What I'm looking for

I seek roles building scalable, secure HPC and MLOps infrastructure, focusing on automation, hybrid cloud integration, performance optimization, and collaborative research-to-production delivery.

I am a versatile systems engineer focused on designing and operating high-performance computing clusters, hybrid cloud infrastructure, and automated MLOps pipelines. I have built and managed GPU-accelerated AI/ML environments, deployed large-scale storage solutions (e.g., Dell EMC ECS, PowerScale, BeeGFS, Lustre), and automated infrastructure with Ansible, GitHub Actions and IaC tools to deliver reliable production and research platforms.

My experience spans enterprise and academic settings where I taught HPC concepts, supported scientific workloads, and integrated complex networking (Cisco, MikroTik, Mellanox) and security practices across on‑prem and cloud (AWS, Azure, OpenStack) environments. I prioritize scalable, secure, and observable systems with a strong focus on performance tuning, reproducibility (containers: Docker, Singularity/Apptainer), and user-oriented tooling such as Open OnDemand and SLURM Web UI.
