* In awok.com I led a journey of the transition from the old legacy way of deployment, integration and
hosting processes to new, cutting edge technologies and services. We reached zero downtime during
three consequent years and reduced the risk of buggy code in production. We dramatically decreased
the cost of infrastructure from one to another cloud and optimizing the number and usage of services.
And last but not least, I designed and implemented a multi-CDN approach of delivering traffic to end
users. Service automatically switched CDN for end user based on current traffic quality in his location.
And we reduced the cost of traffic and increased the overall quality.
* Migrated cloud infrastructure nodes from Amazon AWS to Google Cloud Platform. 20+ VMs,
databases, load balancers, log and monitoring systems. Reconfigured CI/CD.
* Configured automation delivery of code to environments using GitLab CI. Set up deployment
environments and configuring CI/CD pipelines for automation. Switched deployment from direct to
CI/CD.
* Set up monitoring and alerting services for applications and infrastructure using Zabbix, Grafana,
Elasticsearch.
* Configured multiple Content Delivery Networks - Akamai, CDNetworks, G-Core, Cloudflare,
CloudFront, Google CDN. Automated invalidations and included into CI/CD process.
* Created ETL scripts (bash) to load transactional data to Google Bigquery.
* Created ELT solution based on Apache Airflow and Kubernetes to load data to external systems
(BigQuery, Google catalog, Facebook catalog).
* Designed and developed RUM (Real User Monitoring) solution to collect metrics from user's browser
using Akamai's open source tool "Boomerang" and stream to Elasticsearch with Logstash.
* Adopted Git flow to specific software development lifecycle. Designed CI/CD and pipelines accordingly.
* Designed and set up "canary" deployment scenario for monolithic PHP/MySQL application.



* Designed several microservices and communication between them using Google Pub/Sub.
* Configured linux servers and applications for environments. CentOS Linux, Ubuntu, Nginx, Apache
