About

Hi, I’m Santiago Díaz, a seasoned software developer with 8+ years of experience delivering high-quality, efficient, and scalable machine learning and backend solutions across industries including agriculture, FinTech, and AI. I have deep expertise in Python, sklearn, SQL, NoSQL, and cloud computing services, and I’ve led AI-driven projects for global clients. I thrive in challenging, fast-paced team environments and I’m committed to delivering robust, scalable results through clear communication and disciplined development lifecycle.

My comprehensive experience spans the full ML project lifecycle—from data acquisition and feature engineering to model creation, quality assurance using appropriate metrics, and deployment across diverse environments. I excel at collaborating with cross-functional teams, maintaining a sense of urgency, and delivering efficient, measurable outcomes.
