Reach VR
Full Stack Developer — Backend (Node.js/Rust/WASM), Database, AWS Infrastructure, CI/CD, Unity support
Overview
I worked on the backend services, real-time data processing pipeline, and cloud infrastructure for a VR game that helps people recover from frozen shoulder. Patients play on Meta Quest at home while clinicians monitor their progress through a dashboard.
Architecture
Backend on Node.js/Express with MySQL for patient and session data. Performance-critical motion calculations run in Rust/WASM via WebWorkers. Infrastructure on AWS with Jenkins for CI/CD. I also supported Unity integration for backend services and data streams.
Technical Challenges
Main challenges were calculating patient movements in real-time without overloading the server — receiving multiple data points and computing the patient's current state compared to historical data. Ensuring data accuracy and calculations for real clinical studies. Making each game both fun and clinically useful.
Outcome
Backend systems up and running — real-time gameplay adaptation, dashboards for clinicians, and remote monitoring all working together. Patients do their rehab exercises at home while clinicians track their progress over time.
