I'm Paul Harrison.
I build software. Lately, it talks back.

Computer Science @ Michigan | AI + SWE + Security

I design and ship full-stack products across modern web stacks and cloud infrastructure. My recent work spans voice agents, LLM pipelines, Vue + TypeScript frontends, FastAPI services, and agentic systems, built with a focus on reliability, performance, and strong engineering fundamentals.

About Me

Get to know me

I'm Paul Harrison, a Software Engineering-focused Computer Science student at the University of Michigan. I enjoy building production-minded systems where clean architecture, strong UX, and measurable impact all matter.

From backend APIs and data workflows to frontend product experiences, I like owning features end-to-end. I care about pragmatic engineering: writing maintainable code, validating with real users, and continuously improving performance and reliability.

Technical Experience Internship experience building and shipping AI-driven software in startup and product environments.

Lazio Partners · AI Software Engineer Intern

Ann Arbor, MI | June 2026 - Present

Primary engineer on an AI-driven go-to-market platform at an early-stage startup. Built an LLM lead-generation pipeline over a graph of ~20,000 companies and ~150,000 contacts, turning raw sources into scored, QA-checked, client-ready leads (Python, FastAPI, Prefect, ArangoDB). Also shipped the company's flagship AI content engine that drafts, critiques, and auto-publishes posts to LinkedIn.

Whomlab · Full-Stack Software Engineer Intern

Prague, Czech Republic | Jan 2026 - May 2026

Built a voice-driven survey platform projected to serve 7,500+ users across five EU-financed programs. Engineered a LiveKit WebRTC pipeline (browser mic → LiveKit Cloud SFU → Python livekit-agents worker with Whisper STT → Venice AI LLM → OpenAI TTS). Shipped Vue 3 + TypeScript frontend with a custom useLiveKit composable, MediaRecorder capture, data-channel dispatch, and Pinia state, backed by FastAPI + Firebase Auth, Firestore, and Cloud Storage.

Charlemagne Labs · AI & Security Software Engineering Intern

Ann Arbor, MI | Aug 2025 - Dec 2025

Fine-tuned Gemma 3 (270M) with LoRA adapters for phishing URL classification, merging weights with a custom classifier head for dependency-free inference in a FastAPI serving layer. Built a multi-backend evaluation harness (Hugging Face, Ollama, LiteLLM for GPT/Gemini) benchmarking accuracy, precision/recall, and latency across realistic phishing and social-engineering scenarios. Engineered URL, DOM, and headless-browser feature extractors: domain signals, password-field and urgency-language detection, image hashing for look-alike site detection.

SupermaxCloud · Cybersecurity & Infrastructure Engineering Intern

Chicago, IL | May 2025 - Aug 2025

Automated vulnerability scanning across internal and internet-facing systems with Nmap and Shodan, cutting manual review time by 70%. Managed infrastructure security via firewall rules, access controls, and Wazuh-based monitoring. Built Zabbix and Kuma dashboards and health checks, improving visibility into uptime and service issues across the fleet.

Projects Selected software projects with a focus on full-stack engineering, data systems, and production deployment.

Whaleden Comic Artist Discovery System

An agentic data pipeline that discovers and ranks 1,400+ comic artists across Bluesky, Reddit, and Dribbble. Features a 4-stage Ollama (Llama 3.1 8B) LLM pipeline with schema-constrained JSON outputs and confidence thresholds, alongside a Streamlit browsing UI, resilient scraping, deduplication, and normalized Postgres storage.

Simon Smiles

Real-time facial expression game powered by Flask, OpenCV, and FER inference, with a responsive browser UI and webcam integration. Deployed to Google Cloud Run with production HTTPS and CORS configuration.
