Overview

At New York Web Studios, I developed healthcare system integrations and a custom electronic signature platform, enabling secure data exchange and streamlined documentation workflows across medical systems. The solution focused on interoperability, compliance, and workflow automation within healthcare environments.

The Problem

Disconnected medical systems with limited interoperability

Manual and inefficient documentation workflows

Lack of secure, compliant electronic signature solutions

Complexity in integrating with legacy healthcare systems

Strict regulatory requirements (HIPAA, auditability)

The Solution

Integrated healthcare systems using HL7 and FHIR standards

Developed custom electronic signature solution for medical documentation

Designed HIPAA-compliant architecture for sensitive data handling

Built APIs for standardized system communication

Connected legacy systems with modern applications
