Ecommerce App

Apex Retail is a rapidly growing multi-brand direct-to-consumer enterprise with over 150,000 monthly active shoppers. Their legacy Shopify storefront was suffering from severe conversion drop-offs on mobile web due to sluggish page load times, complex checkout flows, and zero native personalization.

Workbitz AI architected a unified omnichannel mobile application built on Flutter and Node.js microservices. The platform features an intelligent dynamic product recommendation engine, 1-click checkout with UPI and Apple Pay, and sub-100ms offline product catalog browsing.

Prior to partnering with Workbitz AI, the client operated on a legacy infrastructure constrained by unindexed relational queries, lack of real-time event broadcasting, and brittle monolithic codebases. As transaction volume grew, synchronous API calls routinely triggered blocking cascades, degrading end-user latency and causing operational paralysis during peak traffic spikes.

Furthermore, administrative operations were hamstrung by manual spreadsheet reconciliation and unsegmented data access patterns. Without automated cryptographic backups, role-based access control (RBAC), and standardized API contracts, scaling the platform was technically prohibitive.

We engineered a decoupled headless e-commerce architecture. The mobile app was built with Flutter using state management via BLoC and local SQLite caching for instant offline browsing. On the backend, Node.js and Redis distributed locks (Redlock) ensure zero inventory overselling during peak flash sale spikes.

Payment gateways (Razorpay, Stripe, Cashfree, UPI Intent) were integrated with automated webhook reconciliation fallbacks to ensure 100% payment verification accuracy even in flaky network environments.

The production rollout occurred seamlessly following extensive automated stress tests. The newly deployed platform achieved immediate stability, processing all incoming transactions with a 99.9% uptime record and near-instant sub-second response times.
