I’m Elmar Kenigs, a lead full stack software engineer focused on decentralized web applications (dApps) and scaling production-grade Node.js/TypeScript systems. Over the past 10+ years, I’ve led end-to-end engineering efforts across frontend, backend, and cloud infrastructure—especially in the Web3 space—while partnering closely with teams to ship reliable mainnet-ready products. Most recently, I led a team of engineers through the launch and delivery of multiple dApps, owning technical architecture and hands-on implementation from user interfaces down to integrations with blockchain and storage providers. I enjoy turning complex cross-chain and wallet interactions into maintainable software, and I’m passionate about building strong testing and delivery practices so teams can move fast without sacrificing quality.…I’m Elmar Kenigs, a lead full stack software engineer focused on decentralized web applications (dApps) and scaling production-grade Node.js/TypeScript systems.
