E-CLARX is a technology and commerce company that ships full-stack software, runs multi-platform e-commerce operations, and delivers SaaS solutions — all from real operational experience.
E-CLARX LLC is a technology and commerce company founded on a simple principle: every product we ship comes from real operational friction — not theory.
From marketplace automation across Amazon, Walmart, eBay, and Shopify, to full-stack SaaS tools deployed in production — we build the software we actually needed and couldn't find.
Our stack is modern, our approach is lean, and our results are measurable. Whether you need a custom web application, e-commerce infrastructure, or a freelance development partner — we move fast and ship things that work.
Full-stack web applications built with React, Node.js, Python, and Flask — deployed and production-ready on Vercel and Railway.
Active storefronts across Amazon, Walmart, and Shopify — with custom automation and tooling built entirely in-house.
Custom web development for businesses — React, Node.js, Python, Flask, Shopify, and WordPress. Clean code, real results.
Proprietary tools for product discovery, automated listing, price monitoring, and arbitrage — battle-tested at scale.
No buzzwords. No slides. This is what's running in production right now across our software and commerce operations.
Problem: Sellers waste hours reformatting product data between Amazon, eBay, and Walmart — each platform demands a unique CSV structure.
Solution: A multi-marketplace product data conversion SaaS. Upload once, export everywhere. Deployed on Vercel and Railway with live database persistence and Redis caching.
Problem: Merchants import reviews from apps and spreadsheets with no way to know how many actually came from their own customers.
Solution: A Shopify app that audits every review against the store's real order history — matching buyer email, product, and purchase timing — and publishes the verified match rate as a storefront trust badge.
