Remote

Senior React NativeDeveloper

With nearly 6 years of experience in React Native and React, I specialize in developing scalable, high-performance mobile applications across healthcare, consumer apps, and high-traffic solutions. My expertise includes complex integrations with health platforms, payment systems, custom map routes, and advanced iOS features like Live Activity.

I have built diverse features including AI chatbots, video calling, live GPS tracking, and e-commerce solutions. Working with various APIs and technologies, I successfully manage complete project lifecycles from conception to release.

As a team leader, I focus on collaboration, performance monitoring, and efficient coordination. I can independently manage projects from ground zero to production, ensuring high standards and timely delivery while staying at the forefront of technology.

Available for freelance projects, contract work, and consulting. I work remotely with clients worldwide, delivering professional solutions across all time zones.
