About

I'm Leo, a full-stack engineer based in the Philippines. I work across frontend, backend, databases and infrastructure, usually on software that supports real business operations.

A lot of my work involves taking manual workflows, understanding how teams actually use them, and turning them into systems that are easier to operate and maintain.

I enjoy debugging difficult problems, improving performance and understanding how the different parts of a system fit together.
