Full Stack Mobile Developer at IT Youb Consulting who developed a cross-platform fitness app for Android and iOS.

At IT Youb Consulting, I developed a cross-platform fitness application for Android and iOS. I built its mobile frontend with Kotlin Multiplatform and MVVM, and implemented a NestJS backend.

I also developed and maintained a fitness tracking application using Flutter, integrating Firebase services for authentication, storage, and Firestore. I used GetX for state management, navigation, and dependency injection.

As a DevOps Intern at XtendPlex, I implemented CI/CD pipelines for web applications and AI models, and worked on database migration pipelines. I also contributed to centralizing logs and metrics using Scaleway Cockpit and Grafana Cloud.
