I have a rich and versatile experience in the role of Infrastructure Engineer , SRE , Linux administrator , Head of IT Department and System Administration Department .

I was born and raised in a small village, and now my work helps millions of users.

I am looking for interesting tasks in the direction of RnD: to sort out an incomprehensible bug, to bring a "cool thing" to a team that has not been used before, or to write some kind of "life simplifier". I try to automate everything that requires it, and I try to use Ansible as an automation tool. In an ideal world, I want to work with GitHub and GitHub Actions, and use Issues as a task tracker.

You can contact me with a job offer or for advice on any issues related to my interests or my experience.

For communication, write to Telegram: @jtprogru or via alternative communication channels. You can choose the time for an interview or consultation on the Calendly .

Experience

SRE

I am currently helping to create an cloud infrastructure from scratch for a new bank within the Yandex ecosystem. The tasks that I solve have a very diverse direction: from setting up a new server in the staging environment and writing automation scripts in Python, to deploying a new service to the Kubernetes Production cluster and writing my own microservices that solve infrastructure and information security problems.

Ansible, Terraform, Yandex.Cloud, Python, Go

March 2022 – Now

SRE

Worked on the project "Search". Reduced the total number of errors made when working with the SaltStack repository by adding various kinds of checks for SaltStack. Cleaned the infrastructure repository from linter errors - >10k "HIGH" level errors in >3k SLS files. Globally, a lot of internal self-written products are used, the names of which do not leave the company. The total number of servers in the area of responsibility of the SRE team is 5000 bare-metal servers. Bare-metal infrastructure. LXC, Docker and self-written services are also used. He was engaged in the support of high-load services within the framework of the project.

SaltStack, Python, Linux, Gitlab CI

DevOps

NDA

Project work . Helped the development team in the refinement and optimization of CI/CD. Moved the project from its own bare-metal infrastructure to DigitalOcean Managed Kubernetes. Designed and deployed the Production contour in DigitalOcean using Terraform. The configuration of servers and services was implemented using Ansible. All automation developments are left to the development team.

Ansible, Prometheus, Grafana, Gitlab CI

January 2021 - July 2021

Senior System Administrator

Implemented practices for documenting processes/changes/configurations, as well as updated project documentation. Implemented the IAC methodology. Implemented a template repository with a description of the infrastructure for a typical e-comm project of the company on Ansible and the "buttons" to launch automation via GitLab CI. Designed and launched the project infrastructure "SammyBeauty" . The platform withstood about 75k unique users and more than 225rps in the first hour of launch. He single-handedly implemented the "Big-Green-Button" internal project: a template repository with ansible playbooks and roles (roles are stored in the internal GitLab and connected as dependencies via Galaxy) to deploy projects similar to the above from scratch. The deployment takes place by "pressing a button in the web interface" of GitLab. Implemented Terraform to manage virtual machines on the Proxmox internal virtualization system.

Senior Linux Systems Support Engineer

Supported the infrastructure of state and commercial companies. The total number of servers supported is >2000 servers. Troubleshooting CentOS 6.x/7.x. Working with hardware load balancers, as well as with ITU CheckPoint. Implemented MITM at the infrastructure level of one large project. I wrote automation for opening/closing applications in Jira based on triggers in Zabbix . This automation is still actively used and working.

Interests

I am constantly developing in my professional field, learning new things by the example of solving practical problems.

I'm keeping my blog jtprog.ru as a notebook. Sometimes I write down everything there that may be interesting not only to me in the format of compressed "instructions for action". I also have a channel in Telegram Savin Michael aka @jtprogru , in which, in addition to links to my articles, I publish mini-notes on hard- and soft-skills.

To cultivate my Python and Golang development skills, I allocate several hours a week to work on opensource projects for which I use automation based on GitHub Actions.

I have been interested in photography for a long time, but only recently decided to post my work publicly in the Telegram channel Michael behind lens and in Unsplash .
