- Advanced expertise in Lua, including metatables, coroutines, closures, runtime optimization, and memory management.

- Strong understanding of Solar2D's rendering pipeline, scene lifecycle, event dispatch system, physics engine, and asset management.

- Demonstrated ownership of complete mobile game architecture, including deployment, monetization, optimization, and live updates.

Core Responsibilities :

- Architect scalable game systems using Solar2D and Lua.

- Develop reusable gameplay frameworks, entity systems, UI architecture, and animation pipelines.

- Optimize rendering performance to consistently maintain 60 FPS across low-end Android devices and modern iOS devices.

- Profile and eliminate CPU bottlenecks, memory leaks, excessive draw calls, and Lua garbage collection spikes.

- Implement advanced game systems including state machines, object pooling, scene management, asset streaming, save systems, and localization.

- Integrate native plugins using Solar2D Native when framework limitations require platform-specific functionality.

- Implement mobile monetization using AdMob, AppLovin MAX, Unity Ads, IronSource, In-App Purchases, and subscription models.
