Motivation
Many users have long appreciated the benefits of online stores, which save time by eliminating trips to shopping centers. Customers can browse products at their own pace, review detailed descriptions, compare prices, and make informed choices. Online stores also help businesses enhance service quality, increase customer loyalty, and provide round-the-clock access to products. The client hired Azati to create a custom store from scratch, including all essential functionality, from direct online payments to order tracking, and later requested integration with a popular payment gateway.
Main challenges
Challenge 01
GDPR Compliance
The team needed to implement full personal data protection under GDPR, including encryption, secure storage, and compliance with processing standards. Azati addressed this by designing GDPR-ready database structures, encryption protocols, and data access controls.
#1
Challenge 02
Lack of Front-End Designs
Without access to UI mockups, backend endpoints had to be adjusted multiple times to match expected front-end behavior. The team worked closely with the client to iteratively test and align API responses with the interface requirements.
#2
Challenge 03
Custom Development vs Existing Solutions
Off-the-shelf solutions couldn’t accommodate the client’s unique workflows and features, necessitating development from scratch. Azati designed a tailored architecture to integrate order management, product recommendations, and payment processing efficiently.

Our approach
Agile Methodology
The project followed SCRUM methodology with Jira for task management. The team coordinated feature development, ERP/CRM integrations, and account management to ensure timely delivery.
Custom E-Commerce Features Development
Our team built custom features like order management, invoice generation, and payment gateway integration to match the customer’s specific business needs. This included multi-language support (German/English) and GDPR-compliant data security.
Payment Gateway Integration
We integrated the payment gateway, supporting PayPal, Visa, Mastercard, and American Express, allowing users to securely complete transactions online.
Performance & Security Optimization
Backend performance was optimized to handle high user traffic, and encryption standards were applied for user data, ensuring both speed and security.
Iterative Testing and Deployment
Each feature underwent testing before deployment to production, with continuous monitoring for performance, functionality, and security compliance.
