Senior🎓
Top SchoolAlex Mcgonagle is a Fullstack Web3 software engineering consultant with 11 years of experience and 8+ years focused on building scalable Web2 and Web3 systems using TypeScript, React, Next.js, Node.js and EVM toolkits like Viem and Ethers. He has delivered production-grade infrastructure across multiple chains (Ethereum, Base, BSC, Ronin, Berachain, Arbitrum, Polygon) and architected high-throughput systems such as a transaction queue processing 9M+ on-chain transactions and real-time SSE notification streams. As a senior engineer and former co-founder, Alex blends pragmatic, maintainable engineering with strong client relationships and a bias for shipping—reducing Next.js build times by 50% and automating recruiting workflows to save 30 hours/month. He contributes front-end improvements to notable open tools like revoke.cash, improving wallet connectivity and multi-chain RPC support, and often replaces inefficient RPC patterns with indexed solutions. Based in Lisbon, he combines product-minded consulting with hands-on implementation across frontend, backend, and blockchain integration.
