A Web-Based Job Application Status Tracker
CareerOS is a full-featured web application that simplifies job search management by centralizing application tracking, interview scheduling, and progress analytics into one intuitive dashboard. Built as a single-page application with React and TypeScript, it demonstrates modern frontend development practices and responsive UI/UX design. The demo is hosted on Vercel and available for user testing.
Problem Solved:
Job seekers typically juggle multiple applications across different platforms, making it difficult to track progress, manage interview schedules, and analyze their success rate. CareerOS consolidates all this information in one organized system.
Application Dashboard - View and manage all job applications with real-time status updates
Interview Timeline - Schedule and track interviews with notes, dates, and outcomes
Analytics & Insights - Visual charts showing application conversion rates, status distribution, and response metrics
Status Tracking - Monitor each application from "Applied" → "Interview" → "Offer/Rejected"
Responsive Design - Fully functional on desktop, tablet, and mobile devices
Dark Mode - Complete dark mode support for all-day usability
Demo Account - Explore with pre-loaded sample data without creating an account
React 18.3 - Component-based UI library with hooks for state management and side effects
TypeScript - Ensures type safety across the entire codebase, catching errors at compile time
Vite 6.3 - Next-generation build tool providing lightning-fast development server and optimized production builds
React Router 7.13 - Client-side routing for seamless page navigation without server requests
Tailwind CSS 4 - Utility-first framework for responsive, maintainable styling
Radix UI - Unstyled, accessible component library (modals, dropdowns, tables, accordions)
Lucide React - Modern, consistent SVG icon set
Sonner - Toast notification system for user feedback
Recharts 2.15 - Composable charting library used for bar charts, pie charts, and analytics visualization
React Hook Form - Efficient form management with validation and minimal re-renders
React Context API - Global state management for authentication and application data (ApplicationContext, AuthContext)
React Resizable Panels - Dynamic panel resizing for flexible layouts
Date-fns - Date manipulation and formatting utilities
Embla Carousel - Accessible carousel components
Architecture Pattern: Client-Side Rendering (SPA)
While this project is frontend-focused, the architecture demonstrates understanding of application state management:
Context-Based State Management - React Context API manages global authentication and application state
Local Storage Persistence - User data persists across sessions using browser's LocalStorage API
Stateless Component Design - Functional components with hooks follow modern React patterns
No External API Dependency - Fully self-contained frontend enables deployment to static hosting (Vercel)
Demonstrates understanding of state management without external dependencies
Enables instant deployment with zero backend infrastructure
Shows proficiency with React Context and data flow patterns
Provides a fast, responsive experience with client-side processing
If I were to continue developing CareerOS, here are the features I would prioritize:
Data Management
Import/Export Functionality - Allow users to export their application data to CSV for spreadsheet analysis and PDF for archival purposes. Import existing application data from CSV files to quickly migrate from other tools.
Backup & Restore - Automated backup system to prevent data loss and enable restoration across devices
Integration & Automation
Calendar Integration - Sync interview dates with Google Calendar, Outlook, or iCal with automatic reminders
Email Notifications - Automated reminders for upcoming interviews, follow-ups, and application deadlines
Job Board API Integration - Pull job listings directly from LinkedIn, Indeed, and other platforms to streamline the application process
Browser Extension - Quick-add Chrome/Firefox extension to save job postings while browsing
Advanced Features
Document Tracking - Associate resumes, cover letters, and portfolios with each application to track which versions were sent where
Company Research Hub - Integrate Glassdoor ratings, salary data, and company news to make informed decisions
Networking Tracker - Manage contacts, referrals, and networking connections related to each application
AI-Powered Insights - Resume optimization suggestions, job match scoring, and personalized application tips
Backend & Scalability
Full Backend Implementation - Migrate from LocalStorage to a Node.js/Express backend with PostgreSQL or MongoDB for persistent, scalable data storage
User Authentication - JWT-based authentication system with password recovery and multi-factor authentication
Multi-Device Sync - Real-time data synchronization across desktop, mobile, and tablet devices
Collaborative Features - Share applications and progress with career coaches, mentors, or job search partners
User Experience
Advanced Analytics - Time-to-offer metrics, A/B testing for resume versions, application success rate by industry/role
Custom Tags & Filters - User-defined categories, priorities, and custom fields for personalized organization
Mobile App - Native iOS/Android app for on-the-go application management
Accessibility Improvements - Screen reader optimization, keyboard navigation enhancements, and WCAG AAA compliance
These enhancements demonstrate:
Product Thinking - Understanding user pain points and prioritizing features that add real value
Technical Depth - Awareness of integration patterns, data management strategies, and scalable architecture
Full-Stack Vision - Knowledge of how frontend features connect to backend infrastructure
User-Centric Design - Focus on improving the job search experience from multiple angles
