PROFILE
Sanjay Chatterjee
Sanjay Chatterjee developed and enhanced Kubernetes scheduling features across the NVIDIA/grove and NVIDIA/KAI-Scheduler repositories, focusing on scalable resource management and improved onboarding. He overhauled Grove’s documentation in Markdown to clarify architecture and accelerate user adoption, and implemented a PodGangs Scheduler Plugin in Go, introducing new custom resources and RBAC configurations. Sanjay enabled dynamic auto-scaling by refining validation logic and expanded RBAC permissions to support secure, owner-referenced workflows. He also delivered API rename compatibility, updating system design and plugin registration to ensure smooth transitions for users. His work emphasized maintainability, reliability, and seamless integration within cloud-native environments.

Sep 1, 2025September 2025: Delivered Grove API rename compatibility for KAI-Scheduler, aligning PodGangSet to PodCliqueSet, with updates to RBAC configurations and plugin registrations to reflect the new API naming and ensure compatibility with PodCliqueSet resources. This work reduces upgrade risk, preserves backward compatibility during transition, and improves scheduling reliability for PodCliqueSet workloads.

Jul 1, 2025July 2025 — NVIDIA/KAI-Scheduler: Key features delivered include (1) flexible auto-scaling across Grove clique level by removing a validation that enforced equal MinReplicas across PodGroups within a PodGang, enabling dynamic scaling and faster workload responsiveness; (2) RBAC enhancement for PodCliqueScalingGroup resources to support owner-reference scenarios, ensuring proper access control for Grove PodCliques. Overall impact: improved scaling responsiveness and resource utilization, strengthened security posture, and smoother operator workflows. Technologies demonstrated: Kubernetes RBAC, owner-reference workflows, dynamic autoscaling architectures, and PodGang/PodClique scaling models.

Jun 1, 2025June 2025 monthly summary focusing on business value and technical delivery: Delivered a comprehensive Grove README overhaul to improve onboarding and clarity of Grove's purpose and architecture (Kubernetes operator and scheduling API), core concepts, use cases, installation, and community engagement, with visuals to illustrate use cases and accelerate onboarding. Implemented Grove PodGangs Scheduler Plugin for NVIDIA/KAI-Scheduler, introducing PodGangSet and PodClique resources with RBAC configurations, new grouper logic, and unit tests to ensure reliability and maintainability. No high-severity defects reported; primary work focused on feature delivery and documentation enhancements. Impact: faster onboarding, clearer architecture, and more capable scheduling with tests to reduce regressions. Technologies/skills: Kubernetes operator patterns, scheduler plugin architecture, RBAC, unit testing, grove.io API, and improved documentation.
