Hi, I'm Michael 👋🏻

Michael's headshot

I'm a Flutter Developer with 6+ years of experience building and deploying production mobile and web applications. I specialize in adaptive layouts, app flavors, theming systems, and CI/CD pipelines. I focus on writing maintainable code with clear documentation.

I'm currently working as a Mobile Developer at Upiria, where I'm the sole Flutter developer of a customer-facing tour booking app deployed across Web, Android, and iOS platforms. This involves implementing Figma designs as adaptive Flutter UIs and building custom Navigator 2.0 solutions for web deep linking.

I also work as a Consulting Flutter Developer and Technical Writer, leading technical interviews, developing applications for various clients, and creating technical documentation that greatly reduces developer onboarding time.
