Versatile Engineer spanning cloud infrastructure, cybersecurity, networking, and AI/MLOps. I architect production-grade Kubernetes environments, build ephemeral GPU clusters for LLM workloads, and harden everything from the first commit to continuous deployment. Currently based in Tokyo, shipping infra for Offensive Security and building privacy-focused AI deployments through OpenZephyr.
Senior DevOps Engineer (LLM-Ops)
- ▸Architected ephemeral CUDA/Ollama Kubernetes infrastructure on AWS; reduced LLM provisioning to <30s via Packer AMIs.
- ▸Migrated 80% of core infrastructure (AWS/Cloudflare) to Terraform, automating networking and certificate lifecycle management.
- ▸Acted as technical liaison, aligning project requirements with C-suite stakeholders for high-impact business initiatives.
- ▸Developed Rust microservice to automate isolated GitLab environments with secure service accounts and OAuth tokens.
- ▸Standardized observability using Prometheus/Victoria Metrics/Grafana; managed vendor relations for monitoring infrastructure.
DevOps Engineer
- ▸Designed CI/CD pipelines and Celery automation to provision multi-cloud (AWS/Azure/GCP) VMs and containers on-demand.
- ▸Achieved 15% cost savings through infrastructure audits and seamless migration to open-source alternatives.
- ▸Developed Go-based Kubernetes operators, reducing EKS/CI-CD costs by 20% via optimized API and registry integration.
- ▸Accelerated SDLC by consolidating hundreds of redundant pipelines and automating security scans with Jira integration.
- ▸Streamlined container orchestration by migrating legacy Docker Swarm services to Kubernetes.
CloudOps / Compute & Security Engineer
- ▸Managed multi-cloud infrastructure (VMware/AWS) via APIs and IaC, optimizing datastores and network clusters.
- ▸Hardened network security using Snort IDS/IPS and Cisco firewalls; implemented VLAN segmentation and port mirroring.
- ▸Tier-3 security escalation for breaches/ransomware; conducted threat analysis and remediation to harden client posture.
- ▸Led end-to-end cloud migrations (consulting to production) for enterprise clients moving to AWS/Azure.
- ▸Optimized hybrid cloud connectivity (PaaS/IaaS/SaaS) using VPNs, reverse proxies, and Cloudflare Tunnels.
Network & IT Engineer
- ▸Enforced network access control via DHCP, private DNS, and MAC filtering on managed switches/routers.
- ▸Architected hybrid WFH infrastructure, including VPN/RDP access to Hyper-V, databases, and AD/AzureAD.
