- Helped to troubleshoot and resolve issues with existing architecture and processes to improve development velocity and reduce operations toil.
- Automated infrastructure deployments to support on-demand resource provisioning in regions closest to the end-customer to minimize latency.
- Upgraded an existing CI/CD workflow to reduce build failure rates and support multi-region deployments.
- Optimized infrastructure observability with centralized logging and log-based metrics.
- Improved incident response times by establishing key metrics and configuring alert policies based on them.
- Designed a centralized identity management solution for edge authentication and access control.
- Provided technical guidance to ensure best practices and to plan smooth migration of existing workloads to containers and Kubernetes.
DevOps Lead2014 - 2018Assembla
Technologies: Amazon Web Services (AWS), Kubernetes, Docker, Logstash, Grafana, Elasticsearch, Etcd, Vagrant, Terraform, Google Cloud Platform (GCP), AWS, Linux
- Led the DevOps team by acting as a facilitator between development, operations, and the customer success teams.
- Supported the physical infrastructure of the running project: kept relationships with providers, vendors and DC crew, and supervised required maintenance tasks.
- Hardened the production system's security, established workflows and procedures, prepared documentation to pass the security/availability principle part of the SOC II security audit.
- Completed the infrastructure automation using Chef and Terraform, unified multiple environments (production, stage/QA, on-premise, private cloud) within the same Chef codebase which improved the Dev/QA experience and reduced maintenance costs for Ops.
- Improved the system architecture for private cloud installations using Docker, Kubernetes, and Terraform.
- Implemented the required changes to the application stack and built CI/CD tooling.
DevOps2010 - 2014Assembla
Technologies: Amazon Web Services (AWS), ASA, Cisco, Hubot, KVM, Ceph, Elasticsearch, RabbitMQ, Bash, Apache, Jetty, Errbit, Monit, CloudFlare, New Relic, Nagios, HAProxy, Passenger, Capistrano, Pacemaker, Jenkins, DRBD, Chef, Ruby, Mercurial, Perforce, Subversion (SVN), Git, AWS, Linux
- Designed and implemented a new bare-metal architecture of a low-latency triple-redundant sharded file system with hot failover, real-time replication, and off-site backups for needs of shared SVN, Git, Perforce, and Mercurial repository hosting.
- Designed and performed the seamless migration of existing customer base (AWS) into the new infrastructure.
- Implemented a CI/CD workflow that allowed the team to safely execute over 50 deploys into production per day.
- Built a bare-metal KVM cluster and developed the required tooling to provide the underlying infrastructure for staging/CI environments.
- Improved the existing monitoring solution—reducing the number of false positives and increasing the retention periods and resolution for historical metrics.
Lead Server-side Developer2007 - 2010Pravo
Technologies: Memcached, Nagios, Sphinx Search Engine, Percona, MySQL, PHP-FPM, HAProxy, Nginx, Apache, Linux
- Built a system of distributed proxies and crawlers to automatically collect and parse more than 500,000 legal documents per day.
- Developed fuzzy-logic-data-collection algorithms for data crawlers.
- Constructed a document-indexing pipeline using Sphinx.
- Designed a simple-and-effective infrastructure-monitoring system using Nagios.
- Created an HA and fault-tolerant MySQL cluster architecture with ring replication and real-time snapshots using Percona and HAProxy.
