About

Senior React Native Engineer with 6+ years architecting and shipping production-grade cross-platform iOS and Android applications across fintech, food delivery, automotive, and healthcare. Proven track record at scale — contributed to a payment gateway processing £6M in transactions within one week of launch, and built an Android native module that drove app adoption from 40% to 85% in a single 12-hour window. Deep expertise in native module development (Swift, Kotlin, Objective-C, Java), payment gateway integrations, JSI and the React Native New Architecture, Redux, and CI/CD pipelines. Actively leverages AI coding tools — GitHub Copilot, Claude, Codex, Cursor — and follows AIDLC principles to accelerate delivery velocity, code quality, and GenAI integration across the full product lifecycle. Alongside React Native development, I have worked extensively with native mobile technologies including Swift, Objective-C, Kotlin, and Java, enabling me to contribute across both application and platform-level challenges while bridging the gap between cross-platform and native ecosystems.Over the years, I have had the opportunity to work with organizations including Intellias, Swiggy, CARS24, and Simform, contributing to payment systems, native modules, mobile infrastructure, deep linking, customer-facing applications, and large-scale product initiatives. Areas of Expertise: ▪️ React Native Development ▪️ Cross-Platform Mobile Development ▪️ iOS & Android Development ▪️ Native Modules & Bridge Development ▪️ TypeScript, JavaScript, Swift, Kotlin, Objective-C & Java ▪️ Payment Systems & Fintech Applications ▪️ REST APIs & GraphQL ▪️ Deep Linking & Mobile Infrastructure ▪️ Mobile Architecture & Technical Solutioning ▪️ Unit Testing & Quality Engineering ▪️ CI/CD & Release Management ▪️ Product Engineering ▪️ Cross-Functional Collaboration I am currently open to opportunities aligned with Senior React Native Engineer, Senior Mobile Engineer, and Mobile Engineering, React Native Developer and React Native Engineer roles where I can contribute to building scalable mobile products while continuing to grow across product engineering, architecture, and platform capabilities. I'm always open to connecting with engineering leaders, recruiters, founders, and fellow technology professionals to exchange ideas, discuss mobile engineering, and explore opportunities across product development and mobile technologies.
