Senior Product Engineer and technical founder with 10+ years turning ambiguous 0→1 problems into production systems: real-time financial infrastructure, AI pipelines, and developer-facing platforms. Most recently as CTO, shipped the intelligence layer for prediction markets—entity knowledge graph (25,000+ canonical entities, 22 automated data connectors), cross-venue arbitrage, real-time alerting, and a B2B API with billing, webhooks, and CLI tooling. Proven across trading stacks, blockchain, AI video, and high-throughput backends (100K+ RPM). Owns architecture and delivery end-to-end, partners with stakeholders on scope and tradeoffs, and applies LLMs in production workflows (NER, entity linking, classification)—for velocity and signal, not novelty.
