I help the infrastructure team to transform himself to get
the possibility to support all infrastructure tasks and complete
infrastructure migration. Also, I have refactored the same
components of infrastructure like terraform modules and helm
charts for fixing critical problems. I design and implement
infrastructure support plans with maintenance events and
scheduling of change.

The main activity of the project was related to refactoring infrastructure as a code for a set of applications. Key features were implemented in project gitops deployment with ArgoCD as the main orchestration tool. Projects include multi-cluster and multi-data-center and multi-regional decentralization concepts that realize high availability, high readability, and observability.

I have rebuilt and migrated complex legacy multi-account AWS
cloud infrastructure with a set of different development
patterns to single and reliable infrastructure on top of AWS
cloud. We have described all infrastructure resources in
Terraform, Helm, and Docker declarative Infrastructure as a
code. Together with Infrastructure, we rebuild development
workflow to get fully autonomic continuous integration and
continuous deployment process. We have to implement GitOps
with ArgoCD and Gitlab-CI for infrastructure and application
automatic delivery. I have a delivery large impact on hardening
corporate security, data flow, and data processing. This
improvement
decreases
the
complexity
of
existing
infrastructure and as a result cost of ownership. In parallel, I
have work with the Corporate DataLake project that have got
concrete specification and development sprint. Kafka, AWS
Glue, MongoDB, and Snowflake will be the main components for
this ambition Data lake project.
