Senior Android Engineer

Printec Group

I entered the Fintech filed by joining the core team that builds the framework which holds the base for all major products. The perspective of the code is completely different as there is no room for mistake in the backbone of all mobile products. Even though security and app stability are a must, I was pleased to see that the team was already keeping an eye on Android latest tech stack and some of them were already used. I am excited to work on products that exceed the mobile phones universe and I embrace the challenge of building flexible and robust applications while maintaining stability and security at maximum level.

I joined Zitec for a fresh new project in the medical field. We created the project from scratch and determined every technical aspect of the project (architecture, coding principles and standards, libraries, project structure, design patterns, etc.). It is a challenge in the the forever changing mobile development field to come up with the right approach based on the project type, client needs and timeline.

We opted for a modern tech stack including Jetpack Compose, Material3, MVVM+, Clean Architecture, Retrofit, Moshi, Hilt, Coroutines, Flows, Room etc.

Android Developer

Avira Romania

I was being attracted to the development part wanting to know everything about the android framework. So i took development courses and asked for the change to the development side. I started by writing unit tests for some current features and slowly the difficulty of the tasks has increased. I worked on redesigning different features and creating others. I love the fact that I was able to experiment with different technologies from the early stages such as Coroutines, LiveData, different types of layouts etc. The main programming language was Kotlin.

I have contributed on several projects such as:

  • Avira Antivirus 2021 -> different features redesign or creation using the MVVM architectural pattern and i have used LiveData, Coroutines, Room, OkHttp, ViewModel, Material Design Components etc.
  • Avira Home Guard -> worked in the device discovery, networking protocols implementation
  • SafeThings -> worked on the communication between the application and the router

When opportunity presented itself i joined Avira's Mobile Unit as Mobile QA Automation Engineer. I switched from Appium and Java to Espresso and Kotlin which was great. Hard at first but great.

I have worked with top notch technologies such as Docker for scalability and mobility.

I enjoyed being closer to the full process of creating one of the greatest security application in the world.
