PROFILE

Joachim

During a four-month period, Jakub Bartosik developed and integrated advanced autoscaling and observability features for Kubernetes environments in the DataDog/datadog-agent and DataDog/datadog-operator repositories. He implemented PodDisruptionBudget collection and orchestrator RBAC updates, enabling real-time disruption visibility and stable upgrades. Jakub upgraded the DatadogPodAutoscaler Custom Resource Definition, introducing new scaling policies and a CustomQuery objective for metric-driven autoscaling. His work involved end-to-end API development, CRD design, and system programming in Go, with a focus on distributed systems and Kubernetes API compatibility. Each feature was delivered with careful attention to validation, migration, and operational safety, reflecting strong engineering depth.

Sep 1, 2025

September 2025 monthly summary for DataDog/datadog-operator: Delivered a new CustomQuery autoscaling objective for DatadogPodAutoscaler, enabling autoscale decisions based on specific Datadog metric queries. This required updating validation annotations and deepcopy logic to support the new CustomQuery type, ensuring Kubernetes API compatibility and safer deployments. Focused on implementing a high-value feature that enables more precise scaling decisions and improves resource utilization. No additional major features or bugs were closed this month beyond the CustomQuery work; the team concentrated on solidifying the feature integration and validation across the operator.
