Zappy is a mobile first shared WhatsApp inbox for small businesses, designed to turn chaotic customer messaging into structured team workflows.
The core problem is not messaging, but coordination. As small teams grow, conversations become fragmented, messages are missed, and there is no clear ownership or system of work.
I designed Zappy as a real time, multi tenant communication system where every business operates in an isolated workspace, and every conversation is structured, trackable, and assignable across team members.
The system is built with a contract first architecture using OpenAPI and shared types, ensuring the backend and mobile app stay fully in sync as the product scales.
Real time updates are handled through Socket.IO (http://Socket.IO), with fallback polling for reliability across environments.
On top of this communication layer, AI is embedded directly into workflow moments, not as a separate tool. It assists with reply suggestions, conversation summaries, tone rewriting, sentiment detection, and off hours responses, all aimed at reducing cognitive load and response time for small teams.
Zappy is ultimately a workflow layer for WhatsApp based businesses, focused on structure, speed, and clarity in customer communication. Flutter Mobile App Development
Building one high-quality mobile experience for both iOS and Android with Flutter
A great mobile app should feel fast, reliable, and natural regardless of whether a customer uses iOS or Android. With Flutter, I help startups and businesses build polished cross-platform applications from a shared codebase while maintaining a consistent user experience across devices.
My Flutter work can include:
•Turning product ideas and Figma designs into production-ready mobile interfaces
•Building reusable, maintainable UI components
•Connecting apps to REST APIs, authentication systems, payments, and cloud services
•Implementing responsive layouts for different screen sizes
•Improving performance, stability, and release readiness
•Supporting App Store and Google Play deployment.
For this type of project, the goal is not simply to write code. It is to create a dependable product that is easier to maintain, faster to improve, and ready to grow with the business.

#Flutter #FlutterDeveloper #MobileAppDevelopment #iOSDevelopment #AndroidDevelopment #CrossPlatformDevelopment #MVP #AppDevelopment BlockFlow — Native Crypto Wallet App (Android)
Designed a 25-screen Web3 wallet UI, then shipped the native app.
BlockFlow is a connect-only, non-custodial crypto wallet built with Expo and React Native. Users connect MetaMask, Phantom, or 600+ wallets via WalletConnect, funds never leave their wallet.
The app reads live ETH balances (Alchemy) and SOL balances (Helius), with send/receive, transaction history, swap (Jupiter on Solana), NFT gallery, staking links, referral/rewards, analytics, and settings (testnet/mainnet toggle).
This is the full product behind the design system I posted earlier, not just Figma frames or an HTML prototype.
