HTML5 Game & iGaming Development

I help game studios and product teams build and maintain browser games for desktop and mobile, from playable prototypes to features in existing production games.

Tell me about your project

My experience includes production casino games for international iGaming brands and platform partners, as well as HTML5 browser games across multiple genres. I work on gameplay systems, game features, engine improvements and the connection between game state and presentation.

I use TypeScript and JavaScript with PixiJS, CreateJS and Phaser, depending on the existing engine and project requirements. Work can include integrating Spine animations, images and audio, adapting layouts for different devices or investigating performance issues in a game already in development.

If you need help with an existing game, share the engine, the feature or bug and the expected behavior. For a new game or prototype, a short concept and target devices are a useful starting point. We can agree a focused delivery or discuss an ongoing engineering role within your team.

How I can help

  • HTML5 browser games and playable prototypes
  • Gameplay features and game systems
  • Spine animation, image and audio integration
  • Responsive layouts, asset and engine optimization

Working together

  1. We review the game brief, engine and expected behavior.
  2. I implement the agreed systems within the existing architecture.
  3. We review gameplay, presentation and behavior on the target devices.
