Hybrid retrieval + Cohere Embed/Rerank cross-encoder + an LLM contradiction judge, built eval-first: a planted-contradiction harness (precision/recall, MRR/NDCG, calibration) gates the build in CI. A real-model run lifted contradiction F1 from 0.50 (baseline) to 1.00 at a 0% false-positive rate.

Extracts the transferable idea from candidate AI techniques and scores it against a system's real open problems; ships a decoy-injection eval that fails CI if hype leaks into the digest (1.0 decoy-catch / 0.82 recall over 27 candidates). Also packaged as an installable agent skill.

A three-machine Tailscale GPU mesh with a tiered local-LLM router — smallest model that can answer, escalating only when needed — running the inference and overnight automation behind the projects above.

Built a web-based product-sales dashboard for the Storylines mobile game in Vue 3 + Firebase SDK.

Owned Firebase liveops for the Storylines mobile game; integrated with a Unity client.

Two tracks across the agency's e-commerce practice:

• —Senior Solutions Engineer — a 3-person “special ops” team that owned the hardest cross-project problems: built scalable shared tooling and troubleshot critical issues across the client base.

Delivered campaign technology at one of Canada's largest agencies — matched the right tools to each project and guided the front-end team.
