Project description:
"Online Platform & Wine Vending Machine Integration
General Objective

Development of a complete online wine sales platform, fully integrated with vending machines.
The vending machine software will remain basic, while the platform will handle all advanced features: e-commerce, reservations, payments, AI recommendations, multi-channel notifications, invoicing, and accounting integration.

Core Features:
Full e-commerce platform
Detailed wine catalog (warehouse + vending stock).
Customer accounts with invoicing (individuals & companies).
Automatic company data validation (fiscal code check).
Age restriction: sales blocked for users under 18 (age verification / KYC).
Online payments (card, Apple/Google Pay, PayPal).

Vending machine integration:
Real-time bidirectional stock synchronization.
Online reservations with 24h hold + auto-release.
Unique QR codes for pickup (sent via email, SMS, WhatsApp).
Machine display messages: “Reserved / Paid Online – Not Available”.
Remote temperature control & ±1°C alarm monitoring.

AI Wine Recommender:
Dynamic recommendations for food pairing, events, seasons, customer preferences.
Runs on both the website and vending machine touchscreen (interactive).
Always shows 3 recommendations, sorted by price (highest first), filtered by available stock.

Invoicing & Accounting:
Automatic invoices for every order.
Integration with accounting software (e.g., SAGA).

Notifications & Loyalty:
Email, SMS, and WhatsApp notifications (order confirmation, pickup reminder, expiration).
Loyalty points, coupons, promotional campaigns.

Compliance & Security
GDPR compliance, Romanian/EU fiscal rules.
PCI DSS for payment security.
OAuth2/JWT authentication, HMAC for webhooks.
Enterprise-grade scalability & reliability.

Complexity Analysis:
Multi-system Integration: E-commerce + vending + AI + accounting + payments + messaging.
Enterprise-grade Features: invoicing, fiscal validation, 18+ KYC.
Real-time Systems: inventory sync, temperature monitoring, alarm system.
AI/ML: custom recommender engine with learning capabilities.
Compliance: GDPR, fiscal regulations, PCI DSS.

Development Steps:
Testing & QA: unit, integration, end-to-end, pilot with a real machine.
Integration Work: vending API, accounting software, payment processors.
Regulatory Compliance: fiscal, GDPR, KYC.
Security & Performance: OAuth2/JWT, HMAC, rate limiting, enterprise-grade uptime.

Developer Requirements:
Enterprise e-commerce: experience with online payments, invoicing, ERP integrations, PCI DSS.
Hardware/IoT Integration: proven work with connected devices (vending, IoT, smart hardware) via API/WebSocket/MQTT.
AI/ML: recommender systems (ideally in food & beverage or retail).
Accounting/ERP integration: SAGA, SAP, Microsoft Dynamics, or similar.
Multi-channel communications: email, SMS, WhatsApp Business API.
Compliance: GDPR, fiscal regulations, 18+ restrictions.
Security & scalability: OAuth2, JWT, audit trail, enterprise-grade performance.
Bonus: Experience with vending or retail projects; UI/UX for touchscreen/kiosk applications.

Deliverables:
Complete responsive e-commerce platform.
Admin dashboard (stock, machines, ads, reports).
AI recommender engine.
Integration layer with vending machine API.
Documentation (technical + user manuals).
Pilot test with at least one vending machine.

Timeline:
Delivery must be done in the shortest possible time.

Screening Questions for Freelancers:
Have you built enterprise-level e-commerce platforms with online payments and invoicing? Please share examples.
Do you have experience with hardware/IoT integrations (vending machines, connected devices)? Which protocols/APIs have you used (REST, MQTT, WebSocket)?
Have you developed AI/ML recommender systems? Can you share a live example or demo?
Have you integrated with accounting/ERP systems (SAGA, SAP, Dynamics)? How did you handle stock and invoice synchronization?
Have you implemented multi-channel notifications (email, SMS, WhatsApp Business API)? How do you ensure deliverability at scale?
How would you implement GDPR compliance and 18+ verification (KYC) while avoiding sensitive data storage?
What security measures would you apply (PCI DSS, OAuth2, JWT, HMAC, SLA-level uptime)?
What methodology do you use (Agile/Scrum, milestones)? Do you provide regular demos during development?
Based on the requirements, what cost and timeline estimate can you provide?
Can you share portfolio links or references from similar projects (e-commerce + hardware integration + AI)?" (client-provided description)
