ABOUT

Architect of operating models and decision systems

I design organizational architectures that connect strategy, governance, and execution in complex environments. I operate at the intersection of digital transformation, education, and impact—translating complexity into clear, sustainable operating models.

My journey

My journey has been built at the intersection of management, impact, and education—with a central axis: structuring systems that sustain decisions, outcomes, and learning in complex environments.

Experience

  • 15+ years as an executive, consultant, and educator.
  • Work in large organizations and high-complexity environments.
  • Impact work and startup mentoring (especially impact-led initiatives).

Specialization

  • Decision systems, governance, and execution.
  • Expertise across process, project, and product management.
  • Fluency in technology, data, and information architecture.
  • Indicators, dashboards, routines, and prioritization criteria.

Where this has been applied

Work delivered in organizations such as Petrobras, Repsol, TOTVS, Endesa, Yduqs, and Médecins Sans Frontières (MSF), as well as in startups and growing companies like Digibee and Estuda.com.
I also supported social projects and social enterprises as a mentor, through programs with Gerando Falcões and EXPO Favela.

1. Foundation: learning how to think

My degree in Industrial Engineering at UFRJ was defining. Engineering gave me a solid base for logical reasoning, scenario reading, decision-making under constraints, and a deep understanding of trade-offs and consequences.

More than methods or tools, I developed a way to approach complex problems without looking for shortcuts. A systemic view of processes—inputs, outputs, interdependencies—combined with a quality and continuous improvement lens, shaped my work from the start.

This foundation enabled a consultant and strategist mindset, with strong observation, analysis, and reflection before action—a trait that runs throughout my professional trajectory.

2. Turning point: impact as a deliberate choice

In 2013, my path shifted meaningfully. I became more deeply involved in volunteer work and connected with TETO, an organization focused on tackling extreme poverty. That experience was a turning point.

It wasn’t just about “helping”; it meant revisiting priorities and criteria for action. From there, I pursued training in impact business, participating in programs such as Yunus Social Business, Recode, and Instituto Quintessa.

In that period, my entrepreneurial drive consolidated around a question that still guides me: how do you structure initiatives that make sense in the real world and remain sustainable over time?

In parallel, I deepened my work on self-awareness and consciousness, recognizing that organizational transformation does not happen through techniques alone. That led me to Gaia Education, expanding my sustainability lens and qualifying me as a trainer.

This human development path made something central clear: methods don’t operate by themselves—people do. From that, I developed a leadership lens oriented toward collaboration, collective intelligence, and the creation of environments where desired outcomes become possible.

In that context, I also trained in the Pedagogy of Cooperation, enabling me as a group facilitator—able to structure, plan, and lead workshops, journeys, and collective processes with meaning.

3. Two tracks that evolve together: corporate and education

While deepening impact and human development, I continued an intense corporate path as an executive and consultant—working under pressure for results, growth, governance, and difficult decisions in structures not always prepared for contemporary complexity.

After completing my MSc in Business Administration (Strategy & Sustainability) at PUC-Rio, education became even more central. I entered formal teaching—undergraduate, postgraduate, MBAs, and executive programs—and never left.

Teaching became a natural extension of practice: a space to organize thinking, exchange perspectives, and translate real experiences into applied learning. Beyond academia, I led educational and training programs for refugees, open courses, and learning initiatives in diverse contexts.

As an executive, I saw clearly that strong outcomes depend on well-structured systems. Based on my experience across processes, projects, and products, I began structuring workflows, governance models, and decision systems that generated measurable results across oil & gas, energy, infrastructure, health, education, and technology.

4. Today: integrate, share, and sustain

Today, my focus is on strategic organizational consulting—working side by side with leaders and teams to design, review, and structure functional workflows that connect strategy to day-to-day execution.

  • Map and reorganize workflows across areas, reducing noise, rework, and informal dependencies;
  • Structure decision systems with clear criteria, defined autonomy levels, and governance rituals that sustain consistent choices over time;
  • Integrate processes, projects, and products into coherent operating models, avoiding method overlap and fragmented effort;
  • Support leaders transitioning from improvisation or excessive control toward systems based on clarity, distributed accountability, and continuous learning.

I’m fluent in technology and data, which allows a pragmatic approach to structuring functional work systems: indicators, dashboards, follow-up routines, prioritization criteria, and the intelligent use of digital tools as decision support—never as an end in themselves.

I work with organizations operating in complex, regulated, or changing environments where generic solutions fail. My role is to help build sustainable work architectures adapted to the real context, the people involved, and the constraints in place.

In parallel, I continue developing independent projects, teaching and mentoring, and maintaining spaces for reflection and listening—so the human dimension remains present in any organizational system.

More than delivering diagnostics or frameworks, my work is to create the conditions for organizations to decide better, work with more clarity, and sustain results over time.

“The most empathetic manager I’ve worked with—broad experience with an excellent technical level.”

“I grew a lot working with you. At times you believed in me more than I did.”

“Knows how to listen and support people’s development.”

“Mediation, relationships, and process structuring: broad view with a clear step-by-step path.”

“Works toward collective awareness and improving the planet, in many dimensions.”

“Communicates well, leads teams well, and navigates authority effectively.”

Principles

  • Decision before method — tools help, but criteria comes first.
  • Governance as a system — roles, cadence, and accountability reduce ambiguity.
  • Execution follows design — recurring issues are usually structural.
  • Metrics as support — indicators inform choices, not decorative status reports.
  • Structures that sustain — focus on autonomy, not dependency.
