Experience
01
PatePlay
Software Developer
Developed backend systems and frontend game features for iGaming and land-based casino platforms using TypeScript and PixiJS, collaborating with designers and artists to deliver performant, production-ready gaming experiences.
- Optimized gameplay performance by identifying rendering and logic bottlenecks, resulting in smoother animations, lower resource usage, and a more responsive player experience across multiple game configurations.
- Improved the maintainability and scalability of the codebase by refactoring existing systems into reusable, modular components, simplifying future feature development and reducing technical debt.
- Bridged the gap between design and implementation by resolving technical constraints related to visual assets, animation behavior, and game logic, ensuring consistent functionality and a polished user experience across both iGaming and land-based casino platforms.
