What I'm looking for

I’m looking for a mobile and web development role where I can deliver intuitive Android/iOS/web experiences, own CI/CD and automated testing, and collaborate on UX/UI while building cloud-backed, API-driven features.

I am a mobile and web developer with three years of proven expertise in creating intuitive and efficient interfaces for Android, iOS, and web applications. I’m proficient in Flutter and React Native, and I use Agile methodologies to ensure my solutions meet user needs.

I’ve developed 21 mobile and web applications across key sectors, increasing user engagement by 30% through targeted UX/UI improvements. I also reduced project timelines by 20% by optimizing more agile processes, while achieving a client satisfaction rate of 96% across more than 26 mobile and web projects.

I design and build mobile applications deployed on Google Play and the App Store, incorporating automated testing practices and CI/CD for fast and reliable delivery. I handle versioning, CI/CD, testers and testing environments, and I focus on maintainable software architecture (MVC, MVVM, microservices, SOA).

I’m hands-on with cloud and API-driven development—designing and utilizing REST and GraphQL APIs, managing serverless infrastructure, and supporting offline/online data synchronization. In my end-of-study work, I built an autonomous smartphone geolocation system designed to operate independently of telecom infrastructure, even without SIM cards, IMEI numbers, or third-party services like Google Maps.
