| 🛰️ | Killswitch — SDTH | Software-Defined Directed Energy Counter-UAS node — a portable targeting brain (detect → track → predict → aim → human gate) running today on a webcam, an ESP32 and a ~$200 gimbal, designed to re-host onto a military beam director without a rewrite. Firmware-enforced safety (deadman timer, burn ceiling, checksummed arming). Team project (Killswitch, SDTH 2026); I own the detection / tracking / prediction stack | Python, YOLOv11, ByteTrack, Kalman, ESP32/C++, MQTT | 🏆 Hackathon → 🚀 exploring startup - ✅ Live |

Coursework and academic builds from the MSc in Enterprise AI — team size and my role stated for each.
| Project | Description | Stack | Role | |
|---|---|---|---|---|
| 📑 | MediExtract | Grounded clinical-note extraction — pulls medication / dose / frequency / allergy from dictated notes, with a verbatim-evidence gate that blanks any field it cannot quote back to the source, and deterministic abstention instead of LLM guessing | Python, Gemini 2.5 Flash, OpenRouter | Individual (PE6202) |
| 🗾 | Japan Itinerary Planner | Generative + agentic trip planner whose pass-vs-tickets verdict is computed by a deterministic calculator (never guessed by the LLM), with every factual claim carrying a dated citation | Gemini, Node/FastAPI, rule-based RAG | Team of 6 (PE6203) — Module 1/2 prompts + calculator logic |
| ⚕️ | Insurance Claim Agent | Hand-rolled ReAct agent for health-insurance claim first response — approve / request-document / escalate — with in-code guardrails, a gated append-only decision ledger, and a live multi-model evaluation battery | Python (standard library only) | Team of 6 (PE6201) — loop, tools, guardrails |
