Senior React Native Developer & Tech Lead with 13+ years of software development experience, specializing in production-grade iOS and Android applications. I build, modernize, and maintain scalable React Native applications—from architecture and native integrations to performance optimization, CI/CD, testing, and App Store/Google Play releases. What I can help you with • React Native application development and modernization • iOS & Android development and native module integration • React Native architecture and scalable codebases • Performance optimization and complex bug fixing • TypeScript, JavaScript, Redux Toolkit and API integration • Expo, EAS, bare React Native and OTA updates • Firebase, push notifications, analytics and crash reporting • CI/CD, Fastlane and mobile app release automation • Native iOS (Swift/Objective-C) and Android (Kotlin/Java) integration • BLE, IoT, hardware and third-party SDK integrations AI-Powered Development & Automation I also use modern AI coding tools and agentic workflows to make software development faster and more efficient. I work with tools such as Cursor, Windsurf, GitHub Copilot and ChatGPT to automate repetitive engineering tasks, accelerate implementation, debug complex issues, refactor code, generate tests and documentation, and create automated development workflows. My focus is not simply on using AI to generate code, but on integrating AI into practical engineering workflows while maintaining code quality, architecture, security and reliability. Experience I have worked on production applications across domains including electric vehicles, transportation & logistics, healthcare, IoT, marine systems, infotainment and enterprise mobile platforms. I am comfortable taking ownership of an existing codebase, working with product and engineering teams, understanding complex requirements, and delivering maintainable solutions from development through production release. If you need a senior React Native developer who can take ownership of your mobile application—and also bring modern AI-powered development workflows into the process—I'd be happy to discuss your project.
