Profile
Data Engineer and Researcher building scalable data architectures and intelligent, self-optimizing systems. I sit at the intersection of large-scale data engineering and applied AI research — currently advancing Agentic AI that couples LLMs with Reinforcement Learning to make autonomous, data-centric infrastructure decisions. Proven ability to build strong relationships, mediate Engineering with Business, and lead teams managing complex data in international environments.
