Technical Solutions Developer – Cloud Infrastructure, Linux Internals & AI Supercomputing
Apr 2022 – Present · Kitchener, ON
- Enterprise Escalation Leadership & Reliability: Serve as primary technical escalation lead and North America SME for Enterprise Linux (RHEL, SLES, Rocky Linux), resolving mission-critical P0/P1 production outages for Fortune 500 financial, retail, and AI enterprises; maintained a 100% initial response and consultation SLA, 0% case reopen rate, and 90% valid engineering defect escalation rate across 350+ annual engagements.
- AI Supercomputing & Large-Scale GPU Diagnostics: Lead infrastructure troubleshooting for frontier AI/ML workloads across 256-GPU NVIDIA H100 (A3 Mega) and liquid-cooled NVIDIA GB200 NVL72 (A4X Max) clusters; resolved distributed PyTorch/NCCL collective hangs over GPUDirect-TCPXO, CUDA PTX JIT driver regressions, NVLink switch fabric degradations, and Managed SLURM root-disk exhaustion.
- Kernel Driver Backporting & High-Stakes Event Protection: Guaranteed 100% production uptime for a global quantitative trading platform during a major IPO event by diagnosing hypervisor live-migration drops to an Admin Queue retry flaw in legacy gve 1.0.0 network driver; engineered custom Linux kernel C source patch (gve 1.3.1 backport) for EOL CentOS 7.9 (3.10 kernel) alongside emergency maintenance freezes.
- Large-Scale Fleet Migration & Systems Profiling: Unblocked a multi-thousand-node fleet migration to Rocky Linux 9 (Kernel 6.1) for a Tier-1 market maker after simulation jobs experienced 90x latency spikes (30s to 45m); profiled kdump memory cores, maps, and strace D-state traces to isolate a boot-time systemd bound race condition diverting NVMe scratch I/O to NFS, partnering with Principal Engineers to resolve CPU L1 cache contention.
- Cloud Security Architecture & Disaster Recovery: Guided an international financial institution through Confidential Computing (vTPM attestation) and VPC-SC perimeter architecture across Shared VPC boundaries; recovered unbootable enterprise SLES production nodes via raw block-level cloning and chroot UEFI/GRUB shim reconstruction, ensuring zero data loss across clustered RAID storage during hypervisor live-migration loops.
- Technical Enablement & Mentorship: Authored 7+ internal engineering playbooks and public Google Cloud documentation guides covering HPC Cluster Toolkit/SLURM diagnostics, MIG autohealing, IAM service accounts, and serial console recovery; formally mentored 5+ engineers transitioning into cloud compute infrastructure.
