At Webapphealing Technology Pvt. Ltd., I engineered a WhatsApp Business API webhook with two-way receivers using Meta Cloud API, reducing missed appointments by 50%.

I delivered a pet clinic management system using the MERN stack that served 1000+ active users and cut manual booking time by 90%. I also built a node-cron scheduling engine for appointment reminders and vaccination expiry alerts.

At ELVYN CHESS, I developed REST APIs for a chess learning management system using Spring Boot and PostgreSQL, and built responsive React components with API integration.

On my projects, I built an AI-powered RAG chatbot platform and an MCP server for Claude AI integration. I also containerized a Node.js app and implemented a GitHub Actions CI/CD pipeline for Azure Container Apps.
