1. Looking back, what was the turning point in your career that shaped your leadership style?

The real turning point for me was surviving a serious train accident back in my university days. Doctors told me I’d never walk or talk again, but I proved them wrong thanks to determination and the support of my loved ones. That experience taught me a lot about resilience, empathy, and never giving up, qualities that really shape how I lead today. I always try to lead with compassion, remembering that everyone has their own story.

2. Moving from one country to another can be challenging. What obstacles did you face, and how did you turn them into opportunities?

Moving from Colombia to France was a huge leap into the unknown. I had to deal with language barriers, cultural differences, loneliness, and being a foreign woman in engineering. But I turned those challenges into opportunities by always learning, building strong relationships, and showing what I could do through hard work. Every move, whether to France or later to Peru, helped me grow, both personally and professionally.

3. What has been the most technically complex project you’ve worked on, and how did you solve its challenges?

Two projects come to mind. The first is my latest highway engineering project, where I helped win the bid and joined the management team afterwards. It was a big deal for the company but also crucial for the country’s infrastructure, it was a massive operation!

The second is a recent experience at Spiecapag, where I managed the biggest tender of my career (and my first in construction I had to switch roles, as Tender Manager, in the middle of summer holidays, with a very short deadline. The challenge was immense, but I got through it thanks to a supportive team and everything I had learned from my previous role in project management.

Honestly, I think solving technically complex projects isn’t just about technical know-how. Teamwork, collaboration, and being adaptable are what really make the difference.

4. In a male-dominated industry, how have you established credibility and influence, and what advice would you give to young women entering the field?

I built credibility by always delivering results, even in tough situations, whether that meant working through two pregnancies, managing bids, or leading international projects. I’ve faced discrimination and setbacks, but I’ve also built influence by staying true to myself, being resilient, and staying committed.

My advice to young women: find mentors and sponsors, don’t be afraid to speak up, communicate, keep good relationships and remember, you belong in this field just as much as anyone else.

5. How do you balance the technical rigor of engineering with the strategic vision required in project execution and business development?

It’s all about having two mindsets: one that’s detail-oriented and precise, and another that can see the big picture. My engineering background gives me the technical side, while my experience in business development and international projects helps me connect those details to bigger goals. I’ve learned to switch between these modes depending on what the project needs, always keeping the final impact in mind.

6. What personal values or habits keep you motivated, and where do you see the greatest opportunities for innovation in pipeline technology over the next decade?

Family, resilience, meaningful relationships, and a clear sense of purpose are what keep me grounded. They’ve helped me get through tough times, both at work and at home. I stay motivated by remembering why I started and who I’m doing it for.

When it comes to pipeline technology, I see a lot of exciting opportunities in sustainability (reducing environmental impact) but above all in inclusion. That means not just making space for women and young professionals, but also getting kids interested in what we do and why it matters.

At home, I have two kids (5 and 9), and they’re already very aware and proud of Mum’s work. Their enthusiasm reminds me that inspiring the next generation starts with sharing our passion and purpose.
