Hi, I'm Andy Marthin Christo
I build
Software Engineer focused on backend services, APIs, and macOS apps.
About Me
Hello! I’m a software developer with a dual passion: crafting robust, scalable back-end systems and building pixel-perfect, native applications. With a strong background in Ruby on Rails, I excel at creating the logic that powers complex web services.
Separately, as a Swift developer, I have a deep appreciation for the Apple ecosystem and user-centric design, which I bring to my macOS app development. I thrive on solving complex problems, whether on a server or a desktop.
What I Do
Back-End Development
Building high-performance, test-driven APIs and web applications using Ruby on Rails and Python.
Native macOS Apps
Developing clean, responsive, and user-friendly desktop applications using Swift and SwiftUI.
