Work Experience
DevOps Engineer
Lifeist wellness
- Set up and configured AWS using best practices. Automated the deployment of AWS EC2 using AWS OpsWorks; set up a custom Chef Cookbooks repository so we can easily re-use and re-deploy instances as needed.
- Set up Jenkins as CI/CD using the pipeline “as a code.” Migrated to Gitlab to have a centralized CI/CD solution (repositories and pipelines all in one place). This migration improved deployment time by almost 30%.
- Set up a monitoring system using the Prometheus server to collect metrics from EC2/ECS and a Grafana server to build the dashboards from the metrics. Additionally, set up alerts to different channels, including PagerDuty.
Operations Engineer
OpSitters
- Designed a new infrastructure cluster that included a full migration to AWS. This migration had an initial AWS set up such as all the VPC components, a VPN, and NAT instance.
- Automated the instances deployment using Chef. Used Knife EC2 CLI tool to bootstrap all the new instances in AWS and Chef cookbooks with different roles and environments to create staging and production clusters.
- Automated the deployment process using Jenkins as part of the infra set up. The Jenkins server pulls all the code changes from a GitHub repo to the staging and production nodes using a custom Jenkins job and a deployment script.

Solution for Odoo
The final solution included several AWS EC2 instances for different "Odoo roles," some of them behind an Application Load Balancer. Several AWS ECS services and AWS API gateways interact with third-party APIs, an RDS cluster, and a few Lambda functions to run cronjobs and/or automated tasks.
