About

I am a BSc (Hons) Electronics and Computer Science undergraduate at the University of Kelaniya with hands-on experience in AI/ML, full-stack software engineering, backend development, and cloud deployment. I enjoy solving real business problems by designing, developing, and deploying practical software and AI-powered systems rather than focusing only on academic projects. I have worked on multiple real-world client solutions, including an AI-powered dog-care communication automation platform for a London-based business, a B2B hotel bidding and procurement platform, a COD order tracking and business analytics system, and tourism management applications. My experience covers requirement analysis, system architecture, API development, database design, frontend development, deployment, CI/CD, and production troubleshooting. My AI experience includes NLP, transformer fine-tuning, RAG, agentic workflows, LangGraph, LangChain, vector databases, and LLM integration. My undergraduate research focuses on Sinhala offensive-language detection and context-aware neutral text regeneration using XLM-RoBERTa and mT5 with a custom 30,000-pair dataset. I have also built AI booking agents and 24/7 customer-support and receptionist systems using FastAPI, n8n, Pinecone, Qdrant, Gemini, and Hugging Face technologies. For cloud and DevOps, I have worked with Docker, Kubernetes/EKS, Terraform, GitHub Actions, AWS, Google Cloud, Azure, Oracle Cloud, Linux, and Nginx. Alongside my studies, I founded Codinfrinex and have gained practical experience delivering software solutions for real clients. I am currently seeking an internship where I can contribute as an AI/ML, Software, Backend, or Cloud Engineer while continuing to strengthen my engineering skills.
