Client Background
A rapidly growing lifestyle and fashion retail brand based in Dhaka with 6 physical outlets and a heavily trafficked online catalog. With over 15,000 SKUs and seasonal traffic spikes during Eid and seasonal clearance events, digital sales accounted for over 45% of total company revenue.
The Challenge
The brand was originally running on a bloated, unoptimized WooCommerce setup hosted on a low-tier shared hosting server:
- Frequent Checkout Crashes: During high-intensity social media campaign drops, concurrent user spikes crashed the database, resulting in a 70% cart abandonment rate.
- Painfully Slow Load Times: Average page load exceeded 4.2 seconds on mobile 4G networks, causing high bounce rates among smartphone shoppers.
- Payment Gateway Drops: The legacy bKash and Nagad integration lacked resilient webhook handling, leading to orphaned orders where customers were debited but orders never generated in the warehouse.
- Security Vulnerabilities: Multiple out-of-date third-party plugins exposed the admin panel to brute-force vulnerability vectors.
Our Solution & Technical Strategy
TheWebSolve architected and executed a clean-slate modern e-commerce rebuild tailored specifically to the regional infrastructure constraints of Bangladesh shoppers:
1. High-Performance Headless Core
Instead of another generic monolithic CMS with heavy plugins, we engineered a dedicated Laravel API backend with a responsive Vue.js frontend. Product queries are cached in an in-memory Redis layer with automated cache invalidation upon inventory updates.
2. Resilient Dual-Phase Payment Gateway
We engineered an enterprise-grade payment orchestration micro-service integrating bKash Tokenized Checkout, Nagad Direct Pay, and international SSLCommerz card gateways. Every transaction uses asynchronous webhook reconciliation with idempotent idempotency keys to completely eliminate orphaned charges.
3. Penetration-Tested Hardening
Our founder personally conducted grey-box penetration testing on the staging build, hardening JWT session storage, implementing Cloudflare Turnstile bot deterrence, and locking the inventory backend behind IP-restricted zero-trust access.
Results & Business Impact
- Load time dropped from 4.2s to 1.1s, achieving a Google PageSpeed mobile score of 96.
- Checkout conversion increased by +33% within 45 days of launch.
- Handled 25,000 concurrent active sessions during the Eid Flash Sale with zero server latency degradations.
- 100% elimination of payment webhook drops and inventory sync errors.
During our annual Eid campaign, our legacy infrastructure always crashed and cost us hundreds of orders. TheWebSolve engineered our platform from scratch. Not only did it survive 25,000 live visitors without a hiccup, but checkout conversion went up by a third.
