Architect high-security Web3 decentralized applications with Ethers.js, Wagmi, Next.js, and smart contract integrations for startups across Hong Kong Cyberport & Central.
Why Traditional Builds Stall Growth in Hong Kong
dApp interfaces frequently suffer from sluggish wallet connection flows, unhandled RPC rate limits, and clunky transaction states that cause user churn in Hong Kong.
Code-Level Precision & Verified High Performance
I architect production Web3 frontends utilizing Next.js 16, Wagmi v2, Viem, and AppKit with optimistic transaction states, multi-RPC failover providers, and sub-second indexed data querying via Subgraphs.
