I am a dedicated Android and Flutter Developer with expertise in building and
deploying advanced Android and cross-platform applications. Holding a Bachelor’s degree in Computer
Engineering, I combine strong technical and architectural skills with strategic problem-solving.
My core strengths include Android and Flutter development using Kotlin,
Dart, Jetpack Compose, and Android Jetpack libraries. I have
extensive experience with Clean Architecture, MVVM, Dependency Injection (Hilt/Dagger), asynchronous
programming with Coroutines and Flow, as well as integration of Firebase and RESTful APIs. Over the
course of my five-year professional career, I have published more than five Android applications on
the Google Play Store.
As a Junior Developer at KMenu, I developed a kiosk module with
payment functionality and continuously added new features to enhance the app’s performance and user
experience.
As a Senior Android Developer at PeopleInNet, I developed a Jetpack
Compose application for controlling vehicle features such as seats, displays, lights, and projectors
over a local network using MQTT.
Implemented multiple Jetpack Compose–based clients for AI agents designed to recommend vitamins and
answer health-related questions.
Developed various Android applications as part of outsourcing projects for partner companies,
including Hyundai Mobis and HMC.
I am passionate about advancing software engineering, striving for excellence, performance, and
efficiency in every project.
