Devops engineer with a bachelor’s degree in CS and 9 years of experience in some technologies and programming languages.

I also have a great interest in systems programming: especially the development in Rust.
Work in areas related to software engineering: kernel/user space, devops, platform engineering, SRE, embedded systems or cybersec

Prototyped and implemented CI infrastructure using terraform as IaC solution. The infrastructure consisted of Kubernetes cluster deployed on AWS Fargate with Jenkins application as a CI system, AWS PCA for TLS encryption, cert-manager for the certificates rotation and dockerhub as a container registry.
Configured in-cluster container registry to incrementally download big images using Harbor and SOCI index.
Prototyped and implemented CI system using Jenkins, Docker Swarm, and HAProxy. Deployed monitoring solution with Prometheus, Grafana and Grafana Mimir. Configured alerting with Prometheus AlertManager and Slack. Implemented SSO authentication using SAML2.0 and GSuite as identity provider.
Deployed self-hosted runners for bitbucket pipelines.
Created and refactored bunch of groovy pipelines for developer and tester teams.
Maintained production and development infrastructures.

Developed Ansible playbooks for upgrade and deployment Confluence instances to the stage and production environments.
Deployed and troubleshooted Bitbucket mirror farm.
Maintained configuration for the Buildbot CI tool.
Developed CLI utility using Python for automatic migration from one CRM system to another (Salesforce to JIRA) in a fairly short period of time.
Monitored the state of servers and administered Linux hosts (authentication, logging, cleanup, provisioning new VMs and containers, networking problems &c).
Administered Atlassian stack (JIRA, Confluence, Bitbucket).

Started as a L2 support engineer in a big data field. Our team was responsible for keeping the distributed data processing clusters up and running (Hadoop, Hive, Impala, Spark, HBase, Zookeper, Apache Kafka).
Learned Linux internals more deeply (Linux PAM, cgroups, systemd, LVM &c) and communicated with customers as an operations team member.
Developed CI/CD pipelines for customers’ applications which exploited big data platform using Jenkins, Ansible, Python, Gitlab and Bash.
Modeled, developed and maintained AWS CloudFormation templates for managing and provisioning infrastructure as a code.
Refactored and evolved existing Ansible playbooks for full infrastructure configuration.
Configured Kerberos security protocol for authentication of services within Hadoop cluster.
Automated standard operations and procedures to reduce manual work and time for routines (using Jenkins scripted pipelines and Python / Bash scripts).
Provided backup and disaster recovery strategies for infrastructure (with AWS capabilities: EBS snapshots, RDS multi A-Z, S3 cross-region replication &c).
Containerized custom application for big data processing using Docker.
