Project Overview
Healthcare App
CasperEdge is a full-stack AI-powered platform designed to help students prepare for CASPer (Computer-Based Assessment for Sampling Personal Characteristics) tests. The platform combines interactive practice tests, real-time analytics, and intelligent feedback systems to help users improve communication, empathy, and situational judgment skills—core components of the CASPer exam.
Problem:
Healthcare App
Aspiring medical and professional school candidates often lack access to realistic CASPer test simulations and actionable feedback. Traditional preparation materials are static and fail to adapt to each learner’s performance, resulting in inefficient learning and limited progress tracking.
The client sought to build a comprehensive AI-driven preparation platform that not only replicates CASPer test environments but also provides personalized insights, progress monitoring, and a streamlined subscription experience.
Solution:
Our team developed CasperEdge, a fully integrated, AI-powered test preparation platform using modern technologies to deliver a smooth, scalable, and data-driven user experience.
Built with Next.js 15 on the frontend and a Node.js/Express backend, the system features a modular architecture that supports multiple user roles, AI feedback loops, and real-time performance analytics. AI capabilities were powered by Google Gemini, while Qdrant Vector DB provided high-performance embeddings and semantic search.
