Events shouldn’t stop at buying a ticket 🎟️ They should feel social, interactive, and alive. That’s why I built a social-first event platform where people can do more than just attend events—they can connect, chat, and be part of a community 👥✨ Users can discover events, book and download tickets, follow people they care about, and join real conversations through event chats, group chats, and one-to-one messaging 💬 It’s not just about showing up—it’s about engaging before, during, and after the event 🔄 For organizers, the platform makes it easy to create events, manage ticket tiers, and offer subscription-based access, while staying connected with their audience in real time 📊🎫 The goal was simple: bring social interaction 🤝, ticketing 🎟️, and live engagement ⚡ into one seamless, scalable experience.

AI Agent Development | Business Automation I build AI agents that automate real business workflows and reduce manual effort. These agents act as intelligent digital assistants—handling repetitive tasks, processing information, and taking actions automatically so teams can focus on higher-value work. My approach is focused on practical AI, not experimentation. Every solution is designed to be reliable, secure, and ready for real-world use, helping businesses improve efficiency, speed up operations, and scale with confidence. If you’re looking to use AI to work smarter, cut operational overhead, and streamline processes, I help turn that vision into a production-ready solution.
