About Me
Computer Science graduate and Software Engineer specializing in AI-integrated applications and interactive data platforms. I have led development teams to build tools like SmartApply, an AI assistant utilizing the OpenAI API. From architecting ETL workflows for research datasets to maintaining focus and precision in high-stakes clinical environments, I bring a commitment to reliability and clear, bilingual (Spanish, English) communication to every project. I am currently seeking full-time opportunities in software engineering, AI automation, and data analysis.
