I build mobile applications, web platforms, AI-powered products, and complete software solutions. From developing an application from scratch to engineering complex features, backend systems, and third-party integrations, I can take your product from requirements to deployment. I'm a Software Engineer working across mobile, web, AI, and backend technologies. My development experience includes Flutter, Dart, Swift, Kotlin, Java, React, Next.js, Node.js, Firebase, AWS, and API integrations. MOBILE APP DEVELOPMENT I develop cross-platform and native mobile applications for iOS and Android. - Flutter and Dart application development - Native iOS development using Swift - Native Android development using Kotlin and Java - Cross-platform application architecture - Mobile UI implementation and performance optimization - Push notifications, background services, and audio and video functionality - Platform channels and native SDK integrations - App Store and Google Play deployment WEB & FULL-STACK DEVELOPMENT I build responsive web applications and backend systems. - React.js and Next.js development - Frontend and web application development - Node.js backend development - REST API development and integration - Authentication and database architecture - Third-party services and payment integrations - Real-time application functionality AI & GENERATIVE AI DEVELOPMENT I integrate AI capabilities into applications and software products. - OpenAI API and LLM integrations - AI-powered mobile and web applications - AI chatbots and conversational interfaces - AI assistants and automated workflows - Retrieval-Augmented Generation (RAG) integrations - Speech-to-text and voice-enabled application features - Integration of AI services into existing products BACKEND, CLOUD & SYSTEM INTEGRATIONS I also work on the infrastructure and integrations that power modern applications. - Firebase Authentication, Firestore, Storage and Cloud Functions - Node.js backend services - AWS Lambda and serverless functions - REST APIs and third-party integrations - Cloud scheduling and background processing - Real-time data synchronization - Native SDK and device integrations - IoT and connected-device functionality PRODUCTION PROJECT EXPERIENCE One of my key projects is Bayaan, a production mobile application developed using Flutter. The project involves Firebase, AWS Lambda, cloud scheduling, audio playback, Google Cast, Alexa integrations, and native Android/iOS functionality. This work has involved building interconnected application features, integrating cloud services, handling platform-specific requirements, and implementing functionality beyond standard mobile UI development. HOW I CAN HELP Whether you need a new mobile application, a native iOS or Android developer, a web platform, an AI-powered product, backend development, or improvements to an existing application, I can help with the engineering and implementation. I focus on understanding the requirements, selecting the right technical approach, building maintainable software, and delivering functionality that works reliably in real-world use. Let's discuss your project, its requirements, and what needs to be built.
