Past Work
I’ve built systems across a wide range of domains. These projects were delivered for clients and are described generically. If a capability below matches what you need, I can apply that same depth to your project.
🧠 AI & LLM Systems
RAG Pipeline with Verification
Built a retrieval-augmented generation system that grounds LLM responses in verified source documents using vector search and graph traversal. Designed for environments where hallucination is not acceptable.
Chat over Export Data
Built a chatbot that answers questions over a ChatGPT export archive using RAG. Ingests conversation history, indexes by semantic content, and surfaces relevant context for each query.
Medical Literature Pipeline
End-to-end NLP pipeline: scrapes PubMed and EuropePMC, streams 3M+ abstracts through spaCy for linguistic analysis, stores in SQLite with FTS5, and generates LaTeX-formatted statistical reports.
Custom AI Agent
Contributed to and deployed a production AI agent platform with tool-calling, session management, plugin system, and multi-platform gateway (Telegram, Discord, Slack, CLI, TUI).
🕸️ Data Extraction & Scraping
Email-to-Data Pipeline
Automated system that receives emails via webhook, parses structured content, and routes data into a database and notification system. Handles attachments, formatting, and error recovery.
Multi-Source Web Scraping
Built scrapers for government portals, e-commerce catalogs, scientific databases, and archival document repositories. Includes proxy rotation, bot-detection evasion, and structured output to databases.
Financial Data Pipeline
Backtesting system in Perl consuming historical asset price data from file imports and live API feeds. Designed for quantitative analysis of trading strategies.
Newsletter Automation
Daily automated newsletter generator that scans research feeds (arXiv, RSS), curates content by relevance, summarizes via LLM, and distributes via email.
📡 Signal Processing & Computer Vision
Spread-Spectrum Signal Decoding
Decodes DSSS CDMA signals from MP4 video files and webcam feeds. Implements chip-rate demodulation at 10Hz from raw pixel data. Built in Rust for real-time performance.
3D Scan to CAD Pipeline
Converts real-world objects from point clouds and photogrammetry into structured CSG (Constructive Solid Geometry) representations for CAD software and 3D printing.
Object Tracking from Video
Custom computer vision tracking system that records position and orientation of objects from video feeds. Built for scientific measurement in environments where off-the-shelf trackers fail.
🌐 Web & App Development
Full-Stack Sites
Built production websites for organizations including a guild community site, a Socratic school, and a music venue. Tech varies by need — static, serverless, or full backend.
Grading Assistance Pipeline
Browser-based tool for a virtual school: downloads student submissions from a web portal, extracts text from PDFs and Word docs, processes via LLM, and pastes graded results back into the web interface.
Market-Making Bot
Automated trading bot for the Tipjar platform. Executes market-making strategies with configurable spreads, order sizing, and risk controls.
Slack & Social Bots
Built and deployed multiple bots for Slack and other platforms — notification systems, moderation helpers, and automated responders.
⚙️ Infrastructure & DevOps
Machine Configuration & Backups
Reproducible system configurations using NixOS, automated encrypted backups via restic to cloud storage, and secrets management with sops. Edge-case recovery tested regularly.
Secure Agent Proxy
Built a local proxy that allows cloud-hosted AI agents to access local network resources through an authenticated tunnel. Includes request filtering, rate limiting, and audit logging.
Voice Bridge
Voice-enabled interface for an AI agent, allowing natural language interaction through speech recognition and text-to-speech. Designed for hands-free operation in lab and workshop environments.
Serverless Deployment
Deployed production serverless applications on Cloudflare Pages and Workers with CI/CD pipelines, environment secrets management, and custom domain routing.
🔗 Blockchain & Cryptographic Provenance
Forensic Audit CLI
Command-line tool that produces cryptographic provenance records for autonomous agent actions. Every decision is signed, timestamped, and independently verifiable — designed for compliance and governance.
Video Provenance Protocol
Zero-knowledge protocol that proves a video has not been tampered with between capture and viewing. Uses anonymous multi-witness consensus to verify integrity without revealing the full video.
Webhook with Verification
Parser and decision engine for alert notifications via webhook. Validates authenticity of incoming payloads, routes by content rules, and logs decisions immutably.
This is the depth of experience I bring to every project, large or small.
