Description

This project was to create a mobile-web-app to provide record-keeping-service of blood pressure measurements and to display them in a table and graphs.

I played the role of designer, frontend developer, and backend developer, which means I carried out the project alone.

Users can download and install the app by browser's PWA functionality boosting clientside performance.

Since this app deals with sensitive data related to personal privacy, this app implements a couple of strong security features:

• AWS SES is used to authenticate users
• WebAuthn(a.k.a passkeys), a relatively new web-standard, is used to authorize users
• QR code is used to add friends who will act as an attorney-in-fact or an observer in the app

Backend is writen in Rust for blazingly fast performance and lowering the change of errors by RAII. Backend server is configurable without changing codes with configuration files.

Docker is used for consistency, portability, CI/CD and version control.

Opentelemetry tracer is used to increase observility and Jeager is used to gather/store/display tracing data.
