PROFILE

Piotr Januszewski

During two months on NVIDIA-NeMo/Eval, Piotr Januszewski developed scalable launcher and deployment configurations, focusing on usability and reproducibility for model evaluation and serving. He introduced YAML-based Slurm launcher setups for Llama 3.1 8B Instruct with vLLM, migrated launch commands to a new eval-factory interface, and delivered a deployment-ready TensorRT-LLM serving configuration with Docker integration and defined API endpoints. Using Python, YAML, and configuration management skills, he enhanced CLI argument parsing, improved API payload handling with recursive parameter removal, and consolidated documentation. His work addressed onboarding friction, improved developer experience, and ensured robust, maintainable backend and DevOps workflows.
