Projects

Solo Founder & Full-Stack Developer

A conversational AI agent that turns kilometer-scale fiber-optic (DAS) sensing data into plain-language bridge-health answers — a verdict, the reasoning, and an exportable engineering report, in one question. Solo-built end-to-end, trilingual (Chinese/English/French) from day one.

• Compresses the full workflow — raw DAS waveform → spectral analysis → modal frequency estimation → health verdict — into a single conversational exchange, computed in seconds to under two minutes
• Produces standard engineering output: PSD spectra, modal frequencies, strain RMS, five-level color-coded alerts, and a one-click archivable Word report
• Built solo end-to-end: frontend, backend, AI agent design, and the underlying DAS signal-processing domain logic
• Trilingual product (中/英/法), switchable in one click — the same i18n design principle later applied to this personal site

AI Assistant Lead, Team of 4 — DFW 2026 AI & Startup Competition (Finalist)

A 4-person team competition entry for the DFW 2026 AI & Startup Competition, now a finalist. The team's existing bridge structural-health monitoring dashboard needed a way to answer plain-language questions about live DAS data — I proposed and led embedding a conversational AI assistant directly into that dashboard as one integrated module.

• Advanced to the finals of the DFW 2026 AI & Startup Competition
• Proposed and led the integration of a conversational AI assistant into the team's pre-existing bridge-monitoring dashboard, rather than building a standalone app
• Distinct in scope from MurSense: here the AI assistant is one embedded window within a larger dashboard product built by a 4-person team, not an independent full-stack product built solo
