• I am currently Chief Technology Officer at Aidyia Limited, a Hong Kong-based artificial intelligence-driven financial technology company.

    I’m a entrepreneur, running a consulting and outsourced R&D company in Brazil. I’m also a researcher in artificial intelligence and so-called data science, and its applications to computational finance, bioinformatics, and other domains. This site includes explorations in data analysis, learning exercises, pointers to open source code, and lessons learned during my research and work projects that I thought worth sharing.
