About Sergio

I help companies and administrations review, prepare, and optimize technical documentation in public tenders for electrical installations.

I work as an independent technical consultant, providing a qualified second technical opinion for city councils, engineering firms, and maintenance companies that need to validate technical, economic, or regulatory decisions before their execution.

My intervention focuses on critical project phases: validation of technical solutions, detection of inconsistencies in documentation, risk analysis, optimization of maintenance criteria, and support for decision-making with real impact on costs and operations.

My methodology is clear and structured: analysis of existing inventories and information (GIS, plans, Excel, reports), identification of critical points, and development of practical, applicable recommendations aligned with regulations and real operations.

I collaborate on specific technical reviews, light audits, report preparation, support for technical teams, and advice prior to tenders or execution, without the need for prolonged contracts.

Profile oriented towards organizations that need senior technical judgment, to detect inefficiencies, or to validate work performed before making technical or economic decisions, prioritizing high value-added interventions.

I usually collaborate on specific technical interventions (project review, documentation analysis, solution validation, or support in concrete decisions), as well as on broader collaborations when the project requires it.

The dedication is adjusted based on the complexity and actual needs of the assignment, allowing to start with limited actions before addressing subsequent phases if necessary.

If you need specific technical support in tenders or electrical project review, add me to your favorites for future processes.
