PROFILE

Katarzyna Fojcik

Katarzyna Fojcik contributed to HabanaAI/vllm-fork and Gaudi-based vllm repositories by engineering robust solutions for long-context model inference and deployment stability. She enhanced prompt bucketing logic to support large-context queries, enabling dynamic generation of context buckets and improving scalability for high-capacity input handling. In parallel, she addressed device-specific model loading and optimized RotaryEmbedding cache management, reducing runtime errors and supporting LoRA experimentation. Her work, implemented in Python and PyTorch, demonstrated strong backend development and data processing skills, with careful attention to code quality, cross-repository consistency, and production readiness, resulting in more reliable and flexible machine learning workflows.

January 2026 focus: deliver cross-repo enhancements to long-context prompt bucketing for large-context queries, enabling generation of missing buckets up to max context length and improving performance and scalability. Achievements span two Gaudi-backed repos with aligned logic via cherry-pick, validated bucket-generation flow, and strong commit hygiene across teams. Business impact includes higher input capacity, reduced edge-case failures, and a foundation for future context expansion.

Monthly summary for 2025-08: In HabanaAI/vllm-fork, delivered two high-impact bug fixes that improve deployment stability and inference correctness. The changes ensure correct device loading for weights (--weights-load-device) and robust cos-sin cache handling in RotaryEmbedding for long contexts and LoRA offsets. Together, these fixes enhance production readiness, reduce runtime errors, and support reliable long-context and LoRA experimentation.
