SUMMARY

I'm a passionate Devops engineer with 8 years of experience helping to migrate and build cloud applications using technologies like AWS, Linux, Docker, Terraform/Cloudformation and CI/CD pipelines following security and performance best practices. I have taken part in devops teams managing the entire cloud infrastructure in AWS from the creation of highly available and scalable environments, to the management of all of its components and also involved in the creation of CI/CD processes to build. test and deploy code from development to production environments in servers, docker containers and serverless architectures. As an engineer I'm always looking for challenges, learning and improving my skills to be on the cutting edge of new technologies
