Operate a four-node cluster (k8s v1.33) of Talos Linux VMs, hosted on Proxmox, with no routine manual kubectl apply — every change ships through Git review and FluxCD reconciliation. Ceph RBD storage, HA PostgreSQL via CloudNativePG, SOPS+age encrypted secrets, Traefik/MetalLB with keepalived HA, internal ACME CA. Maintains a written disaster-recovery runbook and has recovered real incidents, with the analyses recorded in the commit history.

Platform & Infrastructure Engineer · AUB CCE '26 graduate
Summary
Engineering graduate (B.E. Computer & Communications Engineering, AUB, 2022–2026) who builds and operates real infrastructure end to end: a self-run Kubernetes cluster on Talos VMs driven entirely by GitOps, cloud-native backends, Ansible/Terraform automation, and a completed adversarial-ML research capstone. Comfortable working independently (mobile → API → database → CI/CD → deployment) and inside other teams' codebases and review processes.
Selected projects
Full evidence-checked inventory (~30 repos) at orski.sh
Built and evaluated adversarial-robustness defenses (FGSM, PGD, Carlini-Wagner, patch attacks; ResNet18/WideResNet) plus an original "adversarial routing" detector that flags likely-adversarial inputs. ~16.5K lines of PyTorch/Optuna research code; SLURM scripts were written for the university HPC cluster, with the large sweeps run on Colab and a local GPU. Paired with a FastAPI + React/Vite dashboard (~2.5K lines) for live inference, model configuration, and evaluation. Patch-route calibration remained an open item at submission.
Kotlin/Jetpack Compose Android app streams cellular telemetry to a FastAPI + PostgreSQL backend (JWT/OAuth2, per-IP rate limiting). Runs on PostgreSQL, with a 359-line pytest suite exercised against in-memory SQLite. Ships a CI pipeline producing signed release APKs and Docker images, and a Helm chart for k8s rollout. 4,049 LOC total.
Six Express microservices with polyglot persistence mirroring AWS semantics (Postgres, DynamoDB with TTL, async S3+SES+SQS invoice pipeline), backed by 3,508 lines of Terraform standing up matching ECS/IAM/ECR/DynamoDB infrastructure with OIDC-based GitHub Actions deploy roles. I built the services and most of the Terraform; a teammate built the React frontend and its deploy pipeline. Built in a 5-day sprint.
Designed and built two Ansible roles from scratch — cobbler_pxe (full PXE/DHCP/DNS provisioning, a 228-line design doc, idempotent config patching, and a four-file test suite: one pytest orchestrator plus three Ansible smoke playbooks) and nginx — plus restored a vaultwarden role and authored a PXE-boot-testing automation skill. Thirty-five of my commits are merged into the owner's main branch.
Solo-built 11 Ansible roles / 11 playbooks provisioning a complete self-hosted GitLab stack (libvirt/KVM, Docker, Traefik, WireGuard, PXE). Separately, added OCI image support (pull + push) and PXE-boot via a new BareVM provider inside a mentor's Python tool, both merged upstream, with tests and documentation.
Experience
Regular contributor to a research-computing colleague's multi-author infrastructure repos: designed roles and subsystems from written proposals through to tested, documented, merged code (see Selected Projects).
Triaged bugs and gave feedback on ShokoServer and related projects; forked and adapted several Jellyfin plugins to personal use cases.
Archived university data from social media platforms. Researched archiving approaches for Instagram, Facebook and Twitter, then built a Python/Selenium + Java + Go scraping toolkit (packaged as standalone executables) that replaced manual scraping with an automated pipeline.
Tutored children in using LEGO robotics kits; helped translate technical concepts for a young audience and supported small group projects.
Invoice processing and validation, product checking and shipping.
