Take ownership of complex frontend features and architectural decisions, driving them from concept to production-ready code.

Collaborate with architects and product teams to define frontend strategies, leveraging modern practices and AI-assisted development tools.

Monitor frontend performance metrics, troubleshoot UI bottlenecks, and work with QA to ensure applications remain rock-solid during busy betting windows.

Champion agile methodologies, delivering incremental improvements and ensuring smooth, high-quality deployments.

Maintain and elevate the quality of the React codebase by refactoring complex components, managing state efficiently, and addressing technical debt.
