Building tools where libraries, security, and purpose overlap.
I'm Paul Clark — Application Systems Analyst, MLIS, and AI-augmented developer with 30 years building production systems for public service. I help libraries and government agencies ship secure, practical software that the people depending on it can trust.
What I build
I bring together 30 years of library domain knowledge, production-grade engineering, and AI-augmented development to ship systems your team can depend on.
Library Systems Integration
ILS integrations, access control workflows, patron registration pipelines, and secure data handling. Built for LCPL in production — I know what breaks and what holds.
AI-Augmented Development
Using Claude and structured prompt engineering to ship at 3–5× the pace of traditional development. Architecture and security judgment stay human. Tedious execution gets automated.
Security Engineering
Applied cryptography, AES-256-GCM, post-quantum primitives, threat modeling, and fail-closed design for public-sector and compliance-sensitive environments.
API & Workflow Automation
LibCal, SirsiDynix Symphony, C•CURE 9000, ArcGIS, and custom webhook architectures. I specialize in connecting systems that weren't designed to talk to each other.
Data Analysis & Reporting
Library analytics, IMLS data pipelines, operational dashboards, and public-sector visualization. Google Data Analytics certified. I turn library data into things decision-makers can act on.
Systems Analysis & Advisory
Integration architecture, vendor evaluation, and technology strategy for public libraries and county IT. I've been on the inside — I understand how these decisions actually get made.
Production systems & public projects
A mix of internal production systems built for LCPL and public portfolio work demonstrating applied cryptography, browser security, and library technology.
Secure Patron Registration Platform
ASP.NET Core MVC platform handling online library card registration with encrypted document upload, ArcGIS address validation, ClamAV malware scanning, and automated patron creation via SirsiDynix Symphony Web Services. 8-layer security pipeline. Deployed in production.
SwipeWatcher — Access Control Monitor
Real-time C•CURE 9000 door event monitor via Victor Web Services / SignalR. HMAC-signed webhook pipeline, Pushover and email alerting, OpenTelemetry tracing, Prometheus metrics, Kubernetes/Helm deployment. Zero missed events in production.
LibCal → C•CURE 9000 Integration
Event-driven integration that automatically provisions door access clearances from LibCal meeting room reservations. Patrons unlock rooms with their library cards — no manual staff steps. Recognized with the I² Innovator/Inspirator Award.
Crypto Lab — 99 Live Browser Demos
Browser-based cryptography suite spanning 2,500 years of history to NIST FIPS 2024 post-quantum standards. No backends, no accounts. Covers symmetric, asymmetric, ZK proofs, homomorphic encryption, threshold signatures, and historical ciphers.
30 years building systems that serve people
I'm an Application Systems Analyst at Leon County Public Library in Tallahassee, FL, where I've spent three decades turning operational complexity into systems that library staff and patrons can actually depend on.
My work sits at the intersection of library domain expertise, production engineering, and applied security — a combination that's genuinely rare. I understand both the technical architecture and the human workflows that depend on it.
I use AI as a true development partner — Claude and GitHub Copilot let me ship at a pace that wasn't possible before, while keeping architecture decisions and security judgment firmly human. The 74 public repos and 48 live demos are the proof of concept.
Everything I build is anchored by the belief that technology is a gift meant to serve people well — and that the standard for "good enough" is whether the person depending on it can trust it.
Let's build something worth building.
If you're a library, county IT department, or public-sector organization with a systems problem — or a developer looking to collaborate on something meaningful — I'd love to hear from you.
