I provided Full Stack Developer and AI Integration expertise to build a scalable, multi-tenant Event Management and Ticketing SaaS platform with web and mobile applications. Using Node.js, Nest.js, React, TypeScript, and Python with FastAPI, I developed RESTful APIs, real-time dashboards, and secure QR-based check-in systems. I integrated payment gateways, multi-currency processing, and automated workflows. The system was deployed on AWS with scalable infrastructure, optimized for high-traffic events, automation, and secure user management.
