Top Rated
Project details
I build intelligent AI automation systems, Voice Agentic systems and RAG based chatbots using n8n and modern AI technologies. These systems can integrate with messaging platforms (Telegram, WhatsApp), cloud services (Google Calendar, Gmail, Drive), PDFs, images, audio and other data sources. I design workflows that automate tasks, answer questions from documents, manage calendars, process emails, generate reports and provide voice or chat based responses. My solutions are fully scalable, customizable and tailored to your business, helping you save time, improve productivity and leverage your data efficiently. Whether you want a personal AI assistant, enterprise automation workflows or voice enabled RAG chatbots, I can build it for you.

🎯 WHY WORK WITH ME?
I work across both AI engineering and full-stack software development, allowing me to build more than isolated AI prototypes.
I can work across the complete development lifecycle:
Idea → Architecture → AI/Agent Development → Backend → Frontend → APIs → Database → Automation → Deployment
My focus is on building AI systems that are:
✓ Practical and business-focused
✓ Reliable and maintainable
✓ Designed for real-world workflows
✓ Integrated with your existing tools and APIs
✓ Built with clean and scalable architecture
✓ Ready to evolve as your business grows
I have hands-on experience developing AI automation systems, conversational AI, voice agents, RAG applications, full-stack platforms, machine learning solutions, and production-oriented backend systems.
I am also completing my BSc (Hons) in Computer Engineering at the University of Jaffna, Sri Lanka, with a strong focus on Artificial Intelligence, Machine Learning, and Software Engineering.
💡 HAVE AN AI IDEA?
If you are planning an AI agent, AI automation workflow, RAG assistant, voice AI system, AI SaaS product, or full-stack AI application, send me a message.
I can help you determine the right architecture, technologies, and implementation approach — and turn your idea into a working system.
