I’m a senior Data Scientist and Machine Learning Engineer with a proven track record of delivering end-to-end AI solutions that drive business impact — particularly in fintech and blockchain domains. I’ve designed and deployed systems that detect anomalies in real time, forecast complex patterns, and uncover hidden relationships in blockchain networks through graph-based modeling. My work helps organizations make faster, smarter decisions with data they already own. Beyond data science, I specialize in building scalable ML infrastructure and intelligent backends. I’ve architected cloud-native platforms across AWS, GCP, YC and Databricks — supporting everything from real-time inference to long-term model lifecycle management. Using Infrastructure-as-Code and event-driven design, I help teams move faster with fewer operational headaches. I also work at the frontier of AI, applying large language models (LLMs) in practical, production-grade workflows — from autonomous agents to custom reasoning pipelines. The result: smarter products, reduced manual effort, and new opportunities unlocked by generative AI. Whether you’re looking to predict, automate, or scale—I’m here to help you make it real.
