Summary
Gen AI & Automations Technology Consultant at EY | Software & AI Engineer at Quickdesk | Bachelor of Computer Science Monash University. 🚀 AI Engineer | Full-Stack Developer | Tech Innovator Hi, I’m Sean — a Software and AI Engineer passionate about building intelligent systems that drive real-world impact. Currently a Technology Consultant at EY, I specialize in leading AI-driven transformations and full-stack development projects. 🔍 From building a high-accuracy facial recognition check-in system for EY events (no more queues!) to pioneering LangChain-based RAG pipelines hosted on SAP AI Core, I’ve been hands-on with the latest in AI engineering. I also developed vector-based data solutions to clean address fields, detect duplicates, and optimize data integrity for enterprise systems. 💬 Before EY, I led the development of personalized GPT-4-powered chatbots at Quickdesk — integrating RASA for consistency, Redis vector stores for memory, and delivering hybrid conversational experiences that balance reliability with innovation. 💡 I’m especially passionate about agentic AI, scalable backend systems, and using vector search to solve business problems. When I’m not building, I mentor teams through EY's AI Challenge (50+ university teams in 2024!) and continue experimenting with LLMs, multithreaded tools, and ML frameworks. 📚 Monash Computer Science grad, hackathon winner, and certified in both SAP Generative AI and EY’s AI Engineering program.
