Profile Summary

I am a Freelance Data Scientist, Statistical Programmer, and Consultant with extensive experience delivering high-impact solutions for diverse clients across sectors. As the founder of Ventis Analytika, I developed an FX prediction tool that optimized financial decision-making, leveraging machine learning models and quantitative risk analysis to provide actionable insights for investment strategies. This entrepreneurial venture showcases my ability to design, build, and deliver tailored solutions that meet client needs. For the Joint Research Centre (JRC) of the European Commission, I collaborated as a consultant on the TES Project, mapping digital ecosystems across Europe and globally. My contributions included designing advanced data pipelines, normalizing datasets, and creating dashboards to visualize knowledge flows, enabling stakeholders to make data-driven decisions. I have also consulted on regional economic modeling projects for ECLAC, enhancing value-added assessments for multiple countries, and supported fraud detection initiatives at Banco de Venezuela, reducing fraud in credit products to zero. Proficient in Python, R, SQL, and tools like KNIME, TensorFlow, and PowerBI, I specialize in machine learning, data engineering, and advanced analytics. I offer expertise in designing ETL pipelines, developing statistical models, and solving complex data problems. My collaborative mindset, problem-solving approach, and adaptability enable me to deliver exceptional results, whether for individual projects or ongoing partnerships. Currently, I seek freelance opportunities to help organizations tackle their data challenges, innovate processes, and achieve their goals with confidence. My focus areas include financial analytics, healthcare research, and sustainability projects. Let’s connect to explore how I can support your next big idea!
