FiApply - AI Job & Scholarship Application Automation

FiApply automates job and scholarship applications using AI-powered browser automation, intelligent resume tailoring, and essay generation.

🏗️ Architecture

Monorepo Structure:

FiApply/
├── backend/ # Python gRPC microservices
├── frontend/ # React TypeScript PWA
├── proto/ # Protocol Buffer definitions
├── db/ # PostgreSQL database
└── docs/ # Documentation

Services:

API Gateway (50051) - Client-facing gRPC/HTTP endpoint
AI Orchestrator (50052) - Browser automation + AI workflows
RAG Engine (50053) - Vector search + document storage
LLM Manager (50054) - Ollama (local) + OpenRouter (cloud)

Tech Stack:

Backend: Python 3.11+, gRPC, Connect RPC, Playwright, LangChain, LangGraph
Frontend: React 18, TypeScript, Vite, ShadCN UI, Redux Toolkit, Connect-Web
Database: PostgreSQL 17-alpine3.22 with pgvector, pg_trgm, pg_stat_statements
AI: Stagehand (browser automation), Ollama/OpenRouter (LLMs)

🚀 Quick Start (Docker)

Fastest way to run the entire stack:

# Clone and enter repo 
git clone https://github.com/Firelight-Innovations/FiApply.git
cd FiApply
# Complete setup: install + build + start
make quickstart
# Or step by step:
./scripts/setup-env-modular.sh # Set up environment variables
make build-fast # Build with BuildKit (fast!)
make up # Start all services

For active development (hot reload):

make watch
# Edit code → see changes in <5 seconds!

Access the application:

🎨 Frontend: http://localhost:5173
📚 Swagger API Docs: http://localhost:8080
🔧 gRPC Testing UI: http://localhost:8081
💾 PGAdmin: http://localhost:5050

See Docker.md for complete Docker documentation.

⚙️ Local Development Setup

Prerequisites

Python 3.11+
Node.js 18+
Buf CLI - Installation
uv (Python package manager) - Installation

Installation

1. Install Python Dependencies

# Install uv if you haven't already
curl -LsSf https://astral.sh/uv/install.sh | sh
# Create virtual environment and install dependencies
uv venv
source .venv/bin/activate # Windows: .venv\Scripts\activate# Install all dependencies
uv pip install -r requirements.txt -r requirements-dev.txt
# Install Playwright browsers
playwright install chromium

2. Install Frontend Dependencies

cd frontend
npm install
cd ..

3. Generate Proto Code

# Generates Python, TypeScript, and OpenAPI specs
buf generate

This creates:

Python gRPC stubs → backend/generated/
TypeScript types → frontend/src/generated/
OpenAPI specs → docs/openapi/

Proto Organization: Proto files are organized by domain in proto/ with service definitions, messages, and types separated for clarity. See proto/README.md for details.

4. Configure Environment

Quick Setup:

# Run the automated setup script
./scripts/setup-env.sh

Manual Setup:

# Create .env file from template
cp .env.example .env # if it exists

Edit .env with your API keys:

# LLM Provider (Required)
OPENROUTER_API_KEY=sk-or-v1-your-key-here # Get from https://openrouter.ai/keys# Optional: Local LLM with Ollama
DEFAULT_PROVIDER=ollama # Set to use local models
OLLAMA_URL=http://localhost:11434
# Optional: OpenAI for embeddings
OPENAI_API_KEY=sk-your-openai-key-here
# Development settings
BROWSER_HEADLESS=false # See browser during automation
LOG_LEVEL=INFO

📖 For detailed configuration:Environment Setup Guide

🏃 Running Services

Option 1: Docker Compose (Recommended)

# Full stack with hot reload
make watch
# Full stack (all services)
make up
# Minimal dev setup (gateway + frontend + db)
make dev-minimal
# Individual services
make start-gateway
make start-frontend
make start-db
# View logs
make logs # All services
make logs-gateway # Specific service# Stop all
make down

Option 2: Individual Services (Local)

Terminal 1 - LLM Manager:

python -m backend.services.llm_manager.server

Terminal 2 - RAG Engine:

python -m backend.services.rag_engine.server

Terminal 3 - AI Orchestrator:

python -m backend.services.ai_orchestrator.server

Terminal 4 - API Gateway:

python -m backend.api_gateway.server

Terminal 5 - Frontend:

cd frontend
npm run dev
# Runs on http://localhost:5173

🛠️ Development Workflow

Core Make Commands

make help# Show all 40+ available commands
make quickstart # Complete setup: install + build + start
make watch # Enable hot reload (BEST for development!)
make dev-minimal # Minimal dev setup (gateway + frontend + db)
make up # Start all services
make down # Stop all services
make build-fast # Build with parallel + cache (5-10x faster)
make proto # Generate code from proto files
make status # Check service status
make health # Check service health

Individual Service Control

# Start/stop/restart individual services
make start-gateway
make stop-gateway
make restart-gateway
make logs-gateway
# Service groups
make backend-up # All backend services
make ai-dev # AI development services
make rag-dev # RAG development services

Build & Maintenance

make build-fast # Fast parallel build
make rebuild-gateway # Force rebuild specific service
make prune # Clean unused images/volumes
make clean-cache # Clean Docker build cache
make reset # Complete reset

Development Tools

make swagger # Open API documentation
make grpcui # Open gRPC testing UI
make db # Open database browser
make shell-gateway # Shell into service container

Code Generation

After modifying .proto files:

make proto
# or: buf generate

🧪 Testing the Setup

1. Health Check

# Via REST
curl http://localhost:50051/fiapply.gateway.v1.Gateway/HealthCheck \
-H "Content-Type: application/json" \
-d '{}'# Via gRPC UI
make grpcui
# Navigate to http://localhost:8081

2. Frontend

# Visit http://localhost:5173# Should see the health dashboard

3. API Documentation

make swagger
# Opens http://localhost:8080# Try the HealthCheck endpoint

🚢 Deployment

Building for Production

# Build optimized Docker images
