Hi, my name is

Rey Estrada

DevOps Engineer, Techie guy and a Bad Gamer

I’m really good at finding stuff others struggle to find. Sometimes, I’m not a bad gamer =)

About Me

With many years of experience (depending from where I start counting), since I always was very curious and autodidact, which is part of my inner self. Since when I was 13, in 2001, when my mom told me not to touch the computer because the disc drive was not working and I fixed it with no manual, no youtube and no internet, just curiosity. With a diverse background, that goes from QC and QA, passing through SysAdmin, and now DevOps Engineer. I have worked with many people remotely from around the world which has been a great experience.

Here are a few technologies I've been working with:

AWS
Linux
Terraform
Ansible
Git
Docker
Kubernetes
Jenkins
Datadog
Python
And many others..

Experience

OneCloud Systems
Tripwire
Evolve Media, LLC

DevOps Engineer - OneCloud Systems

2018 - Present

In this company I have worked with different clients from different industries and using different technologies, with people from around the world, remotely.
I help customers to create, maintain and improve their infrastructure. Work with developers to create good pipelines.
Set up infrastructure mainly using Terraform but I also helped create and maintain infrastructure in CloudFormation.
Setting up CI/CD pipelines using mostly Jenkins, but I also was involved with CodePipeline, GitHub Actions and a little bit of BitBucket Pipelines.
Used Packer to create an AMI. Packer calls Ansible to provision the instance and then Terraform uses the resulting AMI to create the infra with an ASG ready to self heal and scale.
Combined a Jenkinsfile to use custom containers, using Dockerfiles to run the jobs.
Created a python script that was intented to be a helper to connect EggPlant to Jenkins, that way we could grab the resulting PDF files of an EggPlant execution (QA Tool) and save the resulting files as artifacts right into Jenkins, which happens to run right after a build job.
I have downsized a manually created Kafka clusters, which were runing overprovisioned in EC2 instances after part of the company was sold/migrated.
Participated in onCall rotations to help fix issues in production environments right when they happen. I have the knowledge, but I’m not willing to do it anymore, but if an issue happen when I am in front of the computer I will be happy to help, even if it’s not my working schedule.
Scrum and Kanban methodologies have been used depending on the client.
