IT Business Consultant at Grupo Pinheiro de Segurança who launched a remote virtual doorman service that increased revenue 15%.

Brazil
Message

At Grupo Pinheiro de Segurança, I built a remote virtual doorman service line from scratch, from feasibility analysis and technical specifications through pricing and service delivery. The service launched and remains commercially active, with a 15% revenue increase attributed to the product.

I currently work in an advisory capacity, providing technical direction and transferring knowledge to the IT team. I also trained interns and analysts from no prior experience to autonomy in ticket handling and systems administration, and reduced recurring tickets by addressing root causes with user guidance.

Earlier, I worked as a Cybersecurity Support Engineer at Rimini Street, triaging vulnerabilities and applying security patches, and as a Mod Contractor at ModSquad, moderating gaming content and supporting players. I’m also a certified instructor who trained more than 50 students, and I hold an Associate Degree in Cyber Defense from FIAP.
