        Both documents below were produced for a client engagement under non-disclosure agreement (NDA). They are described
        accurately here and are <strong>available on request</strong>; a public version would need
        a redaction pass and sponsor sign-off first.

        <h3>Knights Counsel: Technical White Paper, v1.0</h3>
        <p class="writing-role">Co-author · sole author, system design and behavior specification sections · August 2026</p>
        <p>
          A full technical account of the system's architecture, behavior specification, evaluation
          methodology, and results, prepared for enterprise information technology (IT) and the client. The sections I wrote
          cover the two-agent orchestration topology, the thirteen numbered behavioral
          requirements, the grounding and citation enforcement model, and the configuration
          baseline treated as version-controlled.
        </p>

        <h3>Knights Counsel: Final Design Document, v2</h3>
        <p class="writing-role">Contributing author · sole author, system design section · 2026</p>
        <p>
          Requirements, architecture, and design rationale for the sponsored capstone. Includes the
          behavior test set and the architecture decision record covering the six-agent to
          two-agent reversal, written up as a record rather than deleted, so the reasoning survives
          for whoever picks the project up next.

        <h3>Architecture decision records</h3>
        <p class="writing-role">Author · ongoing through the engagement</p>
        <p>
          A running set covering platform selection, delivery surface, access model, session
          memory, citation rendering, prompt-language requirements, naming enforcement, and
          fallback strategy. Each captures context, decision, consequences, and status, including
          the records that document reversals of the team's own earlier decisions.

        <h3>Hardening Build Systems</h3>
        <p class="writing-role">Undergraduate research assistant · University of Central Florida · Oct 2025 – May 2026</p>
        <p>
          Empirical research on the security and reliability of open-source software build systems.
          I diagnosed build failures by hand across six build systems, and built the tooling that
          converts raw experimental output into LaTeX-ready tables and pgfplots figures used in
          project reporting. The failure categories that came out of that work are what the
          <a href="project-build-recipe.html">build-inference study</a> is now built to measure.

        <h3>Human Factors Group Study</h3>
        <p class="writing-role">Research assistant · University of Central Florida · Feb 2025 – May 2026</p>
        <p>
          A study of how programmers debug code collaboratively in groups. I ran experimental
          sessions and instrumented participants with biometric equipment measuring heart rate,
          respiration, skin conductance, gaze, and prefrontal cortex blood oxygenation. Worked
          under human-subjects research protocol with the associated ethics training completed.
        </p>
      </div>
    </section>

    <section aria-labelledby="h-interests">
      <h2 id="h-interests">Research interests</h2>
      <p>
        Applied artificial intelligence (AI) systems and the evaluation methods that validate them: large language model (LLM) agent design,
        retrieval grounding and citation enforcement, guardrail and refusal behavior, and the
        measurement problem of separating genuine capability from fit to a chosen benchmark.
      </p>
      <p>
        Secondary interests in empirical software engineering, particularly build-system
        reliability and reproducibility, and in human-computer interaction at the level of
        accessible, well-structured interfaces.
