Projects using iOS in RawalpindiProjects using iOS in RawalpindiMost people trying to fix a home appliance are stuck flipping through a PDF manual or guessing which part is causing an issue. OnSense set out to replace that with an app where entering a model number instantly surfaces specs, part breakdowns, and an AI assistant trained specifically on appliance repair knowledge — not a generic chatbot.
What I worked on
As part of the mobile engineering work on the React Native (Expo) app, I built the OCR module that lets users scan an appliance's nameplate with their camera to automatically identify the model and pull it into the system — removing the need to manually type in model numbers that are often worn, tiny, or hard to read.
Stack:
React Native (Expo) for iOS and Android
OCR/camera-based scanning for nameplate recognition
AI chat integration (OnSense GPT) for appliance-specific Q&A
Backend integration with the platform's parts and repair-knowledge database
What's in the app:
Model lookup by number, with detailed specs and part breakdowns
Exploded View module — an interactive, clickable diagram of appliance parts
OnSense GPT chat assistant for error codes, repair steps, and part compatibility
Nameplate scanning via OCR for fast, accurate model identification
Parts cross-referencing against verified compatibility databases I developed TomiPay, a multi-chain crypto wallet and Web3 super app built for users to manage digital assets, send and receive crypto, swap tokens, explore NFTs, connect with dApps, chat with users, use AI features, and send digital gifts.
TomiPay supports major blockchain networks including Bitcoin, Solana, Tron, Ethereum, BSC, Base, Polygon, and Sonic. Users can manage their crypto portfolio, view token balances, send and receive assets, swap tokens, manage NFTs, connect through WalletConnect, and interact with decentralized applications.
Beyond wallet features, I built an AI-powered experience and real-time chat system inside the app. Users can communicate through secure chat, access AI features, and use a complete gift system to send, receive, and manage digital gifts within the platform.
The project included portfolio tracking, QR-based receive flow, wallet address display, copy/share address, token management, NFT wallet functionality, token swaps, WalletConnect integration, dApp connectivity, AI features, chat system, gift shop, gift sending, gift receiving, and complete digital asset management.
This project focused on crypto wallet development, blockchain wallet integration, multi-chain wallet support, Web3 app development, DeFi wallet features, AI-powered Web3 apps, crypto chat apps, NFT wallet functionality, WalletConnect integration, dApp connectivity, token swaps, crypto portfolio tracking, and digital gift systems.
