At Code Clowns Tech Solution, I own the backend of a high-traffic dating application, building Node.js/Express REST APIs for web and mobile clients. I keep response times low as traffic scales through MySQL indexing, Redis caching, and production query tuning.
At Papaya Coders Pvt Ltd, I scaled a Bangla calendar API to 20K concurrent users and cut backend API latency by 30% through MySQL index redesign and Eloquent query optimization. I also shipped BBPS-compliant bill-payment infrastructure and integrated OpenAI, Gemini, and DeepSeek behind a provider-fallback chain.
