Hi there 👋 I'm Pulina Wickramasooriya

My career path is growing as a Software Engineer and Full Stack Developer specializing in Generative AI and LLM-powered applications. I build production-grade AI systems, including multi-agent pipelines and RAG chatbots and engineer AI-driven solutions for real-world applications.

My foundation in C sharpened my problem-solving instincts. Since then I've grown across Java, Python, JavaScript, and TypeScript, delivering scalable full-stack applications and intelligent agent systems.

I'm passionate about pushing LLMs beyond demos, fine-tuning models, orchestrating agent graphs, and leveraging AI across the full software development lifecycle. Always learning, always building. 🚀
