Senior Software Engineer at Tellius | Building RAG & LLM-Orchestration Systems (LangGraph, Qdrant, Multi-Agent Retrieval)

About

I'm a Senior Software Engineer at Tellius, where I design and build the AI infrastructure behind our decision-intelligence platform — from production-grade Retrieval-Augmented Generation (RAG) systems to autonomous quality-monitoring agents. Most recently, I architected and independently built tellius-health-agent, an autonomous service that auto-discovers a customer deployment's data and configuration and runs automated + LLM-judge evaluations across five capability areas (Text-to-SQL, RAG, routing, MCP, regression) — cutting manual QA effort from hours to minutes and shrinking failure-detection time from customer-reported (days) to a nightly cycle. Before that, I led a cross-timezone team of 3 engineers to ship a production RAG platform spanning 5 enterprise document sources (Google Drive, S3, GCS, Azure Blob, SharePoint), combining custom Airbyte connectors, Mistral OCR, Airflow-orchestrated hybrid Qdrant indexing (BM25 + SPLADE + Dense), and a LangGraph multi-agent retrieval service with RRF fusion and cross-encoder reranking. Earlier in my career at Tellius and at Lam Research, I built backend APIs, ETL pipelines, and production tooling — including infrastructure that cut document retrieval time by 80% and deadlock resolution time by 90%. I work primarily in Python, with FastAPI, LangGraph, LangChain, Qdrant, Airflow, and Kubernetes — always happy to talk applied LLM systems, RAG architecture, or agentic evaluation.
