The most amazing...
...project I've worked on included architecting, planning, deploying, and maintaining a Kubernetes cluster on a bare-metal infrastructure with a DR cluster on AWS.
Work Experience
DevOps Engineer
Project Circle LTD
- Optimized a genomics pipeline, reducing execution time by 50% and cost by 2x. Used Prometheus metrics to assess and optimize CPU/GPU instances for each step of the pipeline, resulting in significant improvements in efficiency and cost-effectiveness.
- Migrated a Nextflow pipeline to AWS Genomics CLI, optimized computational tasks for performance, and provisioned infrastructure. Demonstrated proficiency in cloud computing and workflow management.
- Improved the efficiency of genomics workflows by implementing a solution that externalizes the execution of predefined tasks. Created a framework that supports the required functionality, leading to optimized task execution.
- Leveraged Terraform to automate infrastructure deployments. Created Terraform modules for AWS services, implemented IaC best practices, and integrated with CI/CD. This enabled faster and more reliable infrastructure changes.
Systems Architect and DevOps
Leader-Bet
- Owned the architectural design, development, and deployment of the company's systems as a systems architect. Defined system solutions based on the company's need, cost, and required integration with existing applications and systems.
- Researched, identified, selected, and tested technology products required for solution delivery, and established, implemented, and documented the technology integration and migration strategies.
- Built a Kubernetes cluster on bare metal with controllers and etcd on an HA configuration. Automated certificate generation and rotation on master and worker nodes and a node provisioning process.
- Provisioned a complementary infrastructure for Kubernetes: local image registry for image storage, GlusterFS for distributed file storage, and Elastic Stack for centralized logging.
- Planned, tested, and moved part of the company's DR site to AWS. Set up the networking infrastructure from the primary site to AWS DR with VPNs and BGP route propagation.
- Delivered EKS on AWS and moved workloads running on the primary cluster to AWS Kubernetes.
- Set up AWS IAM users, groups, and policies. Provisioned EC2 instances with and without autoscaling and load balancers. Delivered RDS databases,. ElastiCache, and other AWS products.
Systems and Network Engineer
Leader-Bet
- Owned the evaluation of the company's infrastructure needs and then chose, tested, and implemented solutions as a system and network engineer. I also proactively ensured the highest levels of systems and infrastructure availability.
- Planned disaster recovery site architecture and documented the process of building, testing, and migrating workloads from primary DC to DR in case of emergency.
- Built a Zabbix cluster for monitoring and alerting. Added the majority of the infrastructure to Zabbix monitoring. Created custom scripts and dashboards where preconfigured templates were not enough.
- Wrote and maintained custom scripts to increase system efficiency and lower the human intervention time on tasks.
- Maintained security, backup, and redundancy strategies.
Network Engineer
Leader-Bet
- Assessed the needs of a company's networking infrastructure and recommended, tested, and implemented solutions from Cisco, Juniper, MikroTik, VMware, and open-source alternatives as a network engineer.
- Performed daily network monitoring, maintenance, and technical support for internal and external networks.
- Redesigned a portion of the company's networking infrastructure using a top-down design approach, resulting in improved performance and customer satisfaction.
- Designed and implemented a DDoS mitigation solution utilizing open-source solutions, resulting in significant savings for the organization.
Experience
Kubernetes on Bare Metal
Automation of Infrastructure Provisioning
I automated the entire process, from virtual machine deployment to configuring essential packages and parameters based on the preset architecture.
The new approach reduced the provisioning time to 30 minutes.
