## Headline

Backend Engineer @ Inovaare \| AI/LLM Systems \| Python, Java, AWS EKS

## About

Backend engineer focused on building AI/LLM systems into production data pipelines, not just chat layers on top of them\. Over the last 3 years I've rewritten legacy Java systems into cloud\-native Python microservices on AWS, and built a hybrid retrieval\-augmented generation pipeline from scratch, combining dense and sparse retrieval with cross\-encoder reranking and LLM\-hosted inference\. Comfortable across the full backend stack \- Java, Python, Node\.js, Angular, Kubernetes, PostgreSQL, MongoDB, but my focus now is where those systems meet LLMs: schema inference, data normalization, and retrieval architectures that hold up at scale\.
