What I'm looking for

I am looking for a role that challenges me and allows for growth, where I can leverage my financial expertise to drive strategic initiatives and contribute to a company's success.

I am a finance leader with extensive experience as a CFO and Finance Director, specializing in tech-enabled SMEs. My career has been marked by a commitment to driving growth, profitability, and operational discipline through effective financial planning and analysis (FP&A), treasury management, and strategic budgeting. I have successfully delivered over 74% year-over-year revenue growth and achieved a remarkable 15-fold increase in annual profit, demonstrating my ability to implement impactful financial strategies.

In my current role as Director of Finance at Rematech, I have secured significant funding, including a €100,000 equity-free grant and MXN 4 million in private equity, which has strengthened our growth plans. I excel in building financial models, conducting valuations, and developing actionable roadmaps for businesses across various sectors. My analytical skills, combined with advanced proficiency in tools like Excel and Power BI, enable me to provide valuable insights that guide decision-making and drive operational efficiency.
