Systems Architect with 25+ years of experience designing and engineering mission-critical systems across financial services, credit intelligence, and regulated industries. Throughout my career, I have built large-scale decision systems, distributed data platforms, and real-time architectures supporting credit, risk, fraud, and financial intelligence workloads. My work increasingly focuses on AI Systems Architecture, including LLM-based systems, agentic workflows, model adaptation, supervised fine-tuning (SFT), and the integration of probabilistic AI components with deterministic decision infrastructures such as rules engines, scorecards, pipelines, and event-driven architectures. I am especially interested in hybrid AI architectures that combine probabilistic reasoning with deterministic guarantees, emphasizing reliability, auditability, and system-level correctness inspired by formal methods. My goal is not simply to build models, but to engineer trustworthy AI-driven decision systems capable of operating at production scale in high-stakes environments.
