Alexandre is a technical operations professional focused on HVAC, building management systems (BMS), and energy-related installations in complex environments.

With an initial background in software engineering and complex systems, he has deliberately complemented his trajectory through hands-on field operations in HVAC and energy systems, alongside an ongoing energy engineering program (CNAM).

This dual background allows him to approach technical operations with both operational rigor and system-level understanding, particularly in environments where reliability, service continuity, and coordination between multiple stakeholders are critical.

He operates primarily in technically complex, constrained, or sensitive sites, where execution quality, traceability, and disciplined operations are essential.

Alexandre’s work is grounded in direct field involvement and day-to-day technical execution.

His focus areas include:

  • HVAC technical operations and preventive maintenance
  • Building Management Systems (BMS) and on-site supervision
  • Coordination with specialized contractors and service providers
  • Observation and understanding of real operating conditions
  • Support to service continuity in high-requirement environments

His approach emphasizes practical understanding of installations, real constraints encountered in the field, and the disciplined execution required to keep systems operational over time.
