Blockchain & smart contract engineer with 3+ years of Web3 development experience and backend engineering. Graduate of Web3Bridge and Semicolon Africa. I build cross-chain protocols, DeFi primitives, and full-stack dApps — competing and shipping across EVM, Arbitrum, Polkadot, Solana, Base, Flow, Stacks, and more.

Core Competencies:

• ⛓️ Smart Contract Development (Solidity, Rust/ink!, Cairo)
• 🌉 Cross-Chain Protocol Design & Bridge Architecture
• 🏗️ Full-Stack Engineering (Node.js, Java/Spring Boot, Next.js)
• 💰 DeFi Protocol Development (Lending, AMMs, Yield)
• 🏆 Multi-ecosystem Hackathon Builder
• 🔐 On-chain Security & Access Control Patterns

Arbitrum Open House NYC Buildathon | Rust (Stylus) • Solidity • TypeScript

Cross-chain messaging protocol built with Arbitrum Stylus, leveraging Rust-native smart contracts on the AVM for performance-critical bridge operations.

Highlights:

• ✅ Rust smart contracts compiled to Stylus (WASM → AVM)
• ✅ Cross-chain message verification and relay layer
• ✅ Gas-optimized vs. pure Solidity equivalent

Mantle L2 → Flow EVM (Flow GrantDAO) | Solidity • TypeScript • AI

DeFi protocol enabling businesses to unlock liquidity from unpaid invoices via on-chain factoring. Originally deployed on Mantle L2, ported to Flow EVM for the Flow GrantDAO program.

Highlights:

• ✅ Invoice tokenization as on-chain assets
• ✅ AI-assisted risk scoring for factoring rates
• ✅ Liquidity pools with yield for capital providers
• ✅ Multi-chain deployment (Mantle + Flow EVM)

Open Source | React Native • Flutter • TypeScript

Open-source mobile SDK for seamless wallet connections in mobile dApps via deep linking. Monorepo architecture targeting both React Native and Flutter ecosystems.

Highlights:

• ✅ Deep link wallet integration (MetaMask, Rainbow, Coinbase Wallet)
• ✅ Unified API across React Native and Flutter
• ✅ Monorepo architecture for cross-platform consistency
• ✅ Phased rollout starting with existing wallet deep link schemes

Solana Ecosystem | Rust • TypeScript • MCP Protocol • x402

AI-native payment orchestration layer on Solana leveraging the MCP (Model Context Protocol) and x402 payment protocol for autonomous agent-to-agent payments.

Highlights:

• ✅ Agent payment rails on Solana
• ✅ MCP server integration for AI agent contexts
• ✅ x402 protocol for HTTP-native micropayments
• ✅ Composable payment primitives for AI workflows

Full-Stack | Next.js 14 • TypeScript • Prisma • PostgreSQL • tRPC • NextAuth

Production-grade employee management system built with the modern full-stack TypeScript ecosystem.

Highlights:

• ✅ End-to-end type safety with tRPC + Prisma
• ✅ NextAuth authentication with role-based access
• ✅ PostgreSQL with full schema migrations
• ✅ Responsive UI with Next.js 14 App Router

Full-Stack | Node.js • TypeScript • MongoDB • WebSocket

Comprehensive educational platform featuring real-time collaboration, course management, and student engagement tools. Built during Semicolon Africa training.

Highlights:

• ✅ Real-time features via WebSocket
• ✅ RESTful APIs with comprehensive documentation
• ✅ Authentication, authorization & role management
• ✅ Concurrent user support at scale

I'm actively seeking opportunities to collaborate on:
