I'm Rubens Vidal. I build and administer IT environments, connecting servers, networks and business systems to the needs of the people who rely on them every day.
Over 20 years of experience, with a professional background in Brazil and Portugal.
Remote projects in Brazil and internationally · Agreed scope and working hours
Seeking remote projects and roles in Brazil and internationally, with a preference for written technical communication and flexible working hours. Availability, meetings and service windows are agreed for each engagement.
Review of an agreed server or group of workstations. Deliverable: a diagnostic report with evidence and prioritized recommendations.
Assessment of defined components. Deliverable: documented findings and a remediation plan; changes implemented when included in the agreed scope.
Remote support for Windows, account, access and VPN incidents. Deliverable: a service record with a resolution or a documented technical escalation.
Review of available information on servers, networks and services. Deliverable: environment documentation and agreed operating procedures.
Each proposal defines the components covered, access requirements, dependencies, timeline, service window and acceptance criteria.
Building an IT function to support integrated business processes, followed by a similar infrastructure assignment in a manufacturing business under the same owner.
Hired as IT Manager, I took responsibility for an environment with a payroll server, while other processes depended on manual controls and spreadsheets.
I built the infrastructure and recruited an intern to support the IT function. The work included purchasing and deploying servers, workstations, print resources, networking equipment and structured cabling, together with Microsoft security services and Exchange Server email.
Processes became faster and more reliable, with greater integration between departments, changes to administrative workflows and employee training.
My responsibility focused on infrastructure and its administration, including preparing the environment for the business platform and participating in vendor selection. The RM/TOTVS implementation team was responsible for the functional ERP implementation.
I continued administering IT after rollout and completed Microsoft and TOTVS training to support the environment.
The integrated platform covered purchasing, stock, billing and contracts; accounting; finance; fixed assets; fiscal processes; payroll; human resources; and construction project management.
The reported RM modules were Nucleus, Saldus, Fluxus, Bonum, Liber, Labore, Vitae and Solum. The vendor team handled functional implementation and the payroll transition.
Qualitative outcomes included faster, more reliable processes, stronger cross-department integration and changes to administrative organization. Staff training accompanied the transition. No retrospective percentage improvements are claimed.
I later worked on IT infrastructure setup at a gas-compressor manufacturer under the same owner, applying the experience from the earlier assignment to another operational context.
