architects, and POs to define short-term priorities and
long-term technical direction. Performed code reviews,
enforced coding guidelines, and maintained
architectural consistency. Developed analytics and
monitoring tools for new features, integrated remote
configs, integration tests, unit tests, and third-party
SDKs. Built tools for designers and artists to streamline

evolution and support. Monitored and reduced
technical debt, maintaining codebase health. Created,
fixed production issues, and supported regular release
