Executive Summary¶
I’m an AI/ML engineer focused on scalable, end-to-end systems: RAG platforms, agentic microservices, and Cloud Infrastructure. I like clean architecture (hexagonal/ports-and-adapters), strong observability, and fast iteration. I’ve built meta-assistant tooling, LLM validation services, and data workflows that turn traces into actionable insights. Previously I improved fleet-matching algorithms and shipped ML on AWS/Azure; today I apply those skills to LLM-native apps that drive measurable outcomes.
