Sole internal IT owner for 53 endpoints across 12 departments and 31 ERP users; coordinated an outsourced team of 4 (2 technicians, 2 owner-managers). Administered 26+ vendor contracts spanning telecom, security, A/V, printing, cloud, ERP, HVAC, elevators, and CFTV; negotiated terms that held costs flat against annual inflation. Ran the organization’s first-ever IT satisfaction survey (90% response rate); translated findings into email-based ticketing (matched existing user behavior), role-based equipment procurement, and a dedicated internal IT contact point. Owned a ~2,100-item asset inventory for SECULT-MG / Fundação Clóvis Salgado government compliance; identified 8 misregistered items previous administrators had missed, closing an audit-risk gap. Configured and supported the Sankhya ERP (parameters, user access, training); handled ~18 tickets/day; built management dashboards and tracking in Google Sheets. Resolved problems the outsourced IT team could not; escalated only strategic decisions to the financial director.

Co-founded a B2B prototyping venture; built a customer-facing PDF quoting workflow (ReportLab) and researched ERPNext localization for Brazilian tax compliance. Handled production engineering end to end (Bambu Lab P1S): G-code purging routines, PETG/ABS calibration, flow-ratio and K-factor tuning, warping troubleshooting.

Managed building automation: HVAC mapping, sensor monitoring, chiller programming, building-wide temperature scheduling. Coordinated facilities operations and vendors across the concert hall and grounds; triaged ~10 tickets/day across HVAC, lighting, telephony, and elevators.

Ran live audio/visual production for weekly classes (~50 students) and recurring events of 100–350 attendees, including long-shift event days; programmed and controlled lighting systems.

Supported 10+ corporate clients across veterinary, accounting, design, education, and manufacturing sectors (incl. Univet, Workmaster, AcrilMinas), on-site and remote. Planned and installed physical network cabling infrastructure; diagnosed server, security-system, and connectivity failures; evaluated and recommended software solutions per client need.

Managed the lighting system for sermons and theatrical productions in a ~400-capacity venue as part of a 4-person technical team; nearly 3 years of consistent production work.
