Greetings 👋,

I’ve built production-ready crypto apps (Flutter) with secure key management, EVM support, and WalletConnect integration. Let’s cut to why I’m a fit:

🔑 Your Needs ⇄ My Expertise

EVM Chains: Integrated Ethereum/BSC/Polygon in Picklezone (Web3dart, 1K+ users).
Security: Biometric auth, encrypted key storage (AES-256 + enclaves), anti-tampering against reverse engineering.
WalletConnect 2.0: Implemented in 2 prior projects (see Picklezone’s TX flow).
Gas Fees & NFTs: Built dynamic fee estimation + ERC-721/1155 viewers (demo available).

🚀 Why Me?
Blockchain Focus: Led Picklezone’s mobile dev (Web3 + in-app TX) – App Store.
Security Cred: Reversed engineered malware for fun – your keys won’t leak on my watch.
Speed: Can start tomorrow. Prefer Flutter (clean architecture, 4 published apps).
Tech Stack I’ll Use:

Flutter (Dart) + Web3dart/ethers.js
WalletConnect 2.0 + Secure Storage (Flutter Secure Store/RSAPackages)
Firebase (Push) + optional Node.js backend

📩 Let’s Discuss:
How to prioritize features (MVP vs. “nice-to-haves”).
My approach to preventing APK/IPA reverse-engineering (obfuscation, runtime checks).
Attached: CV + Picklezone code samples (NDA-safe). Available for a call today.

Best,
Alex Mosisa Expand

1. Which EVM chains must be supported at launch, and will new chains need to be added later?
2. Should the wallet support only one account per device or allow multiple accounts/wallets?
3. Will the app need a backend for analytics, indexing, or managing notifications, or should it be fully client-side?

Hello Ralf

I'm very interested in your project and believe I can deliver exactly what you're looking for. I have solid experience developing secure and high-performance cross-platform mobile wallets. One of my recent projects was a cryptocurrency wallet for WorkQuest, which involved similar features such as wallet creation, EVM chain support, token transfers, transaction history, and WalletConnect integration.

I am proficient in building apps using React Native with TypeScript and working with Web3 libraries like ethers.js. Additionally, I prioritize strong security practices, including biometric authentication and secure key storage.

I'm confident I can provide a clean, scalable, and user-friendly solution that meets your requirements. I would be happy to discuss your project in more detail and propose an efficient roadmap to complete it successfully.

The price mentioned in the proposal is not final. For an accurate estimate, a detailed clarification is required.

I hold a top position in the Python programming language. :)

Looking forward to your reply! Expand
