Projects: Multitenant shared kubernetes GKE and kubernetes EKS clusters to deploy a SaaS django chatbot machine learning application. Tasks: Apply the GitOps operational framework to the infrastructure automation using terraform to deploy AWS and GCP resources. The app can be deployed in EKS or GKE depending on the value of the gitlab variable “CLOUD”. Deployment of a GKE cluster with three pool nodes for staging, production and complementary workloads. The staging nodes are preemptible virtual machines. Create public and private buckets per each customer stack in both clouds Create k8s yaml configuration definition object files for objects service, ingress, configmap, secrets, horizontal pod autoscaling for the components of the apps. Deploy three cloud sql instances for staging, production and complementary databases Use terraform to implement and configure gcp cloud functions and cloud scheduler to make backups of the databases in the cloud sql instances because the databases created by the cloud sql instance automatic backup feature can be lost when the instance is deleted. Create CI CD pipelines in GitlabCI to deploy the components app in either cloud. Create gitlab pipelines to create or delete a customer stack automatically, e.g creating databases, user databases, passwords, kubernetes objects, infrastructure resources. Create gitlab pipelines to deploy and configure complementary apps like Keycloak and Kubecost Dockerize the django app and related components like Vuejs frontend, Pgbouncer, GCP Cloud Proxy among others. Deployment and configuration of AWS CodeGuru profiler. Deployment of EKS cluster with three EKS node groups or staging, production and complementary workloads. Configuration of EKS autoscale cluster component. Deployment of AWS ES with terraform. Implementation and configuration of gitlab managed apps like nginx controller, certbot and k8s gitlab-runner with terraform. Deploy and configure Rancher. Import EKS and GKE managed k8s clusters.

I have been working for an odoo consulting firm for the last three years where I am the main Cloud Engineer. I have deployed a DC/OS cluster in these cloud providers: IBM, Azure, Google, AWS where I have managed the build and deploy docker images of odoo and PostgreSQL using the Mesosphere framework (similar to kubernetes which can run in DC/OS as well). I know how to use Terraform + ansible. I usually work on a system with gitlab - Jenkins, where I built most of the apps using scripted pipelines and then deploy them to the docker cluster. I know how to use Jenkins and the cluster command-line tools to optimize the use of the cluster resources by autoscaling up and down the number of nodes, and using OnDemand instances for production environment and spot instances for the staging one. I have implemented automated backups of the databases using PostgreSQL client tools and automated snapshots in AWS to store backups in S3 buckets according to a backup plan. I have implemented wall-e backups to store physical backups remotely in S3. I have worked with data persistence configuration in DC/OS to preserve the PostgreSQL between restarts of the docker containers. I have implemented IPsec VPN networks that connect google, aws an azure.
