Hi, I'm Simranjeet. I build iOS and Android apps with React Native, with the backend, APIs, and AI features needed to make them work as real products, not just prototypes. Most of the projects I work on fall into one of three categories: a new mobile MVP, an existing app that needs to be improved or extended, or a mobile product that needs AI functionality. I work primarily with React Native, TypeScript, JavaScript, and Expo, and can take care of the product around the app as well, APIs, authentication, databases, notifications, integrations, and web/admin functionality. What I build MOBILE - iOS and Android apps with React Native Cross-platform applications MVPs from an idea or Figma design Existing app improvements and new features App debugging, performance work, and maintenance Push notifications and device integrations App Store and Google Play release preparation BACKEND & INTEGRATIONS - REST APIs and third-party integrations Node.js backends Authentication and user management Firebase and cloud services PostgreSQL and MongoDB Payments, subscriptions, and other product integrations AI INSIDE MOBILE APPS - AI assistants and chat experiences LLM/API integrations AI-powered workflows Connecting AI features to existing mobile products AI MVPs where the mobile experience is the main product For MVPs, I keep the first version focused. A good MVP doesn't need every possible feature. It needs the right user flow, a solid technical foundation, and enough of the product working to put it in front of real users. I can work from Figma designs, product requirements, an existing codebase, or a rough idea and help turn it into a practical first release. MY CORE STACK - React Native · Expo · TypeScript · JavaScript · Node.js · Firebase · REST APIs · PostgreSQL · MongoDB · Git If the project already has a web application or backend, I can work with that too rather than treating the mobile app as a separate system. If you're building a new mobile product, adding features to an existing app, or looking for someone to take an MVP through development, send me what you're building and where you are with it.
