Freelancer Overview

I’m a geologist and mineralogist with hands-on experience generating and interpreting complex datasets from automated mineral analysis instruments such as SEM-EDS (TIMA) and LIBS (ECORE). My work involves the analysis of multi-layered image data, integrating spectral, compositional and morphological features to support mineral identification of geological and geometallurgical samples for mineral exploration and process optimisation in the mining industry. My skill set includes strong attention to data quality, domain-specific labelling of geospatial and spectral datasets, and team collaboration to ensure accuracy and consistency across outputs. I bring a deep understanding of mineralogical patterns and geometallurgical workflows, helping bridge the gap between raw data and practical training sets for AI applications in earth sciences and materials characterisation. In addition to my technical expertise, I bring a strong foundation in geostatistics, logical reasoning and applied mathematics, which support data interpretation, modelling and quality control across mineralogical and geoscientific projects. I’m proficient in tools such as Python, R, QGIS and CorelDRAW, and am also fluent in English and Spanish.
