Joseph Doyle-Samadi · Software Engineer
I'm Joseph Doyle-Samadi, a London-based software engineer. I build full-stack web applications with React, TypeScript, Python and FastAPI, from SaaS products to reliable backend APIs.
Software Engineering Projects
Full-stack web applications, backend systems and native macOS tools. Explore the live demos, source code and engineering case studies.
Full-Stack SaaS
An app for UK tradespeople that plans rounds, quotes and jobs, then sends bills customers can pay by card, Apple Pay or Google Pay. It keeps working with no signal on the round.
Full-Stack Platform
A multiplayer poker platform with a Python game engine, Redis-backed rooms, human and AI players, and a polling-first browser client.
Full-Stack SaaS
A web app that searches official Google Places data for local businesses with no website listed, then delivers private, map-based lead results with CSV export and flexible Stripe pricing.
Native macOS App
A native Mac app for Codex and Claude Code. Discover and manage skills and plugins, track usage limits, and keep your Mac awake while monitored tasks run.
Passion led me here

React, Next.js and TypeScript applications with Supabase authentication, Stripe payments and Cloudflare Workers.
Python, FastAPI, Node.js, Express, PostgreSQL and Redis, with a focus on authentication, state management and modular architecture.
Responsive HTML, CSS, JavaScript and React interfaces, plus interactive Three.js scenes and native macOS tools with SwiftUI and AppKit.
