What I'm looking for

I seek a senior mobile role where I can lead cross-platform development, improve app performance, implement CI/CD and security best practices, mentor teams, and deliver measurable business impact in a collaborative, product-focused environment.

I am a Senior Mobile App Developer with 8+ years delivering iOS, Android, and cross-platform solutions using Swift, Kotlin, Flutter, and React Native. I lead teams, own roadmap execution, and drive performance improvements via profiling, offline caching, and dependency audits that reduced crash rates and improved time-to-interactive.

I have implemented CI/CD pipelines (Jenkins, Fastlane), mobile security best practices, and payment gateways, yielding faster releases and improved transaction success. I architect scalable cloud integrations (Firebase/AWS), set up analytics and A/B experiments, and migrated native apps to cross-platform stacks to reduce cycle time and increase retention.

I prioritize accessibility (WCAG 2.1 AA), testing (XCTest, JUnit), code review standards, and documentation. My work includes shipping high-impact products, mentoring teammates, and maintaining strong collaboration across product and engineering to align features with business goals.
