PROJECTS

Interverse

Interverse is a platform that auto-generates an embedded MPC wallet through Google login and seamlessly connects to external wallets. This establishes a bridge between the embedded wallet, which handles essential NFT signatures for external wallets, and the external ones. I was instrumental in developing a Relayer server, streamlining communication between the embedded wallet, relayer server, and smart contracts. This setup allowed transactions to be logged into smart contracts using Google login credentials and digital signatures.

Fortress Arena Marketplace

Fortress Arena is a web3 game that utilizes in-game tokens and Lucky Ball. Currently launched in the Philippines, it's a PvP game where tanks battle against each other. I participated in the development of the marketplace made with Svelte and Seaport, supporting the trading and staking system for the NFTs used in the Fortress Arena game.

P2E Hunt

In my P2E Hunt project, I collated data from various Play-to-Earn (P2E) games, delivering key insights such as player counts and earnings per hour or day using the Alchemy API and Node.js. I was responsible for computing, storing, and presenting both real-time and historical P2E rankings via an in-house Node.js and MongoDB API. This data was showcased on a user-centric frontend developed with Next.js, elevating the experience for P2E game enthusiasts.

Red Conveyor

Red Conveyor is a conveyor manufacturing company based in South Korea. Leveraging Next.js' new feature, App Router, and employing Responsive views with TailwindCSS, I created an interface through which customers can send emails using an internal API. While other conveyor company websites often use outdated HTML, Red Conveyor takes a different approach by using Next.js to focus on SEO and maximize the effectiveness of a conveyor manufacturing company's homepage by optimizing the funnel for potential clients.

Radar Relay

Radar Relay is a decentralized exchange built using the 0x Protocol, established in 2017. The exchange stores its order book off-chain and assists in broadcasting signed order books to the blockchain when executing transactions. I contributed by simplifying the complex original version and introducing dydx's lending and borrowing system to the DEX. This allowed users to trade tokens and manage their basic portfolios effectively.
