PROFILE
Lennart Kloock
Lennart contributed to the ScuffleCloud/scuffle repository by architecting and delivering core authentication, streaming, and dashboard features for a scalable media platform. He implemented secure workflows such as WebAuthn, TOTP, and session management, integrating Rust, TypeScript, and SQL to support passwordless login, MFA, and robust user onboarding. Lennart refactored the RTMP/FLV streaming stack, enhanced HTTP/3 error handling, and introduced Diesel ORM-backed APIs with CORS and OpenTelemetry tracing. His work included policy enforcement with Cedar, gRPC-Web support, and dashboard session lifecycle improvements. The engineering depth is reflected in maintainable code, comprehensive test coverage, and seamless integration of backend and frontend systems.
