DevOps / SRE / Platform Engineer
5+ years in FinTech (banks + crypto startups)
Open to LATAM & Europe (remote, RU-speaking teams)

I build Kubernetes-first platforms that ship fast, stay observable, and survive incidents.

• Roles: DevOps Engineer, SRE, Platform Engineer
• Location: LATAM & Europe (remote), RU-speaking teams

• Kubernetes platforms end-to-end: provisioning, upgrades, Helm packaging, GitOps delivery
• OpenShift operations: admin, app delivery, and day-2 troubleshooting
• CI/CD and release engineering with strong rollback discipline (Jenkins, GitLab CI)
• IaC and automation (Terraform, Pulumi, Ansible, Python) for repeatable environments
• MVP delivery with production hygiene from day 1: CI/CD, IaC, monitoring, and guardrails
• Rapid prototyping ("vibe coding") and simple ML models in Python (scikit-learn) when it helps an MVP
• Observability that drives action: Prometheus/VictoriaMetrics, Grafana, alerting, on-call readiness
• Centralized logging: pipelines, structure, retention, access control, fast incident forensics
• Databases and HA: PostgreSQL, MS SQL Server, Redis, MongoDB; Patroni; Keepalived
• Blockchain node operations (Ethereum, TRON): automation, monitoring, troubleshooting
• Incident management (from detection to RCA), reporting, and team coordination

• heritage-infra: end-to-end infra pipeline: VM preparation, Kubernetes automation, GitOps delivery, Helm charts, Vault integration
• heritage-cicd: reference CI/CD pipeline with quality gates, security scanning, container builds, semantic release, and GitOps delivery
• heritage-vm-create: Terraform + Pulumi to spin up project VMs fast (with learning materials and explanations)
• social-project: alternative to LinkedIn (startup MVP baseline)
• DB-Interface-childs-policl: C# interface + MySQL DB for "Children's clinic" (procedures, triggers, functions)

I decided to make my infrastructure rollout repositories public. Each repo includes explanation files and learning guides with practical notes so anyone can reproduce the setup and learn from it.

I am strengthening my public engineering work around open infrastructure and platform reliability:

• practical Kubernetes and GitOps examples that can be reproduced by other engineers;
• CI/CD pipelines with explicit quality, security, release, and deployment stages;
• infrastructure-as-code projects with clear assumptions, local validation, and safety notes;
• focused open-source pull requests in Kubernetes, GitOps, IaC, observability, and DevSecOps projects.

Merged upstream contributions:

• Keep contributions small enough to review and useful enough to matter.
• Prefer reproducible issues, clear docs, tests, examples, and security checks over cosmetic activity.
• Respect maintainer conventions before introducing new patterns.
• Track public work through PRs, reviews, release notes, issues, and durable links.

Я DevOps / SRE / Platform Engineer. 5+ лет в финтехе (банки и криптостартапы). Рассматриваю варианты: ЛАТАМ и Европа (удаленка), русскоязычные команды.

Сделал публичными репозитории с раскаткой инфраструктуры (Kubernetes/OpenShift, Terraform, Pulumi, Ansible, Helm, GitOps). В каждом репозитории есть файлы с объяснениями и учебные гайды, вычитанные и дополненные практическими заметками, чтобы это было полезно всем.
