WHAT I'M WORKING ON NOW

RESEARCH

MZI-UNITARY Electrically tuned MZI-mesh photonic unitary for the QCAP GBS platform — programmable interferometric network under FPGA-based control. IN PROGRESS

GBS-SLE Systems-level engineering for the NSF NQVL QCAP project — control, timing, and readout for a Gaussian boson sampling architecture on integrated photonics. IN PROGRESS

QD-SIM Simulator predicting single-photon purity and brightness of quantum-dot emitters versus temperature, and inverting a purity target into per-component requirements. IN PROGRESS

SNSPD-ANTILATCH Began as a reproduction of Djamen Tchapda et al., Proc. SPIE 12415 (2023); now an LTspice study of feedback biasing in NbTiN SNSPDs. A feedback-bias scheme, unlike passive shunts, widens the latch-free load range (63 to 97 Ω at 27 nH) with ~25% faster recovery, with a controller-latency limit of ≤50 ps at 27 nH. IN PROGRESS

PORTFOLIO This site — Orion star-map shell over static, machine-readable content. ACTIVE

ORION-ASSISTANT Local-first AI assistant — voice, gesture recognition, persistent memory, all offline. ACTIVE

HERMES Point-to-point file transfer between one person's devices, staged through a token-gated Raspberry Pi relay or sent directly over pinned mutual TLS. IN PROGRESS

GABRIEL A group chat for one person's devices and agents, end-to-end encrypted over Firestore with FCM push. DONE

HERCULES Personal strength-training tracker: React Native/Expo and Firestore, an XP and rank engine in TypeScript and Python, and a Dash desktop dashboard. DONE

This is a now page — a quarterly snapshot of current work. If the LAST SYNC date is more than a quarter old, ping me about it.
