I build real-time data pipelines, AI/LLM systems, and security tooling for high-stakes, high-throughput environments.
7+ years shipping production systems across data engineering, applied ML/LLM infrastructure, and security, with deep experience in low-latency ingestion, multi-source data reconciliation, and systems that have to be right under load. Most of this was built for blockchain and market-data environments, which forced a level of correctness and latency discipline that's directly transferable to any data-intensive or AI system.
