Projects
Things I've built — spanning AI tooling, enterprise data, geospatial systems, scientific computing, and self-hosted infrastructure. A few have full write-ups — follow the links.
Stdlib-only guards and a falsifiable intent-record system that let an LLM coding agent run unattended without trusting it to bless its own work — mechanical, testable, and enforced outside the model.

A deterministic tool that reconciles an AI coding agent's natural-language claims — 'the tests pass', 'I created the file' — against what its Claude Code session actually did, calibrated to zero false accusations across 400 real sessions.

A personal project in development: Python orchestration, MCP execution, React, and Rust/Tauri, with permissions separated from prompts and explicit recovery safeguards. Architected and directed with AI-assisted implementation.
A locally running, credentialed Python utility used by colleagues to work with Oracle databases through Claude and Cursor.

A pre-LLM voice-assistant spike assembling the speech-and-vision stack of its day — Google STT, neural punctuation restoration, nltk parsing, pyttsx3 speech, and an OpenCV face pipeline — built before any of it was a single API call.
An interactive touchscreen map for a septic-services business: a customer spreadsheet reverse-geocoded into a filterable Folium map with pricing zones, service-due heatmaps, and upsell alerts — on a repurposed big-screen TV with an infrared touch overlay.

An AI red-teaming experiment: one GPT-4 jailbroken by another to generate novel malware from real samples — a demonstration of model-guardrail failure, never released. Credited at SANS HackFest 2023.
Historical voice-assistant development with wake-word detection, speech recognition, pluggable LLMs, MCP tools, and speech synthesis. Recovery and repair are required before an end-to-end demonstration. Built AI-assisted.
Read the write-up: Jarvis — A Voice Assistant Under Recovery
A fully on-device, FOSS pipeline that fine-tunes a custom text-to-speech voice from a handful of audio samples — decode, loudness-normalize, segment, transcribe, fine-tune, synthesize, evaluate. A separate model-training workflow designed for integration with Jarvis. Built AI-assisted.
Read the write-up: voice-training — A Local TTS Fine-Tuning Pipeline
A personal experiment comparing coding-agent results against frozen acceptance checks, with explicit limits on what a small provider comparison can establish. Built AI-assisted.
An experimental Python router for portable prompt guidance, plus controlled comparisons that retained a negative result. AI-assisted personal development.
A self-managed Debian homelab — GitLab, Vaultwarden, Grafana, Docker behind a reverse proxy — plus a from-scratch web and mail stack for a dozen-plus domains. Most recently, a fleet-wide email-auth remediation that fixed outbound mail silently failing at the major providers.

Packaged scientific-Python tooling behind my NASA and UMBC atmospheric research — crawlers, readers, and regridders that turn raw satellite and observatory data into analysis-ready netCDF.

A Monte Carlo photon-transport simulation for cloud radiative transfer, built as a student and later used to grade peers' implementations as a teaching assistant.
Read the write-up: Monte Carlo Cloud Radiative-Transfer Simulation
A published converter that reads legacy HDF-EOS2 satellite granules and writes CF-annotated netCDF4 with the geographic coordinates reconstructed, so decades-old data opens in current tools.

A one-command file-encryption tool and library on PyPI — password-derived keys, an authenticated cipher, and a versioned file format, carried through the full lifecycle of a published package.

An open-source Adobe Brackets plugin adding syntax highlighting and comment shortcuts for 19 languages the editor didn't support out of the box — from COBOL and Fortran to Julia, R, and Swift — via CodeMirror modes.
