What I'm looking for

I'm looking to build production machine-learning systems for fraud detection, AML, compliance, or blockchain security, where I can own pipelines from data ingestion through deployment and deliver interpretable outcomes for operational teams.

At Hornet, I serve as the founding ML engineer, architecting an end-to-end AML pipeline for 100k+ blockchain transactions. I build XGBoost and LightGBM risk-scoring models, Go APIs for real-time inference, and audit-ready evaluation workflows using SHAP, precision, recall, and F1.

I also built an Ethereum fraud-detection pipeline that achieved 97.9% bootstrap accuracy with LightGBM, and a multi-agent RAG system using Ollama and LangChain for context-aware retrieval and response generation.
