Mercedes Franchesca Gonzalez Cejas

Software Engineer specialized in Flutter and mobile development.

I build production-ready mobile experiences with clean architecture, reliable delivery practices, and a strong product mindset.

About

I care about mobile products that stay maintainable while teams keep moving.

I’m a Software Engineer specialized in Flutter and mobile development, with hands-on experience shipping production apps and contributing across UI, business logic, REST API integration, testing, and QA validation. My background combines mobile delivery, clean architecture, and practical product thinking while I keep growing across Android/Kotlin, iOS/Swift, and full-stack foundations through projects like InkScroller.
