Computer engineering student at High Point University. I build agentic systems — mostly tools that check other systems' work, and platforms people actually pay for.

Work

Groundskeeper

PR-review agent · Prebid.org · Python

Compiles a repository's own documented conventions into an enforceable ruleset and judges pull-request diffs against it. Deterministic, keyless checks catch CI tampering; an LLM judge handles the semantic rules, and never sees the PR title or description, so the author's framing can't bias the verdict. Benchmarked at ~85% precision / ~39% recall against human reviewers on held-out prebid/salesagent PRs — where the two general-purpose review bots already running covered none of the human-flagged issues.

adcp-buyer-agent

Protocol buyer + fuzzer · Python

A Claude-driven buyer that runs a campaign end to end against a live AdCP sales agent: product discovery, budget planning behind a spend gate, media-buy creation — across hand-rolled MCP, A2A and REST transports. A deterministic core does the wire work, the model does the judgment, and the money commit sits behind a durable executor the LLM never touches. A companion protocol fuzzer is designed and not yet built.

salesagent-review-bot

Multi-agent PR reviewer · Prebid.org

Merges two colleagues' review tools into one pipeline — Chris Huie's review charter, detectors and pattern catalog as the rigor, Konstantin Mirin's scout → review → draft-only-post flow as the chassis. Sixteen review agents unioned into eleven canonical dimensions behind a single synthesis and readiness gate, with their licenses and provenance tracked throughout.

Prebid Marketing Kit

Claude Code plugin · Prebid.org

Built after Prebid's marketing team — then paying an outside agency ~$10K/month for WordPress edits — asked for an in-house alternative. Lets non-technical staff run website and mailing-list workflows in plain English, with a human approving anything that goes public. I wrote the onboarding guide and trained the team; it's now used by Prebid's entire marketing and engineering teams.

R6 Insights

Analytics & coaching SaaS · founder · 2025–present

A commercial platform for professional Rainbow Six Siege teams, used by roughly half of Tier-1 rosters: a binary .rec replay parser, a PyTorch computer-vision VOD analyzer, AI-generated coaching reports, multi-tenant Firebase, a Discord scrim bot, Stripe billing, and a desktop client. I run the engineering and the customer support.
