Petr Vanek developed end-to-end sandbox telemetry and resource governance for the e2b-dev/infra repository, focusing on real-time host statistics collection and performance monitoring. Leveraging Go and ClickHouse, he integrated per-sandbox cgroup v2 resource accounting, including interval-based memory.peak tracking and CLONE_INTO_CGROUP usage to prevent race conditions. Petr enabled ClickHouse analytics for local development, improving testing fidelity and observability. He enhanced deployment security by adding SELinux-compatible Docker Compose volume mounts and improved build automation through Makefile reliability fixes. His work addressed debugging efficiency, resource management, and CI stability, demonstrating depth in backend development, system programming, and DevOps practices.
February 2026: Implemented end-to-end sandbox telemetry and resource governance, stabilized builds, and strengthened deployment security. Key capabilities include per-sandbox host statistics collection and real-time performance monitoring, per-sandbox cgroup v2 resource accounting (CPU and memory) with interval-based memory.peak tracking and CLONE_INTO_CGROUP usage to avoid race conditions; enabled ClickHouse for local development analytics. Added SELinux-compatible Docker Compose volume mounts for secure deployments. Build system reliability improvements with Makefile fixes (generate-target/PHONY declarations) and corrected E2B CLI environment variable naming. Overall, this work increases observability, enforces finer-grained resource governance for sandboxes, accelerates debugging, and strengthens security and CI stability.
