Callum Deas

Front-end & mobile engineer at FanDuel · Scotland

I'm a front-end and mobile engineer at FanDuel, working on Sportsbook with React, React Native and TypeScript. Outside of that I build my own products and sites for clients in the bridal beauty world, with a focus on clean interfaces, real-time systems and AI integrations.

This is the text version. for the full experience (needs WebGL).

▸ THE CHAPEL

Knotless

Knotless is the platform I am building for wedding and event professionals: one place to manage enquiries, bookings, proposals and clients, with an AI assistant that actually knows your business.

  • Drag-and-drop block editor for proposals and emails
  • Client-facing proposals with analytics and status tracking
  • Claude-powered assistant with database query tools
  • Gmail API + Resend sending with automatic fallback
  • Real-time updates across the app via Supabase

Built with Next.js, TypeScript, Supabase, PostgreSQL, Claude API, Resend

▸ THE WORKSHOP

Macbelt

Native macOS app · Released

Macbelt is my personal tool belt for the Mac. It replaced two paid apps I used every day: clipboard history, screenshots, annotation, OCR and screen recording, all native, with no servers and no telemetry.

  • Unlimited clipboard history with full-text search in SQLite
  • Pinboards, paste stacks and quick-paste shortcuts
  • All-in-one capture: select, annotate, OCR, pin or record
  • Ignores password managers; your clipboard never leaves your Mac

Built with Swift, SwiftUI, AppKit, SQLite

▸ THE ARCADE

Name Game

Multiplayer party game · Live on web and iOS

Teams take turns describing names pulled from a shared bucket while their teammates race the clock. Play across phones in real time, or pass a single phone around the room.

  • Authoritative real-time game server
  • Web and native clients sharing one pure game-logic package
  • AI-generated name packs with content moderation
  • Pass-and-play mode for one device

Built with Next.js, React Native, Expo, PartyKit, TypeScript, Turborepo

▸ THE FARMHOUSE

Dish

Mobile app · Live on iOS

Dish is where my recipes live. Import one from anywhere or write it up, plan the week, and get a shopping list sorted by aisle. Share a kitchen with the people you cook with, and it all works offline.

  • AI recipe parsing from links, text and photos
  • Weekly meal planning with generated shopping lists
  • Offline-first sync between household members
  • Bundled grocery classifier to sort lists by aisle

Built with Expo, React Native, Fastify, PostgreSQL, Drizzle, PowerSync

▸ THE HILL

Gloaming

iOS app · coming soon · In development

Gloaming turns how you feel into a walk. Each day you take one step, onto ground as high as you felt, and over the months your own hill takes shape. Its colours come from a real Scottish dusk, the gloaming.

  • Home screen is a hand-built contour map of your year
  • Quick check-ins with feeling words, notes and intentions
  • Home Screen, Lock Screen and Control Center widgets
  • Optional Apple Health State of Mind and iCloud sync; private by design

Built with Swift, SwiftUI, SwiftData, WidgetKit, HealthKit, CloudKit

Freelance · Live

Alongside my day job I build sites for small businesses. Each shop on this street is a real client, all from the bridal beauty world: polished, fast sites that win bookings.
