About Lipu

Mobile & Full Stack Developer with several years of experience in developing Flutter, Android Kotlin, and iOS Swift applications, as well as creating web solutions and business tools.

I work on mobile and full-stack projects end-to-end: technical design, development, performance optimization, maintenance, and deployment. I have notably worked on applications related to logistics, real-time tracking, Zebra Android Enterprise scanners, and various internal business tools.

I can support the development of a cross-platform mobile application with Flutter as well as specific needs in native Android, native iOS, or web front-end.

Main technologies: Flutter, Dart, Kotlin, Swift, TypeScript, React, Node.js, PostgreSQL, Firebase, and REST APIs.
