US Fashion Resale Platform Scales to 100K Monthly Transactions
About the Client
US Fashion Resale Startup
New York, USA
50-100 employees
The Challenge
The existing monolithic platform was unable to handle growing user traffic, leading to frequent downtime during peak sales.
Synchronous payment processing created bottlenecks, resulting in failed transactions and lost revenue.
The search engine degraded as the product catalog grew beyond 500K items, causing poor user experience.
Our Approach
Conducted a thorough infrastructure audit identifying key bottlenecks in the existing architecture.
Designed a microservices-based migration plan using the strangler fig pattern for zero-downtime transition.
Implemented feature flags to gradually shift traffic while monitoring performance metrics in real-time.
The Solution
Migrated to containerized services on AWS ECS with auto-scaling for traffic spikes.
Built an event-driven payment pipeline with Stripe webhooks for reliable transaction processing.
Deployed Elasticsearch for sub-second product search across 2M+ items.
Implemented CDN caching and image optimization reducing page load times by 65%.
Results & Impact
"HashDev transformed our platform from a struggling startup tool into an enterprise-grade marketplace. The migration was seamless and the results speak for themselves."
