RaceDrops
Flagship- The problem
- Drag strips juggle registration, brackets, results, and payments across separate tools, and many tracks have little or no cell signal on race day.
- What we built
- Multi-tenant software for drag strips: a track operator portal, a fan and driver app for iOS and Android, Stripe payments, and offline race-day sync so events keep running without cell signal.
- Stack
- React, TypeScript, Supabase, Stripe, Expo, Vercel
CaliVolt Electrical
- The problem
- A Central Valley electrical contractor needed a site that brings in residential and commercial quote requests and gets them to the team fast.
- What we built
- A full-service website for residential, commercial, and industrial electrical work, with integrated quote and commercial-bid forms, a backend CRM, and Discord messaging integration for new leads.
Pismo Beach Arm Drops
- The problem
- A new sand-drag event at Oceano Dunes needed one home for racers and spectators: event info, brackets, and ticketing that worked with the park's parking QR system.
- What we built
- Event site with brackets, ticketing QR integration, and promo graphics.
West Coast Diesels Dirt Drags
- The problem
- West Coast Diesels added a nine-class dirt drag to their tractor pull and needed brackets, rules, and racer accounts live before a fixed event date.
- What we built
- Production event site with live bracket views, a full rules page, and user accounts. Built on deadline for a live event.
Field Sales CRM
- The problem
- An outside sales rep covering hundreds of accounts across California needed one place to see which accounts are going quiet, log visits, plan routes, and look up vendor ordering details.
- What we built
- A custom CRM with a dashboard that flags dormant and at-risk accounts, voice-memo and business-card activity logging with automatic account matching, tasks, route planning, a searchable vendor directory that checks each new vendor list for changes, and one-click prospect-to-account promotion.
- Stack
- React, TypeScript, Supabase
The Petrie Project
- The problem
- Flinders Petrie's published works survive mostly as scattered scans that are hard to search or read.
- What we built
- A searchable digital archive of Petrie's published works (125 volumes across 4 collections, 1856–1939), transcribed with AI-assisted OCR and full-text search, plus an AI audiobook narration pilot.
This website
- The problem
- A wholesale and events business needed a site that sends leads straight into its CRM, alerts the owner instantly, and shows up in search and AI answers.
- What we built
- Server-rendered site structured for search and AI assistants, with CRM-connected forms and automated text/email alerts.
Currently building: showroom software for a motorsports dealership, connecting existing platforms and inventory.
