🚀 Quick Start

Prerequisites

1. Install Deno:

   curl -fsSL https://deno.land/install.sh | sh
   

2. Configure API Keys:

   Groq (Recommended - Free & Fast)

   Uses LLaMA (Meta's open-source LLM) with Groq's high-performance inference API.

   export GROQ_API_KEY="gsk-your-groq-api-key-here"
   export GROQ_MODEL="llama-3.1-8b-instant"  # Optional - defaults to LLaMA 3.1 8B Instant
   

   Get your key: https://console.groq.com/keys

   Tavily (For Job Search)

   export TAVILY_API_KEY="your-tavily-key"
   

   Get your key: https://tavily.com

   OpenAI (Alternative)

   export OPENAI_API_KEY="sk-your-api-key-here"
   export OPENAI_MODEL="gpt-4o-mini"  # Optional - defaults to gpt-4o-mini
   

   Get your key: https://platform.openai.com/api-keys

   Note: Groq is recommended for development (free tier available). OpenAI is used as a fallback if Groq API key is not configured. Tavily is optional—without it, the app uses mock data for demonstration.

Running the Application

deno task run:server

Open http://localhost:8000 in your browser.

Note: The interface features a futuristic dark mode design with prominent animated gradients, glowing effects, and modern AI aesthetics. The design includes dynamic gradient animations (8-10s cycles), shimmer effects on the logo and "JobMatch AI" text (2s cycles), glowing borders, scanline overlays, and sophisticated glassmorphism effects for a cutting-edge user experience. The layout is optimized for desktop screens with drag-to-resize panels for side-by-side content.

Usage Flow

1. Add your resume (required for all features) - You can either:

   • Paste your resume text directly into the textarea, or
   • Upload a file using the "📄 Upload Your Resume - I'll Take It From Here!" button:
     • PDF files (.pdf) - Full support
     • Word documents (.docx, .doc) - DOCX fully supported, DOC with limited support
     • Text files (.txt) - Full support
   • Text will be automatically extracted and populated into the textarea
   • Button shows "✅ Upload Successful! Your Resume is Ready" after successful upload

2. Start JobMatch AI:

   • Click "🚀 Let's Get Started! I'm Ready to Help You Find Your Dream Job"
   • The resume input disappears with a smooth fade-out transition
   • Resume Strength Analysis appears on the left (runs automatically)
   • Job Search appears on the right (runs automatically without keywords)
   • Both features run simultaneously and display results side-by-side

3. Refine Job Search (optional):

   • Scroll down to see the "🎯 Refine Your Job Search" section
   • Enter optional keywords: Job Type/Role, Location, Additional Keywords
   • Click "🔍 Perfect! Let me find amazing opportunities that match exactly what you're looking for"
   • New job results appear in the scrollable wrapper above the refine section
   • Input fields clear automatically after search

4. Analyze Match & Generate Cover Letter:

   • Click "💼 Excited about a specific role? Share the job description with me and I'll dive deep into analyzing your perfect match, then craft a compelling cover letter that showcases your strengths!"
   • This button appears immediately but is disabled until the initial job search completes
   • Once enabled, click it to reveal a full-page job description input
   • Paste the job description and click "✨ Let's Do This! Analyze My Match & Create My Perfect Cover Letter"
   • Analyze Match results appear on the left
   • Cover Letter appears on the right with a copy-to-clipboard button
   • Both results are displayed side-by-side with resizable panels

5. Navigation:

   • Use "🔄 Found Another Great Opportunity? I'm Ready to Analyze It for You!" to analyze a different job
   • Use "🔁 Want to review your resume strengths or search more jobs? Let's jump back." to return to the main results view

Note: The interface uses progressive disclosure - features appear and disappear smoothly as you progress through the workflow. All content fits within one page with internal scrolling for job results and long content areas.

