Developed an AI-powered content platform that helps marketing teams generate high-quality blog posts, social media captions, Google Ads copy, email sequences, and product descriptions using OpenAI GPT-4 and Claude APIs. The platform features customizable content templates, brand voice training (fine-tuned on client content), content history with version control, team workspaces with role-based access, and a content calendar with scheduled publishing to WordPress and social media APIs. Billing is usage-based through Stripe metered billing — users purchase credit packs that get consumed per generation. The platform serves 2,000+ active subscribers processing 100,000+ generations monthly.
Managing API costs with usage-based billing while preventing abuse, handling streaming AI responses for real-time content preview, and implementing a fair credit system across different content types.
Built a token-based credit system with Redis for real-time usage tracking, implemented Server-Sent Events (SSE) for streaming AI responses to the UI, used tiered rate limiting per subscription plan, and created a cost-estimation engine that maps content type/length to credit consumption before generation.
