A little about me

Thoughtful code.
Human experiences.

I’m Jesserine, a mobile application developer building software since 2017.

I design and develop applications with React Native and Xamarin, backed by experience in native Android and iOS development. I enjoy solving practical problems and turning them into experiences people can use with confidence.

Test-driven development is part of how I work: writing automated tests for features and bug fixes, and caring about what happens after an app ships.
