System Architecture

Four-tier AI-enhanced enterprise architecture designed for scalability, security, and intelligent automation

Four-Tier AI Architecture (v2.0.0)

🖥️

Frontend Layer

Next.js 14 with App Router and React Server Components

•Pages in src/app/ with RSC
•API routes in src/app/api/
•WebSocket real-time updates
•TailwindCSS utility classes

🧠

AI Services Layer

Hybrid AI combining computer vision with generative AI

•DynamicElementDetector (TensorFlow.js)
•AdaptiveSelectorAI (LLM)
•DataNormalizerAI (LLM)
•GPT-4, Gemini, DeepSeek, Local LLMs

⚙️

Backend Core

Orchestration, security, and data processing

•RPAEngine (orchestrator)
•CredentialVault (AES-256-GCM)
•ETL Pipeline (AI-enhanced)
•WebAutomation (AI-assisted)

🔄

Worker Layer

Background job processing and scheduling

•Extraction worker (BullMQ)
•Scheduler worker (cron)
•WebSocket server (real-time)
•Redis queue management

Data Flow Architecture

1️⃣

User Request (Frontend)

User initiates action via React components → Next.js API routes

2️⃣

Backend Core Services

RPAEngine processes request → CredentialVault retrieves credentials → Queue job

3️⃣

Queue System (BullMQ + Redis)

Job queued with priority and retry logic → Distributed across workers

4️⃣

Worker Processes

Extraction worker executes → Connects to banking networks → Extracts data

5️⃣

Banking Network Sources

Payment processors (Visa, Mastercard, PayPal, Stripe) • Direct bank access (web automation, email/SMS download, manual OCR) • Shared infrastructure (FIS Global, Fiserv - Professional+ tiers)

6️⃣

ETL Pipeline

Validate data quality → Transform to standard format → Load to storage

7️⃣

Data Storage

PostgreSQL (transactional) → Microsoft Dynamic SL (storage or archives) or Microsoft Dynamics 365 (in future)

8️⃣

WebSocket Real-time Updates

Progress events broadcast → Frontend receives updates → UI automatically refreshes

Core Components

⚡RPAEngine

Central orchestration engine for job scheduling and management

const engine = new RPAEngine();
await engine.scheduleJob(config);
await engine.extractData(params);

🔐CredentialVault

Encrypted credential storage with AES-256-GCM encryption

const vault = new CredentialVault();
await vault.store(id, data, options);
await vault.retrieve(id);

🔄ETLPipeline

Extract, transform, load pipeline for data processing

const pipeline = new ETLPipeline();
const result = await pipeline.process(data);
// validate → transform → load

🤖WebAutomation

Headless browser automation with Puppeteer/Playwright

const automation = new WebAutomation();
await automation.navigate(url);
await automation.fillForm(data);
