- →Implemented Redis-based rate limiting with dynamic throttling based on subscription tier
- →Built WebSocket infrastructure for real-time collaborative editing and content generation
DEVELOPMENT PROCESS
We began with extensive user research, interviewing 50+ content creators to understand pain points. The MVP focused on blog post generation, which we launched to 100 beta users. Based on feedback, we expanded to support 12 content types. We implemented A/B testing for prompt engineering, improving output quality by 40%. The platform launched publicly after 6 months of development and iteration.
TECHNOLOGIES & ARCHITECTURE
Built on Next.js 14 with App Router for optimal performance. OpenAI GPT-4 API integration with custom prompt engineering. PostgreSQL for relational data with Prisma ORM. Redis for caching and rate limiting. Stripe for subscription management. Vercel for deployment with edge functions. Tailwind CSS for responsive UI. TypeScript for type safety across the stack.
RESULTS ACHIEVED
10,000+ active subscribers within 8 months of launch
95% user satisfaction rating based on quarterly surveys
$500K+ ARR achieved in first year
Average content generation time reduced to under 3 seconds
60% reduction in API costs through intelligent optimization

SMART ANALYTICS DASHBOARD
Real-time data visualization and predictive analytics for Fortune 500
PROJECT SCOPE
Develop an enterprise-grade analytics platform for a Fortune 500 retail company to process and visualize real-time sales data across 2,000+ locations. The system needed to provide predictive insights for inventory management and identify emerging trends before they impact revenue.
OBJECTIVES
- Process and visualize data from 2,000+ retail locations in real-time
- Implement machine learning models for sales forecasting and inventory optimization
- Create customizable dashboards for different stakeholder groups (executives, regional managers, store managers)
- Ensure 99.9% uptime with enterprise-grade security and compliance
CHALLENGES
- Handling massive data volumes (50M+ transactions daily) with sub-second query performance
- Training accurate ML models with seasonal variations and regional differences
- Integrating with legacy systems while maintaining data integrity
- Meeting strict security requirements including SOC 2 and GDPR compliance
SOLUTIONS IMPLEMENTED
