Deployed and upgraded systems, services, multiple servers, workstations, and network devices across many offices in Brazil as part of an 8-month complex domain migration project that allowed the increasing network availability from 98.5% to 99.8%, and as a result, increasing sales volume through Electronic channels. Also managed another relevant project scoped to rebuild of the VMware production cluster, which increased about 20% the production environment performance of virtual servers and implemented a new virtualization cluster for the DEV and QAS environments.- Performed many domain migration tasks in DNS, DHCP, VMware, SharePoint, Email, File, group policies (GPO), and Backup systems.- Administrated and maintained remote monitoring and management system: updated agent scripts, monitored dashboard and responded to alerts.- Delivered tasks accordingly the daily schedule, reported progress to CWT teams in UK, South America and US; Gathered technical data to measure progress using scripting VBscript and Powershell to gather the data from the network.- Planned disaster recovery solutions and documented processes and procedures related to duties and responsibilities as well as daily checklist and maintenance for all servers and network devices.- Deployed new workstations and servers based in Images and processes.- Updated websites contents and fixed HTML, CSS and PHP coding.

Supported a project based on six-sigma, scoped to implement tablets devices at the ICU department, it allowed increasing the mobility and communication among the medical team, having the primary goal to reducing the time spent with each patient. At the end of the project, the average time dedicated by an employee to treat each patient decreased around 10%, maximizing the number of calls with the same team.Co-led the project delivery to implement virtual machines to a cluster dedicated to the ICU department, through technologies Dell MCC and VMware.Coordinated changes in projects and operations aligned with the change management control board; monitored and controlled all servers, equipment, and network services through monitoring tools such as Nagios and Cacti. Accountable for applications and technologies such as Active Directory, DNS, Exchange, DHCP, TS/RDP, IIS, SCCM, GPOs, File Servers, Windows 2003, 2008, 2012, and Linux.

Documented clients' networks; it allowed optimize the time of identification and problem resolution of emerging failures in the customer structure; and reduce by 20% the time needed for the technical team to identify and resolve calls.- Built domain networks, deployed system and services such as Active Directory, DNS, DHCP, Exchange, information systems, storage arrays, VMware, Linux, Firewalls, SonicWall and DrayTek, Access Point, 3Com, Brocade and Cisco 6500 Switches and infrastructure Cabinet installations.- Take over new clients' network environments, assess and prepare technical plan to improve the client network performance.- Managed application and servers solution, in Citrix XenApps & XenApp servers.- Solved technical issues in many customers' networks onsite and remotely.

- Supported the network, servers, backup routines, and printers being allocated to the client.- Built and implemented new Active Directory, DNS, DHCP, Terminal Server, Linux and BRMA firewalls and file servers, increasing the network performance and users' productivity. - Directed responsible for the client datacenter and its availability; performed daily checklist and maintenance. - Delegated to trainee new technicians, monitor and support their performance.

- Familiarized with Financial Market (Stock Broker), guided to solve issues in critical environments where requires agility in solutions.- Monitored the datacenter availability and performance.- Organized the domain policies and file server structure, raising the user's performance.

- Managed and supported servers, systems, computers, printers and network devices. - Trained users on a internal CRMs called Siga Saúde and GSS- Kept the equipments and supplies inventory.
