My development experience included building **AI-powered SaaS applications, full-stack web applications, custom dashboards, APIs, MVPs, and scalable digital products** using **React.js, Node.js, MongoDB, Python, React Native, Flutter, and Firebase**. I also developed **iOS and Android applications**, including cross-platform solutions, API integrations, authentication, real-time features, notifications, payment integrations, and app deployment. Additionally, I worked with **Shopify, WordPress, WooCommerce, Webflow, and Wix** to develop and customize websites and eCommerce solutions. ### Key Experience ✔ Secure Software Development & Information Security ✔ AI & SaaS Application Development ✔ Full-Stack React.js, Node.js, MongoDB & Python ✔ React Native, Flutter, iOS & Android Development ✔ Authentication, API Security & Data Protection ✔ RESTful & GraphQL API Development ✔ AI Integrations & AI-Powered Features ✔ Shopify, WordPress & WooCommerce Development ✔ Webflow, Wix & Figma-to-Web Development ✔ MVPs, Dashboards & Custom Web Applications ✔ Firebase, Stripe & Third-Party Integrations ✔ Real-Time Applications & Messaging ✔ Deployment, Optimization, Maintenance & Bug Fixing
