alignment with the rest of the company's mandate. Implemented a comprehensive Terraform and Helm-based infrastructure for multiple microservices of the team. Rapidly brought the team up to speed with the Terraform and Kubernetes ecosystem and troubleshot any problems that arose during this transition.
Migration from Heroku/Hetzner to AWS/Yandex
I built infrastructure from scratch to facilitate migration to AWS and increase redundancy and agility. This was a project that targeted the firm's PL, ES, and RU markets. This project spanned about 15 months, covering a web of complex monoliths that were broken down into multiple microservices in order to transition to a containerised ecosystem with ECS. The migration dramatically increased our velocity of deployments and the scope of infrastructure monitoring and optimized our costs directly based on the consumer request volume.
Baremetal Kubernetes Operations
http://riskident.comI performed comprehensive disaster testing for a bare-metal Kubernetes infrastructure. I also implemented MongoDB backups and restoration for the in-cluster MongoDB. I conducted extensive disaster recovery and testing as well as documentation. I implemented LUKS volume encryption and decryption for Kubernetes member nodes.
