AI, ML, and Data Science

AI has been my focus since 2021, when I chose it over robotics for my bachelor's. I am now finishing an MS in AI at Northwestern and enjoy building models, working with data, and discussing the field's real-world questions.

Building a knowledge graph over two mortgage-finance standards, and the agents that answer questions against it without inventing sources.

Context

Mortgage tech runs on two dense standards: MISMO, which defines every datapoint on a loan file, and FIBO, a formal OWL ontology of finance. Ask a language model about either and it answers fluently, and sometimes invents the section numbers it cites.

What I built

I parsed both standards from their native formats, FIBO from OWL with rdflib and the MISMO Logical Data Dictionary from its spreadsheet with openpyxl, into one graph of 24,000 nodes and 52,000 edges, joined by 48 cross-standard links I verified by hand. Retrieval runs in five stages (trie, keyword, fuzzy, FAISS semantic search, then a bge-reranker-v2-m3 rerank) and feeds two ReAct agents: a 13-tool FIBO traversal agent and an 8-tool MISMO containment agent. Every draft answer passes an OWL axiom check and a citation audit before release.

Result

25 of 27 on a structured evaluation set, and zero fabricated citations across every run. On a real ULAD loan-application XML it resolved 56 of 57 elements to graph nodes with no invalid enumeration values. I deployed the pipeline as a 10-tool MCP service for Claude Desktop and GitHub Copilot, with authenticated client access, schema-validated tool inputs, bounded retrieval, request limits, and timeouts to keep agent work within defined resource limits.
