Work Experience

Site Reliability Engineer

2016 - PRESENT
TumiSoft (Freelance)
  • Provisioned an early version of IT infrastructure for web applications on AWS using EC2 instances, CloudFront, S3, SQS, RDS, and SES.
  • Deployed an on-premises data center based entirely on open-source software, such as Proxmox VE, Ubuntu Linux, pfSense firewall, master-slave MySQL servers, self-hosted GitLab, Docker, Nagios, Traefik, Nginx, and Redis.
  • Performed the infra hardware-layer configuration consisting of three bare-metal nodes working as a cluster with IBM Storwize as shared storage and NAS for backups.
  • Migrated most of the AWS stack to the data center to reduce costs. I improved most of the components' performance and reliability, including MySQL tuning, backup policies, two firewalls in HA, and migration from BitBucket to our GitLab server.
  • Extended and initially improved the monitoring capabilities using New Relic and then migrated to Prometheus and Grafana.
  • Configured CDN, WAF, and load balancing in Cloudflare for all applications.
  • Planned the workload migration from Docker Compose to self-hosted Kubernetes and implemented the secondary data center as part of the disaster recovery project.

DevOps Engineer

2021 - 2023
  • Led the implementation and adoption of Ansible AWX with integration with Okta for SAML auth and HashiCorp Vault for auth and secrets management. This implementation was done for Splunk Inc.
  • Maintained, improved, and refactored multiple Terraform modules, most of them migrated from TF 0.11.x to 1.1.7. Used Terragrunt to provision AWS infra using Terraform modules and pipelines.
  • Maintained and developed new CI/CD pipelines for GitLab CI on different Node.js-based projects deployed on Amazon ECS.
  • Developed HashiCorp Packer templates and CI/CD pipelines for building AMIs using Ansible and AWX as part of the workflow.
  • Developed several Ansible roles, which served as a common framework to integrate playbooks and AWX Templates with HashiCorp Vault AWS auth and Vault SSH signed certificates for all the other existing roles.

  • Ran technical demos of enterprise HashiCorp Vault and HashiCorp Terraform for potential clients.

  • Designed, implemented, and supported reliable customer cloud architectures. Performed cloud governance, supported by automation tools such as CloudFormation, Lambda, Python, and Terraform.
  • Automated internal processes using custom code based on Python, Ansible, and Terraform. Deployed, documented, and troubleshot HashiCorp Vault and Terraform Enterprise for banks and other big companies.
  • Performed knowledge transfer tasks like demos and workshops and POCs about infrastructure as code using Terraform, Vault, Ansible, and CI/CD. Led the internal adoption of DevOps initiatives and culture.

HashiTalks Latin America 2020
I performed as a speaker on HashiTalks Latin America 2020. I shared my knowledge about deploying a 3-node Vault cluster using infrastructure-as-code tools, such as Terraform and Ansible. I ran a live demo of such deployment on AWS.

VM Provisioning Using IaC at Canvia

Created an automated workflow for provisioning virtual machines on VMware vSphere using infrastructure-as-code tools such as Terraform, Ansible, Packer, and shell scripting. The traditional VM provisioning process took between three and four hours, but this time was reduced to 15 to 20 minutes using the new automated process.

Open-source Data Center at TumiSoft
I led the implementation of an on-premises data center using open-source products. To reduce and optimize costs, I worked on the migration of most of the workloads from AWS to the new data center. This project involved refactoring and improving many infrastructure elements and software solutions based on best practices to ensure high availability, resiliency, and good performance.
