> AI Engineer @ Coinbase | Specialized in LangGraph & Agentic Systems | Bridging Philosophy, Psychology & Distributed Systems

Location: Greater Phoenix Area, United States
Profile: https://flows.cv/cesarb

I architect autonomous agentic systems that bridge the gap between enterprise data and cognitive intelligence. My path to AI Engineering is rooted in a deep fascination with how systems—both human and digital—reason and act. 

With a BA in Philosophy from UC Berkeley and an MA in Psychology from NYU, I bring a unique lens to distributed systems: I don’t just build chatbots; I design "Agency." At Coinbase, I operate across the entire stack. I led the development of production-grade agentic CX (python) systems and manage several core internal APIs (Golang) that power them. As a contributor to the Coinbase.com ecosystem, I bridge the "Full-Stack AI" lifecycle—utilizing LangGraph for stateful orchestration, Kafka for event-driven distribution, and React/Next.js for high-scale, consumer-facing interfaces.

I specialize in the "hard parts" of AI: state management via Postgres checkpointing, end-to-end observability with LangSmith, and the complex integration of AI into legacy enterprise stacks like Salesforce, Slack, and other enterprise systems. I view every system as a graph, where strategy, resilience, and precise execution are the only things that matter.
