Base Ghost v1 – Tradable Pump.fun → Raydium Sniper Bot
Syed has been professional, responsive, and structured throughout our development phase. He communicates clearly, works methodically, and remains adaptable as project requirements evolve. We are temporarily pausing to complete further testing and define the next upgrade scope with greater precision, and I appreciate his patience and cooperation during this stage. I would be happy to collaborate with him again on future phases.

I make sure that does not happen
✅ 10+ years building production iOS and Android apps for fintech, crypto, AI, and Web3 companies
✅ Senior Flutter and React Native developer, cross-platform from architecture to App Store
✅ Top Rated on Upwork with $100K+ earned
✅ Real shipped products with active users on both stores right now
What I built:
✔ Mobile Apps: Flutter (Dart) and React Native (TypeScript) for iOS and Android. Startup MVPs, production rewrites, cross-platform apps, real-time systems, offline-first architecture, App Store and Play Store deployment. No supervision needed, no handholding, no gaps.
✔ Fintech and Crypto: non-custodial crypto wallets, Stripe payment integration, in-app purchases, KYC and KYT flows, trading platforms, multi-chain mobile wallets, fiat to crypto flows, banking app architecture.
✔ AI-Powered Mobile Apps: OpenAI API and Claude API integrations, LangChain workflows, RAG pipelines, AI chatbots, conversational interfaces, AI agents, on-device inference, LLM-driven automation built directly into mobile products.
✔ Blockchain and Web3: Ethereum, Solana, XRP Ledger, Bitcoin. Solidity and Rust smart contracts, DeFi protocols, NFT marketplaces, DAO governance, RWA tokenization, WalletConnect, MetaMask, multi-sig flows, dApp frontends.
✔ Backend and Infrastructure: Node.js, NestJS, REST APIs, GraphQL, WebSockets, Firebase, MongoDB, PostgreSQL, AWS, Docker, CI/CD pipelines. I own the backend, too, so you do not need a separate hire.
Most clients come to me because they need one developer who owns the entire product: mobile app, backend, integrations, blockchain layer, and deployment. No coordination overhead. No gaps between layers. One clear line of responsibility.
If you are building a fintech app, crypto wallet, AI-powered mobile product, or Web3 platform, send me your project details. I will respond with a clear technical plan and honest timeline within a few hours.
