Are you ready to challenge your assumptions, to engage in an honest conversation about your professional fears and desires? Together, we'll come up with a step by step action plan to develop the resources that will take you to achieve what truly matters to you.

Be it your next interview, a career change or a difficult UX or product design project you want to tackle, I'll be by your side to help you grow.

I have a solid track record of coaching almost a hundred professionals. I taught courses and workshops at top institutes and universities in South America and The Netherlands.

I've led UX research projects in e-commerce, fintech, travel, agrotech, and other industries in Argentina, the Netherlands, and the United States for well over a decade, specializing in IT products at fast-paced companies like Mercado Libre (e-commerce marketplace, 300+ MM users) and Despegar (travel, 17MM users).

I love the work that Guillermo does as a mentor, from the beginning I could see that he cares about helping me discover my true worth and is helping me to develop it further, and all this based on a real appreciation of the situation and your talents.
