    "summary": "System engineer oriented to opensource software and great enthusiast about Puppet architecture and Amazon AWS cloud. In the last years, I started to deepen my interest on provisioning, immutable servers, application performance, continuous integration and continuous deployment.\n\nThank to tools like Vagrant, Puppet, Hashicorp Packer, Hashicorp Terraform, I began to move from my confidence zone in classic system engineering to Devops themes, that I feel much more interesting, exciting and better match my passion and curiosity.\n\nI began my career developing Java-based architectures, today I am working on a PHP-based distributed architecture, with Amazon AWS autoscaling, MongoDB replica sets, in a business-driven reality that requires much more availability of services and responsiveness of monitoring as well.\n\nIn the last years i started to deep containers and containers orchestrator, that perfectly match with distributed architectures and microservices. I moved to Kubernetes my attention and effort  in order to dig as much as possible its objects. For the sake of security i also  started using Hashicorp Vault inside Kubernetes that massively has increased security giving one super safe entrypoint for all application secrets on one side, to the other the chance to develop internally dynamic secret engine for handling custom generation of secrets. Further I focus my studies around the container orchestration and Kubernetes, initially under the delivery prospect. While I was learning this, I've started developing in golang my first microservices around Kubernetes, understanding even way more thanks to the previous experience. Because of that, i discover to be really enthusiast to have moved to the software development around Kubernetes products because the conjunction of the devops skills and the golang development was a great combination in term of efficiency.",

For this reason i move to an nginx reverse proxy with in uwsgi_upstream (we have 100 developed in python) the service company that enables the routing mesh round robin feature of Docker Swarm mode.\n- monitoring: i was used to work with Sensu, but with a docker cluster orchestrator currently is not well integrated, neither with CAdvisor neither with docker api. For this reason i moved to Prometheus that is a time series database with alertmanager integrated that supports docker api out of the box .\n- pipeline and continuous deployments: Jenkins 2.0 with on demand ec2 instances for the unit tests environment, a stable environment with cluster for integration tests and behavioural tests.\n- Puppet provisioning of cluster nodes: the management of the cluster is handled by Puppet that provision and configure nodes.\n- Packer: used for generating provisioned EC2 AMI so the join to the cluster since the come online are as quicker as possible. \n- Development environment: totally managed by docker-compose.",

Created also a pipeline for most critical role servers with Puppetlabs beaker-rspec for acceptance testing puppet code on every commit thanks to GoCD Thoughtworks github hooks. On the IT environment created the same behavior of the production autoscaling (that allow in the integration testing with behat, to scale up webserver before Behat starts ) modifying the AutoScaling group properties with ruby aws-sdk development. Thanks to this task, we are able also to predict pretty accurately how long the autoscaling process and the puppet provisioning take,  in order to setup the new ec2 instances operationals and in service by the elastic load balancer. Measuring and analyzing  these iterations, me and my collegue Simone were able to optimize the provision process, integrating most of the puppet catalog execution directly in a custom AMI thanks to HashiCorp packer tool.",
