Project Overview

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.

Key Features

• 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

Core Framework

• 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

Styling & Components

• 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

Data Visualization

• Recharts 2.15 - Composable charting library used for bar charts, pie charts, and analytics visualization

Forms & State

• 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)

Additional Features

• React Resizable Panels - Dynamic panel resizing for flexible layouts

• Date-fns - Date manipulation and formatting utilities

• Embla Carousel - Accessible carousel components

Backend Architecture

• 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)

This Approach:

• 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

Why These Features?

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

Key Takeaway

CareerOS is a production-ready application that demonstrates full-stack frontend capabilities: from component architecture and state management to responsive UI and real-world problem solving. It shows proficiency with modern React, TypeScript, and the tools used by professional development teams.
