Senior Infrastructure & AI Engineer specializing in AWS, automation, and reliable operations.
IsraelWhat I'm looking for
I’m a Senior Infrastructure Engineer / AI Engineer with a Computer Science background and 10+ years across IT infrastructure, systems administration, monitoring, troubleshooting, automation, and operational reliability. My core strength is building repeatable, secure workflows across Windows and Linux environments.
In my current hands-on work, I combine AWS-based cloud and web platform components with GitHub Actions CI/CD using AWS OIDC for keyless AWS auth. I deploy and operate AWS Lambda + Step Functions, build Docker workflows, and support Docker-based CI/CD structures, while also contributing to reliable deployment structure and operations.
I also develop Node.js/Express backend service components—REST API flows, validation, JSON contracts, JWT/access-control, structured logging, and API testing. Alongside engineering, I build AI-assisted workflows using task-specific agents and LLM tools to support debugging, research, refactoring, and documentation—while keeping technical review, security, and operational responsibility human-owned.
Earlier, I owned Windows-based infrastructure in an NGO environment, including 15+ workstations, NAS/Synology storage, VPN, access control, and backup/DR practices. I automated repeatable operations with Bash/CMD/VBA, improved security hygiene and digital hygiene, and documented support workflows—always with a reliability-first mindset.
Experience
Work history, roles, and key accomplishments
• Built a GitHub Actions CI/CD pipeline deploying AWS Lambda + Step Functions using GitHub OIDC federation for keyless AWS auth (short-lived STS credentials, least-privilege IAM) — removing all long-lived access keys.
• Work across cloud architecture and infrastructure/backend integration: AWS compute, networking, storage, serverless and monitoring; contribute to deployment structure and operation
Project / Scope: Infrastructure modernization and operational support for an NGO environment, focused on reliability, backups, access control, security hygiene and repeatable support automation.
Infrastructure Operations: Owned Windows-based environment, 15+ workstations, NAS/Synology storage, VPN, cloud PBX, user access, licensing, hardware/software troubleshooting and vendor communication.
