Intro

I'm a developer, technical writer, speaker and currently SRE.


I started my career as sysadmin, I worked several years configuring and maintaining bare-metal Linux servers. I've also closely followed the arrival of virtualization in servers and later the process of containerization.


During this journey I acquired new skills that gave me the opportunity to work as a software engineer with PHP, Java and Ruby. In addition I worked for a few years with pentest focused on web application security.


Over the years I've kept myself updated and embraced the DevOps culture, working later with Ansible, Docker and Kubernetes. Currently I work as SRE which my main responsabilities are writing Golang system projects to keep the production Kubernetes clusters running.


Besides being confortable with AWS, Google Cloud and Azure. I have also skills with cloud performance and Linux Kernel.

One of the main challenges I had was to implement a new deploy pipeline for the production environment. I did the API migration that was previously in the AWS Beanstalk environment to Docker with Kubernetes.

Later I migrated the same API from Amazon to Google Cloud with GKE.

Another work I did was related to the performance of the main application, when migrating to Kubernetes and doing the tunning work in ElasticSearch impacted on the reduction of infrastructure costs.

I also worked as a DevOps Engineer planning infrastructure and migration between cloud providers using Ansible and Docker.
