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.

Experience
HashiTalks Latin America 2020
https://www.youtube.com/watch?v=1a2Lsjn3Fr0I 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
http://www.tumisoft.comI 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.
