Software Craftsman
I'm Ryu, Software Craftsman and founder of ALTO. I love building well-crafted software and turning ideas into real products — a maker at heart. I've worked on geomarketing, fintech and e-commerce projects, such as the EVA and Diin platforms, bringing strategy, design and technology together for companies that want to grow on solid ground.

Software Craftsman
More than software that works
Craftsmanship means treating code as a craft: care for every detail, continuous learning and ownership of what goes to production. These are the four values of the Manifesto for Software Craftsmanship that guide my work.
02
Not only responding to change,
but also steadily adding value
03
Not only individuals and interactions,
but also a community of professionals
04
Not only customer collaboration,
but also productive partnerships
