VPC architecture, Terraform IaC, CI/CD pipelines, agentic workflows. Deploy lead time under 8 minutes. - Brought production back from a full outage solo — navigated 8 cascading failures across the AWS stack overnight, patched each root cause as it surfaced, and handed off with a written incident report before morning. - Built a self-service portal that replaced a manual, ticket-based process for client network access — cutting provisioning from a multi-step back-and-forth to a flow users could complete themselves. - Automated the full client document cycle — from scoping to signed contract — cutting turnaround from 3 days to under 2 hours; milestone completion now triggers a pipeline that summarizes work, generates the document, routes it for signature, and notifies the team for approval, with no manual handling in between. - Took on sole lead of a client engagement with minimal documentation — mapped their entire multi-account cloud footprint from scratch, brought it under Terraform, and produced a written infrastructure baseline. Stack: AWS, Terraform, Docker, GitHub Actions, Traefik, Claude, Bedrock, VPC, IAM, S3, Lambda, DynamoDB, CloudFront, WAF, CloudWatch Metrics: Dev/staging/prod environments owned. Deploy lead time under 8 minutes. ### Applied Research Engineer — Aqsacom (2023–2024, Dallas TX, Remote) Wireless sensing and indoor positioning research. Sub-meter accuracy using BLE and WiFi RSSI-CSI sensor fusion benchmarked against UWB hardware baseline. PyTorch signal processing pipelines. AoA/AoD direction-finding. - Engineered real-time indoor positioning engine achieving sub-meter accuracy using BLE/WiFi RSSI-CSI sensor fusion. - Implemented AoA/AoD direction-finding on BLE hardware for spatial signal inference. - Developed PyTorch signal processing pipelines for CSI feature extraction, model training, and real-time inference. - Benchmarked NFC and UWB chipsets for proximity detection latency and accuracy. Stack: Python, PyTorch, NumPy, BLE, WiFi CSI, UWB, NFC ### Software Engineer — Aqsacom (2021–2022, Dallas TX, Remote) Enterprise PHP applications on Zend Framework and MySQL. NGINX fronting Apache. Ubuntu server operations. Sole remote engineer with full delivery and ops ownership. Stack: PHP, Zend, MySQL, NGINX, Apache, Ubuntu ## Projects ### Serverless CMS Platform (2026) Hard constraint: operate under $15/month without sacrificing a real CMS, responsive storefront, or production auth. Static Next.js export on S3 + CloudFront for the public frontend; Vite SPA for the admin panel; seven Lambda functions behind API Gateway; DynamoDB single-table design; SES + SSM for magic-link auth. 61 automated test files. Stack: Next.js, Lambda, API Gateway, DynamoDB, SES, SSM, CloudFront, Terraform, GitHub Actions, OIDC, WAF ### Time Series Transformer MLOps Pipeline (2026) End-to-end automated retraining and inference pipeline for multivariate time series. Model: PatchTST — channel-independent Transformer with patch-based tokenisation, 8 independent prediction heads, ~500k parameters. S3 PutObject triggers EventBridge → Step Functions orchestrates EC2 Spot (g4dn.xlarge) training → Lambda runs inference → CloudWatch captures structured metrics. All infrastructure in Terraform. Property-based tests with Hypothesis. Stack: PatchTST, PyTorch Lightning, Step Functions, EC2 Spot, Lambda, EventBridge, Terraform, Hypothesis ### EKS Platform — Karpenter and GPU Scheduling (2026, PoC / decommissioned) Kubernetes platform on EKS built around Karpenter for node provisioning and GPU workload scheduling. Karpenter handles node lifecycle — provisioning GPU instances on demand, consolidating underutilised capacity, respecting topology constraints. Qdrant as vector store with hybrid dense and sparse retrieval. Built to validate operational tradeoffs of self-managed Kubernetes ML workloads vs. managed alternatives. Stack: EKS, Karpenter, GPU scheduling, Qdrant, Kubernetes, RAG, vector search ### Resume Infrastructure (2026) S3 + CloudFront + WAF static site with OIDC-based GitHub Actions deploy. Playwright generates A4 and Letter PDFs in CI. Shared Terraform module for prod and staging environments. Zero long-lived credentials. Deploy lead time under 5 minutes. Stack: S3, CloudFront, WAF, OAC, Terraform, GitHub Actions, OIDC, Playwright, Vite, React ### WiFi CSI Pose Estimation — Reproduction Study (2024) Rebuilt the test environment from the CMU DensePose-from-WiFi paper to validate its claims independently. Results did not reproduce consistently — reported conditions appeared to reflect a narrow slice of the experimental space. Findings written up as internal technical documentation. Stack: WiFi CSI, PyTorch, Research, Reproducibility ## Education B.S. Computer Science — Middle East University, Beirut (2021–2025). GPA 3.83.
