01

Custom .NET E-commerce Application Development

We build fully customized e-commerce applications using .NET—from fashion/apparel stores with size/color variants to B2B portals with contract pricing, from subscription commerce to multi-vendor marketplaces—tailored to your business model and customer journey.

02

E-commerce API & Backend Development

We develop secure and scalable backend systems and APIs to manage products, orders, payments, inventory, customer data and third-party integrations. We specialize in connecting .NET e-commerce platforms with Shopify (REST & GraphQL APIs) and Amazon SP API to enable multi-channel selling, automated order sync, inventory management and centralized fulfillment across marketplaces.

03

E-commerce Migration & Modernization

We migrate existing e-commerce platforms to modern .NET architectures, improving performance, security, and maintainability while preserving business continuity.

Key Features

Enterprise-ready architecture

We design modular, maintainable architectures using clean code principles, domain-driven design and microservices patterns to support complex product catalogs, multi-currency checkout, B2B/B2C workflows and marketplace integrations.

High performance under load

Optimized product search (Elasticsearch, SQL Server Full-Text), aggressive caching (Redis, CDN), async order processing and database query tuning ensure fast page loads and smooth checkouts even during flash sales and peak traffic.

Secure payment and data handling

PCI-DSS compliant payment flows, tokenization via Stripe/PayPal/Authorize.net, encrypted customer data (at rest and in transit), and fraud detection hooks protect transactions and customer trust.

Scalable and future-proof solutions

Cloud-native architecture on Azure/AWS with auto-scaling, containerization (Docker/Kubernetes), CI/CD pipelines and API-first design enable seamless expansion to new channels, regions and business models.
