Lovepreet S.

I build native and cross-platform mobile applications for iOS and Android using Swift, Kotlin, React Native, and Flutter. With over 9 years of experience, I help startups and established businesses launch new products and improve existing applications. My focus is on intuitive user experiences, reliable performance, secure integrations, and maintainable code. I work from initial requirements through development, testing, release, and ongoing support. ✅ 𝐈 𝐂𝐀𝐍 𝐇𝐄𝐋𝐏 𝐘𝐎𝐔 𝐖𝐈𝐓𝐇: ➠ 𝐍𝐞𝐰 𝐚𝐩𝐩 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭: Technical planning, architecture, and interface implementation for minimum viable products and complex business applications. ➠ 𝐀𝐩𝐩 𝐫𝐞𝐬𝐜𝐮𝐞 𝐚𝐧𝐝 𝐦𝐨𝐝𝐞𝐫𝐧𝐢𝐳𝐚𝐭𝐢𝐨𝐧: Reviewing existing code, resolving bugs, refactoring architecture, adding features, and addressing performance issues. ➠ 𝐁𝐚𝐜𝐤𝐞𝐧𝐝 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭: Building business logic, databases, and services that connect your mobile application with external systems. ➠ 𝐎𝐧𝐠𝐨𝐢𝐧𝐠 𝐦𝐚𝐢𝐧𝐭𝐞𝐧𝐚𝐧𝐜𝐞: Dependency updates, framework upgrades, operating system compatibility, and post-launch support. ✅ 𝐌𝐘 𝐌𝐎𝐁𝐈𝐋𝐄 𝐃𝐄𝐕𝐄𝐋𝐎𝐏𝐌𝐄𝐍𝐓 𝐄𝐗𝐏𝐄𝐑𝐓𝐈𝐒𝐄 𝐈𝐍𝐂𝐋𝐔𝐃𝐄𝐒: ➠ 𝐍𝐚𝐭𝐢𝐯𝐞 𝐢𝐎𝐒: Swift, SwiftUI, UIKit, StoreKit, and device integrations. ➠ 𝐍𝐚𝐭𝐢𝐯𝐞 𝐀𝐧𝐝𝐫𝐨𝐢𝐝: Kotlin, Jetpack Compose, Coroutines, and Room. ➠ 𝐑𝐞𝐚𝐜𝐭 𝐍𝐚𝐭𝐢𝐯𝐞: TypeScript, Expo Router, native modules, and the New Architecture. ➠ 𝐅𝐥𝐮𝐭𝐭𝐞𝐫: Dart, reusable interface components, Riverpod, BLoC, and platform channels. I recommend a native or cross-platform approach based on your features, device requirements, budget, and maintenance needs. ✅ 𝐅𝐄𝐀𝐓𝐔𝐑𝐄𝐒 𝐈 𝐁𝐔𝐈𝐋𝐃 𝐈𝐍𝐂𝐋𝐔𝐃𝐄: ◆ User registration, social login, biometric authentication, and role-based access. ◆ Real-time messaging, push notifications, and deep linking. ◆ Payments, subscriptions, and in-app purchases. ◆ Camera and media features, file uploads, maps, and location services. ◆ Bluetooth connectivity and Internet of Things integrations. ◆ Offline storage, background processing, and data synchronization. ◆ Product analytics and usage tracking. ✅ 𝐅𝐎𝐑 𝐁𝐀𝐂𝐊𝐄𝐍𝐃 𝐃𝐄𝐕𝐄𝐋𝐎𝐏𝐌𝐄𝐍𝐓 & 𝐈𝐍𝐓𝐄𝐆𝐑𝐀𝐓𝐈𝐎𝐍𝐒 𝐈 𝐖𝐎𝐑𝐊 𝐖𝐈𝐓𝐇: ➠ 𝐋𝐚𝐧𝐠𝐮𝐚𝐠𝐞𝐬 𝐚𝐧𝐝 𝐟𝐫𝐚𝐦𝐞𝐰𝐨𝐫𝐤𝐬: Node.js, NestJS, Python, and FastAPI. ➠ 𝐏𝐥𝐚𝐭𝐟𝐨𝐫𝐦𝐬 𝐚𝐧𝐝 𝐝𝐚𝐭𝐚: Firebase, Supabase, PostgreSQL, MySQL, MongoDB, and Redis. ➠ 𝐂𝐨𝐦𝐦𝐮𝐧𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐚𝐧𝐝 𝐚𝐜𝐜𝐞𝐬𝐬: REST APIs, GraphQL, WebSockets, OAuth 2.0, and token-based authentication. 𝐈 𝐚𝐥𝐬𝐨 𝐢𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐞 𝐚𝐫𝐭𝐢𝐟𝐢𝐜𝐢𝐚𝐥 𝐢𝐧𝐭𝐞𝐥𝐥𝐢𝐠𝐞𝐧𝐜𝐞 𝐟𝐞𝐚𝐭𝐮𝐫𝐞𝐬 𝐮𝐬𝐢𝐧𝐠 𝐎𝐩𝐞𝐧𝐀𝐈, 𝐀𝐧𝐭𝐡𝐫𝐨𝐩𝐢𝐜 𝐂𝐥𝐚𝐮𝐝𝐞, 𝐚𝐧𝐝 𝐆𝐨𝐨𝐠𝐥𝐞 𝐆𝐞𝐦𝐢𝐧𝐢 𝐭𝐡𝐫𝐨𝐮𝐠𝐡 𝐛𝐚𝐜𝐤𝐞𝐧𝐝 𝐬𝐞𝐫𝐯𝐢𝐜𝐞𝐬: ◆ In-app chat and voice assistants with streaming responses. ◆ Document assistants using retrieval-augmented generation, embeddings, and vector search. ◆ Image understanding, document processing, speech recognition, and content generation. ◆ Semantic search and personalized recommendations. ◆ Agents that interact with external tools and data, including Model Context Protocol integrations when relevant. Each feature starts with a defined user need. I consider data access, response quality, error handling, and operating costs throughout implementation. ✅ 𝐓𝐄𝐒𝐓𝐈𝐍𝐆 𝐀𝐍𝐃 𝐑𝐄𝐋𝐄𝐀𝐒𝐄 𝐒𝐔𝐏𝐏𝐎𝐑𝐓 𝐈𝐍𝐂𝐋𝐔𝐃𝐄𝐒: ◆ Automated checks with Jest, Flutter testing tools, and Maestro, selected for the application. ◆ Real-device testing, TestFlight builds, and Google Play internal testing. ◆ Build and release automation using GitHub Actions and fastlane, with Expo Application Services for React Native projects. ◆ App Store and Google Play submission support. ◆ Crash monitoring with Firebase Crashlytics and Sentry. I use artificial intelligence coding tools to assist with development, debugging, and code analysis. I review and test generated code and remain responsible for architecture, security, and release readiness. You can expect agreed milestones, regular progress updates, and a documented handover. We begin by defining your users, essential features, and launch priorities, then build and validate the application in manageable stages.
