Hi, I'm Matt.

Built, shipped, still running
Products I've designed, built, and operated end to end under OneNomad LLC. Consumer apps, vertical SaaS, and the AI infrastructure underneath, live on the web and in both app stores.
FieldLedgr
Mobile-first quote-to-cash platform for trades businesses. Estimates, e-signatures, invoicing, payments, and automated follow-ups in one place, built on Payload CMS, Stripe Connect, and Cloudflare Workers.
SnapTab
Bill-splitting app that scans receipts with AI and generates QR-coded payment requests for Venmo, Cash App, and PayPal. React Native + Expo, shipped to both the App Store and Play Store.
Dungeon Diary
AI-powered campaign management for Dungeon Masters: world building, NPC generation, session tracking, encounter management, and AI portraits, organized around your active campaign.
Game Night
Two-sided marketplace for tabletop gaming events. Venues get ticketing, scanning, and payments; players get map-based discovery of local game nights filtered by type, price, and distance.
Thyme to Plan
Meal-planning and nutrition app bridging recipes, pantry, and a 3M-food database. Web and native mobile share one Payload backend, so a meal logged on the phone updates the weekly plan and macros instantly.
przm Memory
Long-term memory for AI agents: hybrid retrieval across vectors, BM25, and a typed knowledge graph, with episodic, semantic, and procedural layers that survive context-window compaction. Scores 92% R@10 on the LoCoMo benchmark.
przm Voice
An evolving personality layer for AI agents. Emotion tagging, Big Five trait modeling, and behavioral signals keep an assistant's voice coherent and growing with you instead of resetting every session.
Cortex
Permission-aware company knowledge for AI agents. Ingests Slack, Confluence, Notion, Jira, GitHub, Gmail, and Drive into one MCP-native retrieval surface, with ACLs enforced at the database layer and on-prem deployment.
The short version
I've spent the last 15 years shipping software. Right now I'm the Technical Engagement Lead at Elevate Digital; before that came General Motors' motorsports analytics group, Synchrony, Earnest, Banjo Health, and Red Ventures. I've led teams, architected systems from scratch, and written more React than I'd like to admit.
In 2026 I founded OneNomad LLC as the home for my own products: consumer apps, vertical SaaS, and AI infrastructure, all listed above. Running real software with real users keeps me honest about what ships cleanly and what falls over in production.
I care about craft, accessibility, and tools that actually solve problems. Most of my work is end-to-end: design, frontend, backend, infrastructure, and the business decisions that hold them together.
TypeScript end to end, with a bias toward boring, reliable infrastructure and interfaces that hold up under real use.
