Hello, world! I'm
Rodolfo Lopez III
I build scalable data systems, train intelligent models, and craft beautiful web experiences.
About Me
I'm a versatile engineer who thrives at the intersection of data engineering, artificial intelligence, and full-stack development.
With deep experience across the entire data lifecycle — from ingesting raw data at scale to training production ML models and building the user-facing applications that surface insights — I bring a unique end-to-end perspective that bridges the gap between data teams and product teams.
I'm passionate about designing systems that are not just technically sound, but elegant, maintainable, and impactful. Whether it's architecting a real-time streaming pipeline, fine-tuning an LLM, or shipping a pixel-perfect React application, I bring the same rigor and attention to detail.
