    Over 15 years experience in IT, started my career in 2004. 7 years as a lead network engineer and head of tech support in local ISP. Built and managed a highly available IP/MPLS network with over 40Gb/s peak upstream traffic, capable of providing L2/L3 VPN services with QoS, as well as IP transit for other ISPs and subscriber management for broadband users. Personally hired and trained team of engineers, who are now capable of further development and support of the mentioned network. 5+ years as a system engineer and architect in a public/private cloud and IT services business. Built and maintaining highly available Openstack/CEPH cloud based on Canonical Openstack. We're providing our customers with general VPS/cloud services as well as custom IT solutions. This is my primary occupation at the moment. I mostly work with environments based on Linux(Ubuntu, CentOS): configuring monitoring, alarming, and billing services for continuous business operations. I'm good at learning new things, as well as teaching other people my trade.

    Hello, I'm ready to help your business implement a DevOps culture, including building a CI/CD pipeline, CloudOps administration, Dockerizing, and monitoring. With over 12 years of IT experience in automated infrastructure administration, maintenance, and support, I have worked on projects with approximately 50 application stacks and in growing startups, helping to implement the best solutions. My main stack experience includes: • Implementing CI/CD with Jenkins Pipelines of any complexity. • Dockerizing applications and deploying them to Kubernetes clusters or AWS ECS-Fargate clusters. • Configuring AWS ECS Fargate clusters. • Setting up Kubernetes clusters on bare metal for local infrastructure. • Updating infrastructure to utilize more flexible resources (e.g., using AWS Auto Scaling groups instead of single EC2 instances, employing application load balancers instead of classic ELBs, updating to use Terraform 0.12). • Starting developer stacks on spot EC2 instances instead of on-demand. • Migrating AWS resources such as S3 buckets, EC2, and RDS to other AWS accounts/regions. You will receive a fully automated CI/CD setup in a VM with Jenkins installed and configured to integrate with the SCM of your choice, such as GitHub, GitLab, or Bitbucket. The configuration includes the following: 1. Installing Jenkins and the required plugins for SCM integration. 2. Creating a job/pipeline and configuring it to fetch the latest code from the repository whenever a commit is pushed to the repo. 3. Configuring Jenkins to push the build output (artifact) to a target server (e.g., FTP, SFTP, SSH). 4. Setting up email notifications upon completion of the build (success/failure). 5. Enabling SCM to notify Jenkins of commits/merges into the master/develop branch. COMMON CASES: CI and CD for web servers: • Developing CI pipelines integrated with GitHub, Bitbucket, GitLab, or other Git sources. • Integrating CI pipelines with SonarQube. • Developing CD pipelines integrated with CI and machine instances. • Implementing user-based access control. • Recording deployment history details. • Setting up Artifactory to store packages. • Integrating CI with unit testing. • Integrating CD with sanity and regression functional testing. CI and CD for Android Applications: • Integrating CI with SonarQube. • Setting up CD to generate APKs for uploading to any artifact repository. • Integrating with unit testing. • Automating functional testing across multiple devices. 🔑 Keywords: AWS, EC2, Elastic, S3, Azure, Docker, CI/CD, pipeline. Don't hesitate to contact me.
