External MD Portal (Pathology Image Transfer Platform)

• Led development of a secure React + Next.js platform enabling external providers to upload and share multi-gigabyte pathology imaging datasets for second opinions and treatment planning.
• Architected multipart upload workflows across S3 and Azure Blob Storage, implementing custom queuing and concurrency logic to ensure reliable large-file transfers of 10–50GB datasets per session.
• Designed fault-tolerant upload retry mechanisms to reduce transfer failures and improve performance for multi-gigabyte image sets.
• Partnered with clinicians and infrastructure teams to ensure HIPAA-compliant data handling and secure external access.

Telemedicine Platform

• Lead frontend developer for a React-based telemedicine platform supporting 2,000+ daily patient visits.
• Developed real-time diagnostic tooling used by help desk teams to monitor live sessions, reducing average incident response time by ~35% and enabling faster resolution during patient consultations.
• Built a reusable React design system adopted across multiple internal applications, improving development velocity and UI consistency.

• Developed C++/Qt/QML frontend features for Surgimap surgical planning software used by spine surgeons worldwide for pre-operative simulation and parameter analysis.
• Improved DICOM communication workflows between planning software and PACS systems, increasing reliability of medical image transmission and storage workflows.
• Collaborated on interface layers between planning software and robotic arm control system.
