💯 Your Satisfaction, My Commitment — A Full Refund if I Don't Deliver. Certified Developer | 4+ Years Experience | B.Tech in Computer Science | Upwork Certified | 100% Client Satisfaction Hello! I’m Shiv a dedicated Cross-Platform App Developer and UI/UX Specialist focused on building intuitive, high-performance applications that delight users and drive business growth. I specialize in turning complex ideas into smooth, elegant user experiences on any device. I leverage the best of modern development—from the rapid deployment of Flutter to the deep native integration of React Native—to deliver scalable mobile and web solutions. Whether you need a sophisticated e-commerce app, an internal management system, or an engaging SaaS platform, I build it to be fast, beautiful, and maintainable. Here’s how I can help: Custom Mobile App Development: I build beautiful, natively compiled apps for iOS and Android from a single codebase using Flutter. Need to tap into native features? I also utilize React Native to ensure seamless performance and access to device hardware. Scalable Web Solutions: I design and develop robust, user-friendly web applications and dashboards using modern JavaScript frameworks like React and Vue.js, backed by efficient APIs built with Node.js (Express). Product Design & UI/UX: I don't just write code; I design experiences. I focus on creating a crystal-clear user interface (UI) and a smooth user experience (UX) to boost engagement, reduce friction, and keep your users coming back. API Integration & Back-End: I seamlessly connect your app to various services, payment gateways, and databases using RESTful APIs and modern GraphQL. I ensure your app's back-end is secure, fast, and ready to scale. My Toolbox Includes: Mobile Frameworks: Flutter, React Native, Swift (basics), Kotlin (basics) Web & Front-End: React, Vue.js, TypeScript, HTML/CSS, Redux/Vuex Back-End & Databases: Node.js (Express), SQL (PostgreSQL, MySQL), MongoDB Design & Tools: Figma, Adobe XD, Git, Docker, Jest/Mocha (Testing) Languages: Dart, JavaScript (ES6+) I love collaborating with startup founders and product managers who need a technical partner to bring their vision to the App Store and the web with speed and quality.
