Jason Leonard

Software & Web Developer

I build practical software for real operations—from business management systems to data tools and responsive web applications.

About

I’m an Indonesian ICT graduate based in Melbourne, specialising in Software Technology. I learn best by building things myself—starting with an idea or a real problem, then working through each part until it becomes something useful.

I prefer software that stays practical and understandable. That means clear workflows, dependable behaviour, and solutions that make sense to the people using them. This approach has shaped everything from a commissioned electric-bike showroom to desktop business software and serverless data tools.

Outside conventional software projects, I’ve spent years creating game mods and digital railway content. Working within existing game systems taught me patience, visual attention, and how to improve something through repeated testing—skills that still influence how I design and build software today.
