What I'm looking for

I am looking for a role that offers opportunities for technical leadership, innovation, and collaboration in mobile security and application development.

I am a high-performing Staff Android Engineer with over 13 years of experience in native Android development, specializing in Kotlin and Java. My career has been marked by a commitment to delivering high-impact work and fostering strong internal and external relationships to achieve collaborative goals. I thrive in fast-paced environments and leverage my skills in mobile security, performance optimization, and scalable application engineering to drive team success.

Throughout my career, I have developed a comprehensive understanding of the full software development lifecycle (SDLC), including system architecture methodologies such as Clean Architecture, MVVM, MVP, and MVI. My dedication to lifelong learning and continuous improvement has enabled me to implement innovative solutions, such as AI-driven product security enhancements and end-to-end encryption for mobile applications. I am passionate about mentoring others and contributing to the growth of my team through code reviews and technical leadership.
