    EvalWard LLM regression gate for CI/CD

    Aug 2026

    Personal Project

    A CI gate that catches silent quality regressions in LLM-powered features. It re-runs a bank complaint-triage prompt against a 150-case golden dataset built from the public CFPB Consumer Complaint Database, diffs macro-F1 against the last promoted baseline, and blocks the merge when quality drops materially — naming the exact cases that flipped.

    Agentic AI Coursework

    A local-first AI tutoring agent that calls external tools over the Model Context Protocol. Two MCP servers in C# (stdio and streamable HTTP transports) feed their tool catalogs to an LLM agent via the Microsoft Agent Framework, with a streaming Blazor chat UI orchestrated by .NET Aspire.
