I'm Benny, a software engineer based in Sydney, Australia, with over 10 years of experience building software.
My background covers full-stack development, enterprise systems, software architecture, and technical leadership. I've worked on everything from web and mobile applications to ERP, CRM, and financial systems, and previously led a team of 20+ engineers.
These days, I'm spending more time on AI engineering, particularly LLM orchestration, memory systems, RAG, and building reusable AI infrastructure.
I enjoy understanding how things work, designing practical solutions, and turning ideas into working products.