Technology Stack

Core Framework

• Zypher (@corespeed/zypher) - CoreSpeed's AI agent framework
• LLaMA (Meta's open-source LLM) - Large language model for intelligent analysis (via Groq)
• Groq API - High-performance inference provider for LLaMA (fast, free tier available, recommended)
• OpenAI API - Alternative LLM provider (fallback if Groq is not configured)
• Tavily API - AI-optimized web search with content extraction

Runtime & Language

• Deno - Modern TypeScript runtime
• TypeScript - Type-safe development
• RxJS (rxjs-for-await) - Reactive event streams

Additional Libraries

• pdf-parse - PDF text extraction for resume uploads
• mammoth - Word document (DOCX) text extraction

How It Works

1. Resume Input

   • Users can paste resume text or upload a file (PDF, Word, or TXT)
   • Files are automatically parsed to extract text content:
     • PDF: Uses pdf-parse library
     • Word (DOCX): Uses mammoth library
     • Word (DOC): Limited support, may require conversion to DOCX
     • TXT: Direct text extraction
   • Extracted text is populated into the resume textarea

2. Agent Initialization

   • Creates Zypher context and initializes model provider
   • Uses LLaMA (Meta's open-source LLM) via Groq inference API for fast, cost-effective analysis
   • Falls back to OpenAI if Groq API key is not configured
   • Configures streaming support for real-time responses

3. Analysis Pipeline

   • Structured prompt engineering for consistent JSON output
   • Streaming response processing with event accumulation
   • Post-processing: filters non-technical terms, validates skill matches, auto-corrects errors
   • Comprehensive error handling with detailed logging

4. Job Discovery

   • Tavily API searches web for relevant positions
   • Intelligent filtering by job board name (catches all domain variations: .com, .ca, .co.uk, etc.)
   • Automatically filters out 36+ job boards including LinkedIn, Indeed, Glassdoor, Eluta, Levels.fyi, Workopolis, and more
   • AI analysis ranks top 3 matches by resume fit
   • Returns structured results with match breakdowns

5. Resume Strength Analysis

   • Comprehensive resume quality assessment
   • ATS compatibility scoring
   • Identifies strengths, weaknesses, and improvement areas
   • Provides actionable suggestions for enhancement
   • Falls back to local parser if AI analysis fails

6. Cover Letter Generation

   • AI-generated personalized cover letters
   • Automatically extracts company name from job description
   • Tailored to match resume and job requirements
   • Outputs clean body text only (greeting and closing removed for simplicity)
   • Advanced cleanup to remove any prompt text or instructions
   • One-click copy to clipboard functionality

7. Resilience

   • Automatic fallback to local keyword-based parser on API failures
   • Graceful degradation maintains core functionality
   • Detailed diagnostic logging for troubleshooting

🐛 Troubleshooting

📋 Important Notes

• Default Behavior: LLaMA (Meta's open-source LLM) via Groq inference API is used if GROQ_API_KEY is set; otherwise falls back to OpenAI
• Skill Filtering: Only technical skills are analyzed (benefits, salary, etc. are excluded)
• Job Board Filtering: Filters by job board name (e.g., "glassdoor") to catch all domain variations (.com, .ca, .co.uk, etc.)
• Score Variance: LLM probabilistic nature may cause ±3-5 point variations (expected behavior)
• File Parsing:
  • PDF uploads extract all text content. Some formatting (tables, columns) may be simplified, but all text is preserved for analysis
  • Word DOCX files are fully supported
  • Word DOC files (older format) have limited support - conversion to DOCX or PDF is recommended
  • TXT files are directly extracted
• Multiple Operations: You can run multiple analyses or job searches - each new operation updates its respective results section
• Simultaneous Results: Analysis and job search results are displayed in separate sections and can be viewed simultaneously
• Cover Letter Format: Generated cover letters include only the body text (no greeting or closing) for maximum flexibility
• Diagnostic Logging: Server console includes detailed logging for API calls, errors, and response processing to aid in troubleshooting
