Support infrastructure with tons of AWS services (ECS, ECR, EC2, Route53, Lambda, RDS, VPC, S3..) Modern security approaches with multiple accounts and role assuming. 100% definition of infrastructure by Terraform with custom builds of some providers (bitbucket for e.g). Ansible for complex host configuration. Write additional infrastructure microservices (Python, aws ask) Side integrations with Slack, Bitbucket, etc.

Troubleshooting in performance, scalability and reliability of Amazon Kubernetes cluster. Improving "Infrastructure as Code"-practices in company. Improving monitoring and security systems. Automation for everything. Automation of user and password managing. Support migration from private cloud to AWS. Kubernetes, Amazon EKS, RDS, EC2, S3, Postgres, Microservices, Python, Terraform

Deep-dive into Golang. Started several opensource projects aimed at real-time stocks trading and scalping trading with Tinkoff Invest OpenAPI. Managing Kuberenetes bare-metal cluster based on Rancher Kubernetes Engine and Hetzner cloud provider.

I am involving in the development of various financial subsystems based on RabbitMQ and modern Event-sourcing concept. Technological stack: Kubernetes, Gitlab CI, Ruby, PostgreSQL, RabbitMQ, Redis.

Building and managing complex production system. Building and improving CI/CD pipelines and processes for my team. Integrated several side services in application's stack. Key technologies: Tools/Languages/DevOps: Terraform, Ansible, Consul, Git, Groovy, Ruby, Ruby on Rails, Jenkins Cloud platforms: private VPS, ESXi, KVM, AWS, Docker Swarm Monitoring: Prometheus, Grafana, ELK, Filebeat, Datadog Databases: PostgreSQL (and Postgis), Redis, MongoDB, Memcache

Delivering new features/releases to production Setting CI/CD pipelines, monitoring production nodes, etc. Creating and improving some business parts of the backend system (geolocation subsystem, A/B-testing subsystem)

Achievements: Multi-node multi-GPU mining cluster controlled by Ansible (some parts were written in Ruby) Wrote special GPU stats exporters for Prometheus (open source) Automatic crawler system which parses Facebook and VK groups and makes auto-replies.

I implemented different parts of high load vulnerability detection system, focused on data storage backend which uses a wide stack of components (ElasticSearch, Riak, Tarantool, Redis)

I participated in the development and improvement of a distributed asynchronous system focused on scraping and parsing search replies' data (from Google, Bind and other). Also, I integrated different side-services like captcha resolvers and affiliation programs.
