Finder

AI-Powered Career Intelligence Platform & Job Portal

Finder is an open-source platform that analyzes candidate resumes, extracts structured career profiles, and recommends matching job opportunities through an interactive, chat-first workspace.

Unlike traditional job boards that require users to search through raw keyword listings, Finder acts as a personal AI career advisor. Candidates upload their resume (PDF), which the system analyzes using Groq-accelerated models (qwen/qwen3.8-27b, fallback openai/gpt-oss-20b). The platform identifies core strengths, detects skill gaps, curates matching active jobs via a resilient two-stage matching pipeline, and provides an interactive Career Copilot for technical interview preparation.

Key Features

Document Parsing & Text Extraction: Drag-and-drop PDF resume upload with magic bytes verification (%PDF-), text extraction via pdf-parse, and storage in private Supabase buckets.
AI Candidate Profiling: Structured profile extraction powered by Groq (qwen/qwen3.8-27b / Prompt v2.7, fallback openai/gpt-oss-20b) into candidate skills, experience, education, and career level.
Two-Stage Job Matching Engine:
- Stage 1 (Deterministic): SQL skill-overlap pre-filter (limit 25) + weighted pre-ranking (Core: 2.0x, Supporting: 1.2x, General: 1.0x) to select the top 5 candidates.
- Stage 2 (Deterministic Re-score): Finder recomputes the final score deterministically from skill overlap and profile evidence, so the model never overrides the ranking.
Conversational Career Copilot: Real-time multi-turn career consulting streaming via Server-Sent Events (SSE), pre-grounded with candidate strengths and active job requirements.
Job Discovery & Detail Drawer: Curated job listings view with interactive match level, experience, and location filters, paired with an accessible WAI-ARIA detail drawer.
Dual Authentication (Web2 + Web3):
- Standard email and password authentication with Supabase SSR session cookies.
- Cryptographic Sign-In with Sui (SIWS) personal message verification with in-memory challenge nonces and synthetic account abstraction.
- Sui Wallet linking and unlinking with unique address constraints.
Automated External Job Ingestion: Scheduled job synchronization from Remotive API secured with timing-safe constant-time secret comparison.

Prerequisites

Node.js: 22.x or later. Verify with:
```
node -v
```
npm: 10.x or later.
Supabase Account: A Supabase project with PostgreSQL database and Storage.
Groq API Key: Free API key from Groq Console. For active model choices, see Groq Supported Models.

Quick Start

1. Clone & Install Dependencies

git clone https://github.com/DafinCi/Finder.git
cd Finder
npm install

2. Configure Environment Variables

Copy .env.example to .env.local:

cp .env.example .env.local

Fill in your configuration:

# Supabase
NEXT_PUBLIC_SUPABASE_URL=https://your-project.supabase.co
NEXT_PUBLIC_SUPABASE_ANON_KEY=your_anon_key
SUPABASE_SERVICE_ROLE_KEY=your_service_role_key

# Groq AI (Active models: https://console.groq.com/docs/models)
GROQ_API_KEY=gsk_your_groq_api_key
GROQ_MODEL=qwen/qwen3.8-27b
GROQ_FALLBACK_MODEL=openai/gpt-oss-20b
GROQ_MAX_TOKENS=2500

# Application Base URL
NEXT_PUBLIC_SITE_URL=http://localhost:3000

# Sui Web3 Network
NEXT_PUBLIC_SUI_NETWORK=mainnet

# Cron Sync Secret (optional in development)
CRON_SECRET=your_cron_secret

3. Setup Database & Storage

In your Supabase project dashboard, open the SQL Editor.
Run src/database/schema_v2.sql to create all tables, indexes, and RLS policies.
Optional, for local demos only: run src/database/seed-demo.sql to add clearly marked sample companies and jobs. Skip this on production.
Run src/database/triggerAuth.sql to create the automated profile trigger.
In the Storage dashboard, create a private bucket named resumes.

4. Start Development Server

npm run dev

Open http://localhost:3000 in your browser.

Data Handling & Privacy

Resumes are stored privately in Supabase Storage and are never published to Walrus.
Resume text is sent to Groq for extraction and matching. Groq is a third-party processor, so review your own compliance needs before real user data flows through it.
Career memories live in Supabase and on Walrus through Walrus Memory. Walrus blobs are public by default, and Walrus Memory encrypts their contents with Seal so only the owner and authorized delegate keys can read them.
The optional public career passport contains only skills, target roles, employment types, and career level. It excludes name, contact details, education, employers, salary, location, and account identifiers, and it publishes only after explicit confirmation.
Forget hides a memory from chat recall and marks it forgotten in the database. It does not delete the encrypted blob already written to Walrus. Permanent blob deletion requires a separate deletion flow.
Server logs record operational metadata such as IDs, model names, and durations. They are not intended to contain resume text, memory content, prompts, or credentials.
