I perform work from the physical server deployment, to the delivery of application server/database. Troubleshooting is one of my best skills as well as the persistence until the desired result is obtained. Management and maintenance of infrastructure and applications are my day-to-day. I have the LPIC, CCNA and OCA certificates. New technologies are natural skills and are assimilated with happiness and easlly. I have skills in all infrastructure like storage (SAN,NAS e CAS), Firewall, IPS, Proxy, DNS and LDAP. I have advanced knowlegde in shell script and good skills in PHP, Python and PL/SQL. In database I have experience in Oracle 11G and 12C, Oracle RAC, Oracle Exadata, MySQL, Postgres and MongoDB. In DevOps I am responsable for management the Openshift cluster, creating and editing quotas/limits, deploy of projects, configuration of GitLab like repository and CI/CD, modification/creation of new dockerfiles, storageclass and much more.
