## Projects

- [AI-Powered Support Automation Platform](https://cnayanajith.com/projects/ai-powered-support-automation-platform/case-study): AstraFlow is an AI-powered support automation platform built for a web hosting company facing high ticket volumes and slow response times. The system automatically analyzes and replies to support tickets, manages multi-turn conversations, and escalates complex issues to human agents with clear AI-generated summaries. Integrated Slack, email, and CRM updates ensure seamless handoff. The solution reduced human-handled tickets by 55%, improved response speed, and enabled scalable, efficient customer support operations.
- [DG Upali & Sons (Pvt) Ltd - Corporate Website Design](https://cnayanajith.com/projects/dg-upali-sons-pvt-ltd-corporate-website-design/case-study): DG Upali & Sons (Pvt) Ltd is a logistics and cargo handling company that previously had no website to showcase its services or experience. I designed and developed a professional corporate website that clearly presents their offerings, company background, and completed projects. The new site improves how the business is represented online, makes it easier for customers to understand services, and increases engagement through a clean structure, modern design, and clear calls to action.
- [Neeroga Healthcare - Unified Hospital Management System](https://cnayanajith.com/projects/neeroga-healthcare-unified-hospital-management-system/case-study): Neeroga Healthcare is a multi-specialty medical facility that struggled with fragmented paper-based records and manual scheduling. I developed a high-performance Next.js ecosystem that digitizes the entire patient journey—from AI-powered appointment booking to automated billing and Electronic Medical Records (EMR). The system streamlines clinical workflows, reduces patient wait times, and provides doctors with real-time access to critical health data through a minimal, high-contrast dashboard.
