What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can leverage my mobile development expertise to create impactful applications while continuing to grow in a supportive environment.

I am a Lead Mobile Developer with over 8 years of experience architecting, building, and scaling high-performance applications for both iOS and Android. My expertise lies in Swift, Objective-C, Kotlin, Java, Flutter, and React Native, and I have a proven track record of driving user engagement by over 30% while optimizing performance and reducing launch time by 40%. I am passionate about clean code and CI/CD automation, and I actively contribute to open-source mobile libraries.

In my current role at Hyperlink, I spearhead end-to-end mobile development for flagship apps, achieving significant improvements in daily active users through innovative features and UX refinements. I mentor a team of developers, conducting code reviews and workshops, and I have successfully implemented CI/CD practices that have reduced release cycle times from bi-weekly to daily. My collaborative approach with UX/UI designers ensures that complex requirements are translated into intuitive user experiences.
