PROFILE
Peter Polacik
Over six months, contributed to the wundergraph/cosmo repository by delivering twelve features and resolving critical bugs focused on platform stability, security, and deployment reliability. Work included backend enhancements such as authentication error handling, dual-write blob storage for data resilience, and migration from MinIO to RustFS for improved S3 compatibility. Applied security patches to dependencies like AWS SDK and js-yaml, modernized containerization with rootless Docker images, and upgraded frontend frameworks using TypeScript, Node.js, and Next.js. Emphasized maintainability through dependency management, Helm-based deployments, and code ownership updates, resulting in a more robust, secure, and maintainable cloud-native platform architecture.
