One of our successful collaborations is with Blocklogica agency, based in Italy. Our mission was designing and developing a landing page with the latest trends in the blockchain industry. In this project I led the frontend development. In the development process, our main focus was on creating creative animations, such as scrolling pagination. A significant challenge arose as the client required frequent data updates on the site. To address this, we used TinaCMS, a git-based static CMS. This choice not only facilitated seamless content management but also made data accessible directly from GitHub, ensuring efficient and dynamic updates to meet the client's evolving needs.

In this project, I had the opportunity to contribute to a blockchain economic interface featuring a Mint NFT section and a daily lottery feature. These components presented intriguing challenges that required innovative solutions. While currently unavailable in the production environment, you can explore them within the development branch of this Next.js application, which offers a decentralized economic solution built on the Ethereum platform. Users can mint NFTs, participate in lottery games, and more. It's worth noting that I served as the sole frontend developer on DedogmaDAO's dedicated technical team. the auction part doesnt work currectly right now as the rpc server is down but you can explore them here: https://demmortaltreasure.vercel.app/gameboard https://demmortaltreasure.vercel.app/auction Technologies: React Next.js WAGMI Ethers.js Tailwind CSS Framer Motion PostCSS JavaScript typescript CSS HTML

In this project, I led a frontend team of four developers in creating a financial interoperability layer that links the entire web3 ecosystem, facilitating effortless value creation through crowdlending. Our dashboard streamlines the process of opening positions in various services, such as Aave, GMX, call options, fixed yield, and more, all within a unified platform. Furthermore, I also took the initiative to deploy contracts on a fork of Arbitrum as a testnet. This strategic decision allowed us to maintain full control over the testing environment, granting us the freedom to conduct extensive testing without the constraints of test tokens and other limitations. This hands-on approach to testing further enhanced the reliability and robustness of our blockchain solutions, ensuring they met the highest standards of quality and performance. link to the platform: https://app.ithil.fi link to website: https://ithil.fi

In this project I contributed to building a cross-chain DeFi lending protocol on Polkadot. I developed both the marketing landing page and the core platform application within a Turborepo monorepo architecture, leveraging Next.js 15, React 19, and TypeScript. On the technical side, I built a comprehensive package architecture including the @repo/onchain package with full Polkadot.js SDK integration featuring custom type-safe RPC calls for lending operations (asset prices, user LTV calculations, pool data, liquidation markets). I implemented transaction hooks for core DeFi operations including supply, borrow, repay, withdraw, and collateral management, alongside liquidation marketplace bidding functionality. The platform features data-rich interfaces built with TanStack React Table and Recharts for portfolio tracking, market analytics, and liquidation monitoring, all optimized through TanStack React Query for efficient caching and state management. Additionally, I created the landing page featuring a 3D kylix (goblet) with impressive animations using React Three Fiber, enhancing the visual identity and user engagement. In my advisory capacity, I provided strategic guidance on Substrate chain integration patterns, custom RPC architecture design, and wallet connectivity solutions using Polkadot extension standards. I helped establish a scalable monorepo structure with shared packages for onchain utilities, UI components, hooks, and type definitions, ensuring code reusability and maintainability across the platform.
