EMS Handoff Dashboard - Logical Architecture (Development In-Progress)

In high-volume emergency departments, clinicians often operate within a critical information vacuum regarding incoming ambulance traffic. Currently, hospital staff have no visibility into the number of incoming patients or their specific medical complaints unless a patient is "actively coding". This lack of data leads to reactive resource bottlenecks and staffing surges only after patients arrive. I designed this real-time dashboard to eliminate this blind spot, providing the "luxury of anticipation" by transforming incoming dispatch data into actionable insights. This allows clinical leadership to proactively allocate staff and resources, ensuring the department is prepared well before the ambulance reaches the emergency department doors.

Logical Architecture and Technical Flow

• Data Ingestion: Dispatch data is securely processed via Azure API Gateway and Azure Functions, providing an entry point for real-time patient updates.
• Scalable Persistence: Data is committed to Azure Cosmos DB, partitioned by ED-ID to ensure high performance and strict data isolation across multiple emergency department sites within the hospital system.
• Real-Time Push Logic: A Change Feed Processor triggers a secondary function upon successful data entry, which utilizes Azure SignalR to push instantaneous updates directly to the hospital-facing dashboard.
• Outcome: By introducing real-time visibility where an information vacuum previously existed, clinical leadership gains a zero-latency view of incoming volume and acuity — transforming a reactive, blind intake process into a proactive, event-driven workflow.

Technical Stack: Azure Functions, CosmosDB, SignalR, API Gateway, PowerShell, Python

Azure Resource Janitor Script

Developed a comprehensive automation suite to manage cloud sprawl and optimize subscription costs by identifying and decommissioning unused Azure resources. This project addresses the common challenge of "ghost costs" associated with unattached disks and abandoned testing environments.

Technical Stack: PowerShell, Azure, Git, GitHub, Cloud Governance & Cost Management Logic

Personal Cloud Resume Website Deployment

This Cloud Resume Project demonstrates full-stack cloud proficiency by hosting a static HTML/CSS/JavaScript frontend on AWS S3, delivered globally via CloudFront and secured with Route 53/ACM. A serverless Python Lambda function, exposed via Amazon API Gateway, leverages DynamoDB for a dynamic visitor counter. The entire architecture showcases skills in cloud infrastructure, serverless development, secure web delivery, and automated CI/CD with Git/GitHub.

Technical Stack: HTML, CSS, JavaScript, Amazon S3, CloudFront, Route 53, AWS ACM, Python Lambda, Amazon API Gateway, Amazon DynamoDB, AWS IAM, Git/GitHub, CI/CD

PowerShell Automation Scripts for IT Operations

Developed a collection of PowerShell scripts to automate common IT operational tasks. For one task, created a comprehensive system administration menu script providing a user-friendly interface for file management and real-time system monitoring (CPU/memory usage, process lists). For a second task, developed targeted automation scripts for infrastructure management: one for Active Directory to handle the recreation of organizational units and bulk user provisioning from a CSV, and another for SQL Server to automate the complete restoration of a database, including table creation and data import.

Technical Stack: PowerShell, Active Directory, SQL Server, Windows Server Administration
