Flutter / Dart

An offline, ad-free card game of Classic Hareeg: one human against three CPUs across a four-tier difficulty ladder that genuinely knows the game. The rules live in one pure-Dart engine nothing can reach around. Built fast with AI agents and kept correct with the guardrails around them: unit, integration and regression tests, an invariant sweep that drives full matches, golden replays, and automated review in CI. Around 87,000 lines across the app and its tests; one codebase ships to Android, web and desktop.

Next.js / React Query / Zustand / GraphQL / Vercel / TypeScript / Tailwind CSS

A GitHub network auditor that runs with no server to maintain and no database I pay for. Each user signs in with their own GitHub OAuth quota and the browser does the long-running work, so it handles networks in the tens of thousands: adaptive refresh windows, retries with exponential backoff, and a private Gist standing in for the database. It even classifies deleted accounts by reading the GraphQL and REST APIs against each other, spending no extra quota.

Svelte / Express.js / Vite / TypeScript / Tailwind CSS

A chess platform where both the AI and multiplayer modes extend one tested rulebook. The Stockfish engine runs in a Web Worker over the UCI protocol so the board never freezes, and a single difficulty setting fans out into six engine parameters so easy games feel human rather than just weak. Multiplayer runs on a small Node and ws server with session-based reconnection and clocks that survive a dropped connection.
