Mario Kenda is a software developer with over 10 years of experience, including 4 years in Web3. He led the frontend development of RabbitX Perps DEX from the ground up—helping the platform reach $1 billion in daily trading volume—and contributed to Morpho Labs’ dApp v2 (opens in a new tab), a non-custodial lending and borrowing protocol with over $5 billion in total deposits.
Mario specializes in frontend Web3 development using Next.js, ReactJS, and TypeScript. He also has hands-on experience with backend technologies (Node.js) and lighter smart contract development. Prior to his work at Morpho and RabbitX, he built a dApp for Strips Finance, enabling interest-rate derivatives trading on Arbitrum. His career spans InsureTech and DeFi, reflecting a deep passion for blockchain innovation.
After his tenure at Morpho, Mario shifted his focus to delivering comprehensive Web3 solutions. Collaborating with a freelance designer and a team of developers, he covers every stage of a project—from product design to frontend, backend, and essential smart contract integrations. He takes on select collaborations, oversees entire project development and continually explores emerging tools to deliver cutting-edge solutions in the Web3 ecosystem.
In parallel, Mario runs AdriaMed (opens in a new tab), his own healthcare development lab that remains a side venture alongside his primary Web3 work. It builds on his earlier path — upgrading the Think!EHR health platform at Inova and digitizing insurance claims at Paysure — so his fluency in healthcare systems is earned rather than incidental. For medical practices and diagnostic centers he builds guided online booking and bilingual solutions with EU-based processing, AES-256 encryption and GDPR compliance, storing no patient data.

Mario and his team build any kind of app for Web3 companies, covering every stage of a project — from product design to delivery.
Product thinking before pixels: flows, interfaces and a design system shaped together with a dedicated designer — so the build starts on solid ground.
Fast, responsive interfaces in Next.js, React and TypeScript — the same stack behind exchanges that have cleared a billion dollars in a day.
Node.js services and APIs that keep the app talking to the chain, indexers and third-party systems — reliably, at all hours.
Wallet connections and smart-contract integrations, handled with care — the part of a dApp where mistakes cost real money.
