// SELECTED WORK
Things I've built.
A cross-section across all three levers — from voice agents and content pipelines to compressible-flow solvers and real-time computer vision. The range is the point.
AI Automation · Voice
HVAC Lead Voice Agent
A new Thumbtack lead triggers an automated outbound call within seconds — qualifying the job and booking it before a competitor picks up the phone. n8n, ElevenLabs, Twilio.
AI Automation · Content
End-to-End Video Pipeline
Raw footage to published video and shorts, untouched by hand: Groq transcription → Claude editing plan → FFmpeg cut → YouTube upload. A whole content workflow as one program.
AI Automation · RAG
Custom Knowledge Base
A searchable, source-grounded knowledge base over hundreds of hours of video — with conflict flagging and an MCP server so assistants can query it directly. Supabase pgvector, OpenAI embeddings.
Engineering · CFD
RailPulse Tunnel Simulator
A 1D compressible-flow solver for pressure transients as trains enter tunnels — MUSCL-Hancock reconstruction with an HLLC Riemann solver, validated against the ThermoTun reference. Python.
Engineering · Computer Vision
Red-Light Violation Detection
Real-time detection and tracking that reads signal state and flags red-light runners from a live feed — YOLOv11 + ByteTrack, tuned for edge hardware. Python, OpenCV.
Engineering · Thermodynamics
CALPHAD Phase-Diagram UQ
A reassessment of the Cu–Ga thermodynamic system with a Bayesian MCMC pipeline for uncertainty quantification — turning a phase diagram into a model with error bars. pycalphad, ESPEI.
Custom Build · Web
Compliant Dispensary Site
A full WordPress storefront with age-gate, live menu integration, and California DCC compliance baked in — shipped on Docker. Marketing site meets regulated retail.
Custom Build · Business Ops
Solar CRM & Back Office
A multi-domain operations system for a solar business — bookkeeping, payroll draws, CRM, and KPI tracking unified into one assistant-driven workflow. Google Apps Script.
Custom Build · iOS
EchoMark Audiobook Reader
A native iOS reader with real-time text-to-speech and a voice-capture highlight system, built on the Readium toolkit. Swift.
Yours could be next.
If your problem looks nothing like these, that's fine — the through-line is hard problems, not a fixed menu.
