I’m a Senior React Native Engineer with 6 years of experience building scalable, high-performance mobile apps across Android and iOS. I’ve worked extensively in healthcare, delivering HIPAA- and GDPR-compliant applications, and have led architecture, performance optimization, and native integrations in production apps used by 50k+ users.
A big part of my work has been designing and building internal React Native SDKs to standardize features across teams, reduce duplication, and speed up delivery. I enjoy owning complex frontend systems, collaborating closely with product, design, and backend.

FAQ
Do you work on existing React Native apps?
Yes. I can work on both new and existing React Native codebases, including feature additions, improvements, refactoring, and integrations.
Do you build complete apps or only features?
I do both. Small packages are best for limited features or modules, while larger apps are usually handled through custom offers after requirement review.
Do you provide backend development too?
This gig primarily focuses on React Native mobile development. If your project also needs backend integration, I can work with your existing backend or discuss additional scope.
Can you integrate Firebase or third-party APIs?
Yes. I can integrate Firebase, REST APIs, GraphQL, authentication, push notifications, payments, maps, and other common mobile services.
Will I get the source code?
Yes, source code is included unless explicitly stated otherwise in the custom offer.
Should I contact you before ordering?
Yes. Please message me before placing an order so I can review your requirements and suggest the best package.
