I’m Mary, a Full Stack & Game Developer helping startups, businesses, and creators build, fix, and launch digital products. I specialize in Unity games, online games, arcade games, multiplayer games, VR games, HTML5, JavaScript, Phaser.js, WebGL, Three.js, React Native, Flutter, iOS and Android mobile apps. I build game systems, multiplayer features, mobile apps, APIs, backend systems, Firebase and Supabase integrations, UI, authentication, payments, and cross-platform experiences from idea to production.
FAQ
Can you build an HTML5 game inside my existing website?
Yes, I can scope an embed or integration for your hosting and layout. Send the website and one reference mechanic.
Can you fix Phaser touch controls on mobile browsers?
I can reproduce the input and layout issue on agreed devices. Share the build and the exact failed interaction.
Can you add a leaderboard using Node.js or Supabase?
Yes, as a bounded score endpoint and leaderboard. Score validation and any anti-cheat rules must be defined before implementation.
Can you stop game progress disappearing after refresh?
I can inspect save-state and identity handling. Local-only progress and account-synced progress are different scopes.
Do you create quiz and educational arcade games?
Yes, for a clear mechanic, content set and target browser. Send the learning goal and supplied question/art assets.
Does the $650 package include multiplayer matchmaking?
No. Realtime rooms, authoritative servers and matchmaking require a separate estimate after the game rules are defined.
Can you build MediaPipe or TensorFlow.js gesture controls?
I can assess a webcam-control prototype as a separate scope. Camera support, tracking accuracy and a keyboard/touch fallback need testing.
Can you make a Reddit Devvit game?
Send the community use case for feasibility and platform review. It is an adjacent experiment, not included in the standard website-game package.
Will you provide artwork and music?
Packages use client-supplied licensed assets or agreed placeholders. Original artwork and music need separate scope and rights.
What should I send before ordering?
Reference game, core mechanic, target devices, existing code and assets. A short playable brief gets you a more accurate quote.
