Vidunadi Perera

I am a final-year Software Engineering undergraduate with hands-on experience building scalable backend services and AI systems. I focus on backend development, Generative AI, Retrieval-Augmented Generation (RAG) and multi-agent orchestration.

At Kingslake Pvt Ltd I developed AI assistants, implemented RAG with ChromaDB, and designed multi-agent workflows using LangChain and LangGraph, improving customer interaction automation and operational efficiency.

I have built production-oriented services using Python, FastAPI, Docker and AWS, and developed systems integrating OpenAI GPT for conversational features. My projects include an AI mental health assistant integrating validated screening tools and emergency escalation, and a concurrent real-time ticketing system using Angular and Spring Boot.

I prioritize building reliable, ethically-aware AI solutions with attention to scalability, conversational safety, and cultural relevance, and I am eager to contribute to teams working on backend systems, LLM-driven products, and cloud-native architectures.
