Commerce Engineering
Headless ecommerce platforms built with MedusaJS and Next.js — from D2C storefronts to B2B marketplaces
GenMedha delivers end-to-end commerce engineering services for businesses in India, UAE, UK, and US — combining open-source commerce engines (MedusaJS, WooCommerce) with modern frontend frameworks (Next.js, React) to build owned, scalable, high-converting ecommerce platforms.
What Is Commerce Engineering?
Commerce engineering is the disciplined approach to designing, building, integrating, and operating ecommerce systems that are scalable, performant, conversion-optimized, and owned by you — not locked into a SaaS platform. Unlike template-based storefronts, we engineer open-source commerce engines with sub-300ms edge speeds, modular API control, and custom B2B/D2C checkout workflows.
Architected for Ownership
Open-source engines (MedusaJS, WooCommerce) with full API control, self-hosted PostgreSQL databases, zero revenue-share cuts, and zero vendor lock-in.
Composable Next.js Storefronts
Decoupled SSR/SSG storefronts built with Next.js App Router, Tailwind CSS, and headless CMS integrations (Strapi, Sanity) for rich product storytelling.
Sub-300ms Performance & Edge Caching
Edge-accelerated caching, image optimization, and technical Core Web Vitals engineering (LCP < 2.5s, INP < 200ms) that maximize conversion rates.
Custom Checkout & Conversion Workflows
Multi-step checkout flows, localized regional pricing, custom B2B quote approvals, and unified global/local payment gateways (Razorpay, Stripe, PayPal).
Architectural Data Flow & Infrastructure
How we structure this capability in production — ensuring zero vendor lock-in, data sovereignty, and sub-second execution.
Composable Next.js Commerce Frontend
Dynamic product pages with sub-second edge SSR/SSG, localized currency, responsive design, and instant cart mutations.
Modular Headless Commerce API
Order state machines, promotion engines, inventory reservation, multi-currency tax calculation, and customer group permissions.
Unified Multi-Gateway Payment Router
PCI-DSS compliant checkouts with 3D-Secure, UPI, Apple Pay, multi-currency escrow, and custom B2B net payment terms.
Automated ERP, CRM & 3PL Dispatch
Real-time courier rate comparison, automated AWB generation, ERP/CRM sync (SAP, Oracle, HubSpot), and PIM catalog connectors.
Core Engineering Focus Areas & Deliverables
Every deliverable is backed by comprehensive TypeScript and Python contracts, automated tests, and clear documentation.
