What I'm looking for

I’m looking for a team where I can architect scalable Android/Flutter products, apply clean architecture and Agile delivery, and take ownership of performance and reliability—while collaborating closely with product and design to ship high-impact features.

I’m a results-driven Mobile App Developer specializing in native Android and cross-platform Flutter, with 5+ years of experience delivering enterprise-grade mobile applications. I build scalable, high-performance apps using clean architecture principles, emphasizing SOLID practices and maintainable design.

In my current role as a Senior Software Engineer, I architect and develop Android and Flutter applications, lead cross-functional Agile teams, and translate product requirements into technical specifications. I implement modern development practices like Jetpack Compose, Hilt dependency injection, and reactive programming with RxJava, while mentoring teams through code reviews and best practices.

Previously, I developed cross-platform Flutter and native Android solutions, built mobile backends with Laravel and PHP, and integrated third-party services such as payment gateways, maps, and analytics. I’m especially proud of projects spanning real-time communication, clean water management with NFC and Flutter, secure VPN, and AR learning with ARCore—always focused on performance, reliability, and user experience.
