RedCodeОбщие сведения
Professional DevOps engineer with a total of nine years of ITexperience and six years of
DevOps experience. Started my career as an Erlang, OCaml, and Cdeveloper but eventually switched to being a DevOps engineer. Diverse expertise on variousprojects in multiple domains - from a small company, Polygon, that produces networkdevices to large telecom companies such as Deutsche Telekom.
In my day-to-day work, my focus is often on automating all stages ofintegration and delivery of products. The products are typically based on Java and Kotlin andhosted in OpenShift and Kubernetes in private and public clouds. I believe in and use GitOps, DevSecOps, and IaC practices. Ifdifferent development teams want additional features, I try to make options for everyone and not forcethem to use one thing. In my free time, I like to write various bots for telegram and YouTubeusing Golang, Bash, or Python.

This project consists of many teams partitioned by business domains, and Icover five teams with around 70 developers and test automation engineers.
My Achievements:

o Installed and maintained the persistence and queue engines (PostgreSQL,Kafka, Cassandra) using Ansible roles to Nutanix or OpenStack
o Wrote declarative pipelines for TeamCity in Bash for microservices and testautomation; applied the GitOps approach.
o Made it easy for developers to manage pipelines using one or moreversioned YAML files in their repositories.
o Translated infrastructure configuration into YAML.
o Actively helped with versioning, QA, unit tests, docker packaging, sonar, artifactory, installation checks and automatic rollbacks, delivery to the overlyingstands, monitoring, tracing, audit tasks.
o Created turnkey solutions for developers to turn on some options manually - canary, feature toggle, certificates toggle, application options via Helm values.
o Ensured that the delivery to production was semi-automatic.
o Implemented functionality for the confirmation by the security department ofall stages of delivery and storage of settings and certificates.
o At the moment, all of the above is in production, delivery (excluding production)is fully automatic.

I was part of a DevOps engineering team that developed solutions for the entire company; we served about 30 groups. We exchanged knowledge with each other, but at the same time, each of us developed expertise in targeted areas. I mainly worked with Keycloak, 3scale, Kong, and GitLab-CI pipelines.
Main achievements:
o Write an infrastructure microservice to replace a 3scale api gateway:
o backend – implemented Kong working in declarative mode
o configurator - Kubernetes operator wrote in Golang with operator SDK thatused deck
o web interface - slightly reworked Konga UI.
It turned out to be many times faster and more reliable than 3scale for thiscompany; at the moment, it is used in production.
During my time at the company, I also implemented the following solutions:
Reintroduced dynamic environments that were automatically created whenparticular git branches appeared
Reimplemented pact contract testing for some teams
Integrate pipelines with Jira
