Portfolio
Two decades of building at the intersection of hardware, software, and data — from device drivers shipping on hundreds of millions of devices to cryptographic evidence pipelines for autonomous agents. This is the depth I bring to every project.
⚙️ Systems & Embedded Engineering
Device Drivers & Embedded Systems (Qualcomm)
Developed device drivers, DMA engines, and real-time firmware for mobile platforms shipping at scale. Assembly-level debugging, RTOS integration, inter-processor communication, and hardware bring-up. Wrote code that runs on hundreds of millions of devices.
Real-Time Embedded Systems (Wabtec)
Built and debugged real-time control systems for rail safety equipment. Interrupt-driven firmware, hardware-in-the-loop testing, and safety-critical software under regulatory compliance. Systems where timing is a correctness property.
LabVIEW Device Driver Compatibility Layer (C)
Built a C-language compatibility layer for device drivers that shipped as part of a microscope product. Enabled LabVIEW-based control software to interface with custom hardware peripherals without modifying the existing control stack.
Bluetooth Camera Debug (Embedded)
Diagnosed and resolved bugs in the Bluetooth camera stack for a body camera manufacturer. Involved low-level Bluetooth protocol debugging, camera subsystem integration, and firmware-level issue identification.
🔗 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.
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.
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.
🧠 AI & LLM Systems
RAG Pipeline with Verification
Built a retrieval-augmented generation system that grounds LLM responses in verified source documents using a combination of full-text search, vector search, and graph traversal. Designed for environments where hallucination is not acceptable.
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).
Medical Literature Pipeline
End-to-end NLP pipeline: extracts from PubMed and EuropePMC, streams 3M+ abstracts through spaCy for linguistic analysis, stores in SQLite with FTS5, and generates LaTeX-formatted statistical reports.
Chat over Export Data
Built a chatbot that answers questions over an exported conversation archive using RAG. Ingests conversation history, indexes by semantic content, and surfaces relevant context for each query.
📡 Computer Vision & Signal Processing
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.
Spread-Spectrum Signal Decoding
Decodes DSSS CDMA signals from video files and webcam feeds. Implements chip-rate demodulation, code acquisition, and despreading in Rust for real-time signal extraction.
🕸️ Data Extraction & Automation
Multi-Source Data Extraction
Built extraction pipelines for government portals, scientific databases, e-commerce catalogs, and archival document repositories. Includes anti-detection measures and structured output to databases.
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.
Newsletter Automation
Daily automated newsletter generator that scans research feeds, curates content by relevance, summarizes via LLM, and distributes via email.
⚙️ 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.
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.

R2C Pipeline — Research-to-Commit
Daily automated pipeline scanning arXiv + 6 demand sources (RemoteOK, HN, GH bounties, PyPI). Heatmap matches research to market demand. Full pipeline: scan → match → qualify → report → commit. See the public report →
Hermes Reports — Agent Activity Logs
Self-contained Go server serving agent session reports, dependency graphs, and daily evaluations. Track every Hermes session, visualize agent ecosystem health, and browse historical activity. See the public page →
