About Alexandre

I help companies quantify and reduce their environmental impact by building LCA-based tools, sustainability dashboards, and carbon methodologies with a clear product management mindset.

With 5 years of experience across packaging, construction, and waste management, I combine technical expertise (Ecoinvent, ISO 14044, CSRD, Scope 3) with strategic thinking to turn sustainability goals into scalable products.

What I do:

Design and implementation of custom LCA calculators and carbon footprint models

Development of supplier sustainability scoring systems and EcoDesign frameworks

Structuring of ESG and CSRD compliance data for audit-ready reporting

Design of carbon credit calculation methodologies aligned with Gold Standard and ICVCM frameworks (plastics, biochar, circular systems)

Creation of Power BI / Excel dashboards and sustainability tools that teams can own and scale

My mission is to translate complex sustainability data into simple, actionable, and productized systems turning environmental insights into tools that drive measurable impact and business value.
