Client Profile
Retail Enterprise
The Business Problem
Their legacy catalog management system had slow updates, causing cart abandonments, pricing discrepancies, and negative feedback from sellers.
Research & Planning
We audited vendor listing loops and verified that database locking during massive concurrent stock updates was the core bottleneck.
We planned a hybrid static/dynamic Next.js site powered by a NestJS API cluster, with Redis handling fast inventory buffers.
Design & Architecture
Created clean, light dashboard interfaces focusing on rapid product additions and simplified inventory checklists.
A Next.js server component layout connected to PostgreSQL with Stripe Connect handling payouts.
Implementation & Testing
The platform was built in 12 weeks. We wrote custom product synchronization scripts and set up stripe payment split webhooks.
Conducted concurrent load tests simulating 10,000 active checkout queries and database sync requests.
Deployment & Outcomes
Deployed using AWS ECS with rolling updates and Vercel for the Next.js frontend catalog.
Created a fast marketplace with 1.1s checkouts, allowing 250+ suppliers to sync inventory.
Key Outcomes
- Average checkout speed reduced to 1.1 seconds
- Supplier onboarding process cut from 5 days to 15 minutes
- Cart abandonment rates dropped by 34%
Lessons Learned
Ensuring database transactions are short prevented system locking during bulk stock imports.
Teebot transformed our multi-vendor platform. The speed of the new site has completely solved our cart dropout issues.
