What I'm looking for

I seek a hands-on mobile development role where I can build scalable Android apps, improve UX, collaborate cross-functionally, and grow technically in a dynamic team.

I am a passionate, detail-oriented Android developer with hands-on experience building scalable mobile applications using Java and Kotlin, integrating Firebase and REST APIs, and applying UI/UX principles to deliver polished user experiences. I implemented MVP architecture, debugged and optimized apps with Android Studio, Logcat, and Crashlytics, and contributed a Best Capstone Mobile App candidate project (Emergency Response Tool).

In addition to mobile development, I supported system administration tasks—managing FTP and JumpServer uploads, configuring IIS websites, installing SSL certificates (ZeroSSL, CDN Plus, aaPanel), and performing DNS management with DNS.com and Cloudflare—demonstrating a broad technical skill set and a focus on performance and security.
