Ognomy Web App and Backend Performance Analysis

Key Information

The challenge is finished.

Challenge Overview

Challenge Objectives

To analyze and diagnose architecture issues that could affect the performance of the Ognomy ReactJS web application and its NodeJS based backend.

Project Background

  • We have built a suite of tele-office applications that allows patients to schedule and hold remote consultations with sleep specialists. The suite includes the patient-facing mobile app, the web application which is used by physicians and office-staff, and a common API and database. In this challenge, we are focusing on the web application, API, and DB.
  • Currently, the client is experiencing some performance issues on the web application.

Technology Stack

  • ReactJS
  • Javascript
  • CSS
  • HTML5
  • AWS
  • Backend uses Node.js and MongoDB

Code access & test environment

You’ll be provided the code as well as access to the deployment web app in our test environment.

Detailed requirements

In this challenge, we need you to:

  • Analyze the architecture of the API and the web app to find potential performance issues
  • Test & diagnose the api / web app to find potential performance issues
  • Document the process, tools, and results during your analysis and diagnosis
  • Provide recommendations on how to improve the api / web app performance
  • Include links to any tools used in this process or at least some text reference (for example: Lighthouse in Chrome Dev Tools)
  • NOTE: a lot of the performance issues may be coming from the backend, make sure you analyze the backend api carefully too.

A few things that you might find helpful:

  • The backend currently does all data encryption at application level, not at the database level, this is surely one of the areas to be looked into.
  • The backend also has some jobs that runs some analysis / aggregation on the data, which needs to be looked into as well.

What To Submit

Submit a detailed document in markdown or word format covering all the requirements above.
