Oluwafemi's GitHub stats npm npm npm npm npm

👋 Hi, I’m Oluwafemi — On-Chain Builder & Web3 Developer

I’m a blockchain developer passionate about building open, permissionless, and composable tools across multiple chains. My work focuses on creating real, functional on-chain products that solve problems around identity, tokens, payments, and user experience.

🚀 What I Build

I work across several ecosystems including Ethereum, Base, Stacks, Celo, and other EVM chains. My projects typically involve:

  • Dapps with full wallet integration (EVM & non-EVM)
  • Smart contract interactions for tokens, signing, authentication, and tracking
  • On-chain dashboards (contributors dashboards, leaders dashboards, token discovery, charts, analytics)
  • Gas-optimized systems for batch transactions, savings vaults, and automated processes
  • User-focused experiences—clear UI, fast performance, and mobile-friendly design

🔗 Chains I Build On

  • Ethereum — contracts, dapps, tooling
  • Base — L2-native apps, memes, growth dashboards
  • Stacks — Bitcoin-secured apps, STX Vaults, BTC-backed savings
  • Celo — stablecoin and payments tooling
  • Other EVM chains — cross-chain features and integrations

🧠 My Philosophy

I build because I believe on-chain systems should be simple, transparent, and accessible—especially for users in emerging markets. My mission is to turn complex blockchain functionality into smooth, reliable products anyone can use.

🌍 Let’s Collaborate

If you’re building something on-chain and need a developer who understands multi-chain architecture, UI/UX, smart contract flows, and crypto-native user behavior, I’m open to collaboration or contributions.
